Fix the Windows XP NVIDIA nv4_disp problem

Monday, January 23rd, 2006 by Chris Jason

Here’s an annoyance that found me today—the sinister “nv4_disp” problem. Hopefully my fix will allow other people to bypass any aggravation, unnecessary purchases, technician costs, or therapy.

The nv4_disp problem

I’ve had my Dell Dimension 8300 for about 18 months. It runs smooth as gravy. I haven’t installed any software in several weeks. I run virus checks and spyware removals regularly.

So wasn’t it great when my computer greeted me with the Blue Screen of Death (BSOD) this morning? For those of you unfamiliar with BSOD, it’s the screen you get when your computer is really screwed. Anyhow, my computer would boot up, show the Dell Bios screen, and then hit the BSOD. Every time I rebooted, same problem.

After booting into Safe Mode first and then rebooting the computer, I was able to get an error on boot that gave me some idea of the problem. The error message said that the “nv4_disp” driver was apparently caught in an infinite loop. My nerdiness came in handy as I figured “nv4_disp” reads a lot like “NVIDIA display,” my video card. Specifically, my NVIDIA Geforce FX 5200 video card. Perhaps I had found the culprit.

The nv4_disp fix

I was able to successfully restore my computer to tip-top shape in 5 easy steps. Here’s my 10 minute solution.

  1. Boot your computer into Safe Mode w/ Networking. For Windows XP users, this is accomplished by pressing F8 repeatedly when your computer is booting up. You will be presented with several options. Choose “Safe Mode w/ Networking.” This will boot Windows XP into Safe Mode, but you will be able to browse the Web.
  2. Go to NVIDIA’s Web site and download the latest display drivers for Windows XP. I saved the 20MB file to my desktop for easy locating later on.
  3. Remove the NVIDIA display drivers currently installed on your machine. To do this, right click on “My Computer,” then select Properties. Click the “Hardware” tab, then click “Device Manager.” You now see a list of hardware devices installed on your computer. Double click “Display Adapters.” You should now see your NVIDIA card listed. Click it once to highlight it, then click the “Uninstall” icon in the upper right of Device Manager menu. Say “peace!” as the NVIDIA drivers are removed from your machine.
  4. Install the updated NVIDIA display drivers. Double-click the NVIDIA setup file you saved to the desktop earlier. The installation will run its course.
  5. Reboot your computer.

After following these steps, Windows XP should start up as usual (prior to our little nv4_disp bug). Your “nv4_disp” problem is officially solved.

What caused the nv4_disp problem?

In short, I have no idea. I’m actually still trying to figure this out, so I welcome any comments about what could have been the cause. In doing some quick searches across the Web, however, I see that this is actually a common problem.

    WOW~ I have a mirror image problem (at almost exactly 18 months like you…make you wonder?) I am droppiing down the new driver after a 3.5 hour conversation with a few Dell Techs and I am very hopefull your tip helps, because thier ulitmate solution is to overwrite the operating system and that means me backing up all of my files first…..what a drag!

    I’ll let you know if it works for me too…..


  • Posted by: WALT | January 29th, 2006

    No such luck for me……still going amber and locking up when windows attempts to start…. ;O(

    Any other suggestions?


  • Posted by: Christopher Jason | January 30th, 2006


    Take a look at the Further Reading link I added today. Seems like there’s a ton of people having this problem, and just as many suggestions for fixing it.

    I too experienced exactly what you described. I followed your solution, and it worked for me so far. Thank you so very much.

    Mcafee anti virus got me the NV_4 Disp screen of death..while it was trying to update..right when I clicked update is when I started having the problems…computer ran fine till that moment..

  • Posted by: Brenda | March 18th, 2006

    My problem is with the GE Force FX 5200 too. I had the same problem…Blue Screen Of Death! UGH! I believe my BSOD was caused by a power outage. Contacted Dell – had no luck – just a lengthy phone call…did what you suggested and SO FAR SO GOOD! Thank you so very much! You saved me at least some aggravation, wish I would have found this sooner! Thx – Brenda

  • Posted by: Stevi | March 19th, 2006

    Having the exact same problems as everyone else. just about to call Dell, but I will try what you have suggested here. System: Dell dimension 8300, GE Force FX 5200. It was worked perfectly for just over two years, until this BSOD issue — have not installed anything new for a few months. From other messages boards, it seems like this issue has increased in popularity over the last few months (a signficant # of posts are from Jan 2006 on — very interesting)

    Thank you soooooooooooooooooooo very much. I tried this and it worked. Thank you for taking the time to share this with everyone. I REALLY appreciate it.

  • Posted by: jvick | June 7th, 2006

    exact same problem, even to the 18 month part.

    the fix you listed worked perfect!

    thanks a bunch!

    praise the Lord!

    Worked perfectly…Thanks o gracious Nerd.!

    It may be the driver, but double-ckeck your vedio card.
    There are some capacitors on your vedio card, make sure they all are good.

  • Posted by: bigG | June 20th, 2006

    tried this with my 6200, but did not solve the problem. The bsod constantly happens when I play certain videos through wmp. Im gonna RMA the card.

  • Posted by: james | June 22nd, 2006

    this has not worked for me either. i have a 6800xt gefore pci-e card. i have gone through one thinking it was the card. i rma’d it and got another back. same problems. i have reformatted the system twice now and tried various new drivers that have come out recently. nothing seems to work with it. i am switching to ATI seeing that this nv4_disp error is nvidia related. seeing many forums that people who switched to ati had solved their problems. see what happens…

  • Posted by: dave | June 25th, 2006

    Hey all, I have had a very similar problem. My screen would just freeze whenever I played games. I found out that my fan on my FX 5200 wasn’t spinning correctly. I added some oil, and so far so good, no more problems. I’m sure this isn’t the case for several, but I thought I would share.

  • Posted by: Kildian | June 26th, 2006

    hmm..i had this problem months ago and after it had been fixed, the problem came by again..
    do i just need to follow the steps again?

  • Posted by: Kildian | June 26th, 2006

    after doing these steps, the problem is still there =(

    no luck…

  • Posted by: Scott | June 28th, 2006

    the fix seems to have worked on my Dell 8300 with the geforce5200 card, but the only way i could make it work was not to delete the hardware. when i did, the nvidia install shut down because it said there was no compatible hardware .. anyway, thanks for putting me on the right track — i wish i could say it only took me 10 minutes, but the hour or so was time well spent.

  • Posted by: Michele | July 2nd, 2006

    Had a Dell Dim 8300 nearly two years working fine . . . but missing shodocvw.dll file is what began, which lead to nv4_disp, (for a while could manipulate the computer through Task Mgr to try to learn what happened), and now only the BSOD. I attempted your fix after finding, but seems too late. When booting in safe mode with networking, get only black screen with safe mode in each corner. What am I to do now? Buy a Mac? That is already on the agenda!!! But I want this expensive Dell computer to run properly!!! Michele

  • Posted by: Trey_135 | July 5th, 2006

    great job man i wish there weere more people like you that just give it as it is. i had the same problem with my Dell 4500 this solution fixied it right away and i also do belive my mcafee had a hand in this i didnt see the BSOD till i put that on there just thought id spit that out

  • Posted by: naomi | July 9th, 2006

    My Dim8300 reacted exactly the same as Scott’s (comment #18), but rebooting and then upgrading the driver over the old version seems to have fixed the problem.

    thanks for the thread!!

  • Posted by: Scott | July 16th, 2006

    just had the problem again this a.m. while using google earth. machine froze, gave me the bad nv_4 message. i turned off the power, waited and rebooted. nothing. waited, tried again and up comes a screen inviting me to boot into safe mode or use last known safe configuration, which i chose. all’s normal so far.

  • Posted by: zojac | July 18th, 2006

    I have the same problem, but being a few months later, it looks like they’ve got a new release Release 90 6/23/06. Think I should try that or stick with release 80?

  • Posted by: zojac | July 19th, 2006

    As an adendum to my prior post. The card I have is almost 4 years old. Is that a problem?

  • Posted by: Rick | July 23rd, 2006

    Thanks alot! My son brought home his computer with the BSOD. Interestingly, also about 18 months old, a Dell Dimension 8300 with an NVidia GeForce FX 5200 graphics card. I followed your suggestions and we once again have a functioning computer and a happy college man.

  • Posted by: Anthony | July 31st, 2006

    hey there all
    yeah i ve got the same problem except mines a geforce mx 4000. I am trying your suggestions now so hopefully some luck.

  • Posted by: Kevin | August 2nd, 2006

    Thank you so much for the help!! I have a 3 year old GeForceFX 5200 card and your suggestion fixed the problem immediately.

    I’m glad I didn’t have to resort to plan B – which included a baseball bat

    My Dell 8300 series is like 3 years old and I got the BSOD yesterday. So far your easy to follow instructions have worked! Thanks

  • Posted by: Sis | September 1st, 2006

    I got a px6800 ultra and it dose like that only if i try to play a game…and then blue screen comes up with the nv4_disp error. Its like this: when i first boot the pc i can play for like 10 mins…the time being reduced each time the pc restarts due to the error… its like something warms and i cant play anymore…any suggestions? PLSSS

  • Posted by: Sis | September 1st, 2006

    Soz to bother again but i already have the new 40 mb driver pack from nvidia 91.31 whql….so what can it be?

  • Posted by: ThEvAnDaL | September 1st, 2006

    what he said might not be true…in fact its bullshit….my nv4_disp error was down to over heating…..maybe thats just my comp but investing in a fan sorted it for me….but driver error might be to blame….mt advice would be to look for specific driver for your card and not use the forceware all in 1 driver

  • Posted by: Steve Bennett | September 10th, 2006

    i have tried your solution to this nightmare of a problem and thanks to you, i can forget about that problem. once again thank you for your easy way to fix my pc

  • Posted by: KL | September 19th, 2006

    Thanks – I had this problem after installing a new GeForce 6600 – but it only happened when using an internet or file brower (IE, FireFox, Windows Explorer). I’ve just finished your trick (couldnt download file in safemode, but did it in normal startup and accessed in safemode), and it already seens to be doing a better job – will keep you updated. Thanks a lot :)

  • Posted by: KL | September 19th, 2006

    Oh, sorry to flood a bit here, but can someone from Nvidia please take note of this problem and put a fix out?? This is a mojor problem for at least 2 cards by the look of it, so please sort it. If anyone could forward this thread to anyone working in Nvidia it would be much appreciated by all Nvidia users. Thanks.

  • Posted by: KL | September 21st, 2006

    Ok, bad news, my computer seems to be doing the same thing again. I’m going to reinstall XP at the weekend (day after tomorrow) and see if that makes any difference.

  • Posted by: CJ | September 23rd, 2006

    I was optimistic when reading and trying out the possible solutions however it did not work in my case. These articles got me on the right track since I have GeForce FX 5200 card. I have updated with the latest nvidia drivers but when I try to play a DVD, to test if it resolved the issue, the system hangs and I have to reboot it. I guess I will have to experiment with other video cards.

  • Posted by: Colin B | October 9th, 2006

    Having tried Microsoft website and downloaded all their latest patches – didn’t help. Then Dell for another web suggestion – again no good. To Chris’ NVIDIA site for a 6 hour download that fell over half way thru even with an 8Mb Broadband connection. What’s a donwnload accelerator and how do you disable it? Trying again this time to Save rather than Run. I’ll check when I wake up in the morning.
    Thanks for getting me this far. More to come…

  • Posted by: Colin B | October 10th, 2006

    Timed out again. How come a 20Mb download takes 5 hours? Trying again in Normal mode. Otherwise will have to find out how to switch off/extend Broadband timeout. Also what driver does Safe Mode use? Surely it can be copied to the standard one’s place? I am able to see what I’m doing cos I put a copy of nv4_disp from another XP onto a memory stick and copied it to System32. More to come…

  • Posted by: Mutlu | October 13th, 2006


    I have Latitude C840 notebook with the same nv4_disp problem. I followed your steps but ran into problems when trying to uninstall the nvidia display driver under display adapters as I simply cannot see an adapter called nvidia. Instead, I have a driver called “C840″ which I removed and when I try to install the new driver I downloaded from nvidia, the installation dies with the following error “the install software cannot find associated hardware so it will quit” so I cannot install the new driver. Any help to get over this problem will be greatly appreciated…


  • Posted by: Claire | October 25th, 2006

    Yes this looks to have fixed the problem. I have a dell inspiron 8500 and it is just out of its 3 year warrenty.

    It was just great to fix DIY.

    I will say that we have just given the laptop and the desk top recently more memory. I think that we almost expect too much out of the machines and underestimate how quickly stuff moves on and how much rubbish gets into the machines even with good virus checkers and sometimes the only fix is more memory

  • Posted by: Claire | October 25th, 2006

    Please take my comment back it didn’t work.

    It wont recognise the drivers
    I have kids wanting to do their homework. It is the same message as Mutlu above.

  • Posted by: Jason Carver | November 20th, 2006

    In reguards to the video hanging on Windows XP, This only happens on the Geforce 6200 PCI Card, and anything 6200 or higher that is an AGP Card. This behavior does not appear however in PCI Cards. Its a buggy Bridge that they use in those cards. Eg PCIE to PCI Bridge and so forth.

    The only way to view videos again in this situation is to downgrade to the 84.21 drivers.

  • Posted by: Jason Carver | November 20th, 2006

    oops, I meant this issue doesnt happen in PCIE Cards! Im major tired!

  • Posted by: Buck | November 24th, 2006

    Didn’t work for me either. Downloaded the updated drivers for Nvidia 7400 (my Sony Vaio) but when I tried to install the new drivers I got a message that it couldn’t find find or recognize and conked out.

  • Posted by: JuanBuck | November 25th, 2006

    Followed your instructions and it seems to work!! I tried everything, this was the last chance before I tested Newton’s discovery from the 10th floor with my PC…. txs

  • Posted by: olivier | December 1st, 2006

    I’ve got two issues. Dell Dim 8300 is about 2 years old but the symptoms are less than 5 days old.

    1 – Video screen begins to freeze when my kid is playing Madden 07

    2 – nv4_disp error appears before XP finished booting.

    The problems are not consistent but appear at least once or twice per day.

    I’ve tried updated drivers from Dell’s website and from NVidia’s website. Symptoms still there.

    Since this problem is entirely new and there’s nothing new on the PC, one would have to think that it’s one of the following:

    1) Hardware failure
    2) Memory Failure
    3) A recent XP update (is this a possible cause?)

  • Posted by: Paul | December 14th, 2006

    Like a few others here, I have a Dell 8300 with an nVidia FX5200, nearly 3 years old. The monitor started flashing on and off and I got the blue screen with the nav4_disp/infinite loop error message. I went through the diagnostics with the Dell technician and we reinstalled the video card drivers. But that did not solve the problem. The problem was four burst capacitors on the video card. They had actually swelled up and exploded (literally) one by one with a loud pop over a period of several weeks, and leaked some kind of gunk. I had heard these noises from ‘somewhere’ inside the tower over a period of several weeks and assumed they were some kind of static discharge or whatever, and hoped whatever it was would ‘go away’ as the PC seemed to be running normally. But when the monitor problem occurred I found out what the noises had been! Dell phone support was very good indeed and they sent a replacement card within 24 hours which fixed the problem immediately.

    I guess the 8300 cooling system and the nVidia fx5200 card just don’t suit each other very well?

  • Posted by: Christopher Jason | December 14th, 2006

    Paul’s comment above is the perfect lead in to the follow up of my story.

    About 4 months after I applied my fix above (around May 2006), the problem started occurring again. My fix didn’t work this time, and since nothing changed on my PC I was immediately thinking hardware problem.

    Opened the case, took out the card, and what do I find? A SIZZLING hot video card. Actually hot enough to burn a hand if I held onto it. This is consistent with capacitors burning out, and other people have reported this problem as well.

    So my fix above, at least in my experience, worked but only prolonged a bad video card from dying. I replaced the video card after I found that it was overheating (a nice way of saying 1 degree away from bursting into flames!) and my new card was an immediate improvement.

    For anyone who tried my fix but continues to have the same problem, I would open up the PC immediately after the problem occurs (turn it off first, of course) and check to see if the card is unusally hot. If it is, call Dell. Seems from Paul’s reponse that they will send a replacement. And based on the popularity of this page, it’s clearly a known issue. Wish I knew this in May, because I paid out of pocket for my replacement card.

  • Posted by: Paul | December 15th, 2006

    “Seems from Paul’s reponse that they will send a replacement.”

    I’m on a ‘Next-Day-On-Site’ maintenance agreement with Dell, which is why they replaced it immediately. The failed card is exchanged for a refurbished card – you don’t get a new one, unfortunately.

  • Posted by: greg | December 26th, 2006

    i have the dell 8300. the fix seemed to work. dell support tried to help but they said it could be a hardware problem. they tried their own update on their site and failed. i ordered a new video card. i came across this sie and the fix worded with his recomened driver. i canceled the order and saved money

    Has anyone had the nv4_disp infinite loop problem with a Gateway? Symptoms described in previous posts sound similar to mine. Also, right before the computer crashes a yellow grid pattern about 1″ x 1″ appears under the cursor.

    He tenido el mismo problema de pantalla azul debido al controlador nv4_disp.dll en mi AMD64 con un GeForce 5200 de 128MB y luego de mucho renegar pude solucionarlo con la sugerencia encontrada en este link:


    [i]Right click-mouse over My Computer
    Device Manager(button)
    Click [+] next to System devices
    right-mouse on CPU to AGP Controller (or whatever your controller is called)
    Update Driver(button)

    Select Install from a list or specific location (Advanced)
    Select Don’t search. I will choose the driver to install.
    Select PCI standard PCI-to-PCI bridge



  • Posted by: Scott | January 8th, 2007

    The nv4_disp problem on my Gateway has been resolved (see Post #53, 12/27/06). The fan on the video card died – once the card overheated it stopped functioning properly and caused the infinite loop problem. $75 for a new card. All is well now.

  • Posted by: Frits | January 10th, 2007

    I have a Dell Dimension 4600, had exactly the same problem.

    I followed your advice with succes. Thanks a great lot!

    Actually, the Nvidia drivers are now installed automacically after download, so it’s even easier than described above.

  • Posted by: Ronny | January 12th, 2007

    Thank you soo much. It worked. I also had a message “there was no compatible hardware”. but it was intstalled the first time. Thanks

  • Posted by: Luke | January 18th, 2007

    Another method to try before replacing a card (But by the looks of it, its a hardware problem…) Is to start up in wateva mode you can which allows u to get internet access. Follow a similar procedure as first outlined, go to hardware manager and select your graphics adapter, and hit delete, confirm it and ensure it has been removed.


    Option 1 (For people with onboard graphics)
    After switching off the pc and restarting it with the monitor in the on board graphics boot up in wat eva mode will work (once again with internet access) and this time download drivers for a completely seperate card EG a ATI 9900 or something and install them.
    (This will then overwrite all NVIDIA .DLL files with ATI ones ensureing none are left over. restart your pc again and then once booted install the NVIDA 7 series drivers (anything in the 77.7 72.2 79.9 etc etc) these drivers use the least Direct X features and card features, and the Ge Force 5200 is a Direct X 7 Card only, it doesnt support the later features, the 6200 6600 and 6800 range from direct X 7 8 9 (in order as listed) once installed the drivers restart again this time with monitor in the G Card port. Hope fully this has resolved your problem.

    Option 2 (For Peopl WITHOUT On Board Grpahics)
    Follow the same as above but DO NOT RESTART and DO NOT swap monitor cable to anywhere.

    /* I Highly recommend checking your G Card for signs of over heating but if you either cant tell or jsut dont know if the G Card is over heating try this method */

    Note: You can go to Start > Run > “Type in” DXDIAG and go to the graphics car settings, reduce all hardware acceleration, restart your pc and then run the tests on the DXDIAG page, if you pass them try increasing your hardware acceleration gradually until either u hit full accelleratio nwith no problems or you hit a accelleration level that causes a problem.

    Thanks for reading hope ive helped if not contact me directly on


  • Posted by: Luke | January 18th, 2007

    /* Update /*
    Another simple thing to do is ensure your G Card is firmly in the AGP, PCI or PCI-E port inside your pc. Check this by opening your pc case and locating the Graphics Card, (Usually and long thing circuit board in a AGP (Brown) PCI (White) PCI-E (Small White) port. remove the card totally and then re insert it firmly until it is level in the port and no parts are protruding (Sticking out of) from the mother board.

    I got a Dimension 9150
    with a nvidia 7900gt/gto card in it i cant get rid of the BCOD (nv4_disp error) i have tried reinstalling grafic drivers like 30 times, updated my bios from dell and checked my hardware, but the problem is still there what a load of crap. Any ideas?

  • Posted by: brian | January 25th, 2007

    Have a Dimension 4600 with the 128 mb ddr NVidia Geforce FX 5200 card. Will be 3 years old in March and the nv4_disp infinite loop error was occuring on boot with a BSOD. Went to Nvidia site and downloaded their driver(93.71) but on install It said no compatible hardware. Tried Dell site and installed ok(A07) but it did not help the problem. Then downloaded the driver(81.98) from your link which was different from my first Nvidia download. It also gave a incompatible message, but I was able to install it after a reboot by specifying the file I wanted to use. After this file installed I was able to boot again. I am up and running and it appears ok.

    Dell Dimension 4550 with GeForce 4 MX 420 recently stopped booting into Windows XP Home SP2. BSoD

    Formatted HDD and installed Dell Reinstall CD SP1, then SP2 = No Problems

    Microsoft update: 3 mandatory updates – KB892130, KB898461 and Installer 3.1 = No Problems

    Back to Microsoft Update: 60 Critical Updates installed = Reboot = nv4_disp BSoD

    Found this page.

    Uninstalled Display Adapter in safe mode, but 93.71 Forceware would not find supportted hardware until I rebooted in Normal Mode.

    My Conclusion: One of the Windows Critical Updates causes the BSoD if the NVIDIA Drivers aren’t up-to-date.

  • Posted by: Bob | January 28th, 2007

    Dell Dimension 4550 with NVIDIA 64MB GeForce4 MX 420

    More Details:

    NVIDIA website provided ForceWare 93.71 which installed Driver dated 10/22/06 and my system works

    Dell website provides V42.38 A03 dated 5/6/2003 – which I decline

    Microsoft Update lists as a High Priority Update – NVIDIA GeForce4 MX 420 v52.16 dated 8/2/2004 – I also declined

    So, my conclusion, Microsoft Update is pushing out as a High Priority Update an old driver that breaks machines. In my case, Dell Dimension 4550 with NVIDIA 64MB GeForce4 MX 420

    Users that automatically download all High Priority updates offered by Microsoft Update (as they should) are having their systems trashed.

    Nice Work!

    Dell should have a link to this site. This problem seems to be more with an issue with Dells then the Nvidia Chipset Display Card itself.

    Just say NO to MS Updates concerning Nvidia products :>

    Especially Dell….

    Working my way through the same problem. Dimension 4600 with Nvidia FX 5200. Tried the driver update first, but after unsuccessful attempts with different versions I checked the hardware. Looks like two of the four large capacitors are blown. On hold waiting for Dell right now to see if they can send me a replacement.

  • Posted by: Nate | February 4th, 2007

    Update to my Dell experience: After talking to multiple tech support reps and getting nowhere, I finally asked for a supervisor. The regular reps would only give me a part number and transfer me to the spare parts department which is closed on a Sunday evening (of course). After I raised some hell, the supervisor agreed to send me a new (refurbished) FX 5200 after determining that there were not any other damaged parts on the motherboard. If you have to call Dell and you are outside of your warantee, call 800-385-3355 (expired warantee department) and ask for a supervisor. Tell him/her that you read about the known capacitor issues with this video card and see if that gets you a new one. Good luck.

    The issue is with the BIOS and RTC. It’s not a short term fix for software. There is a hack for the nv4.dll which address the issue by adding some lines to nv4.dll. Also upgrade you MOB BIOS

    nVidia by large have ignored the problem. By downloading the new drivers only gives you the same results as if you were to delete all drive and reinstall them one by one with the nVidia driver last. If that works, good your fixed (until microsoft release another $hit update)

    Oh did I forget to mention that :) It’s not nVidia causing the problem but you knowew that.

  • Posted by: Danny | February 8th, 2007

    Ive seem to have found an easy fix for this. Go to Nvidia’s website and download(or redownload) the latest driver. After you download, restart your computer. After that, find the folder that you dowloaded into (Win2KXP)and click on the folder (ex.93.71) and the contents will pop up. Search for file names that have nv4_ in their name. Move them to the desktop/delete (removing the files will not affect performance). Restart and try it out :)

    couldnt you just remove the device from the device manager and get a whole new video card? like if you were thinking of upgrading anyway. any problems with that?

  • Posted by: Ian Webster | February 10th, 2007

    I read through all the fixes and patches here after I started to suffer big time from the nv4-disp / infinite loop problem. Having installed all latest nvidia drivers and after several days of thumping things, I decided to check the hardware acceleration settings in the nvidia control panel.

    From the control panel homepage, go to 3D settings; Appearance; Manage 3D settings and then check Multiple Graphics Card Acceleration. Mine was set to ‘Multiple Display Performance Mode’. I changed this to ‘Single Display…’ and all my problems have gone away.

    I can only think that recent driver downloads have had this setting as default – I certainly didn’t change it!

    excellent advice. dimension 4600 with fx 5200 had the bsod caused by nv4_dsp, downloaded the 93.71 update, quick and easy fix

  • Posted by: Dr. Wormready | February 14th, 2007

    My fix was realatively easy. For $59 I bought another FX 5200 card and replaced the old one. True to this thread, two of the capacitors were blown. Since tech stores are trying to move the old video card our of their stores, go buy a solution for a small price.

    Dell Dimension 4600
    NVIDIA GeForce4 MX 440 with AGP8X (Dell)
    Problem identified by message online as faulty display driver
    In addition to many of the problems described previously I find my keyboard frozen sometimes which generally returns to normal in a day or two.
    My problem is that Uninstallation of original driver in safe mode just does not work, whatever I try, even though it is seemingly successful and after what appears to be successful installation of the 81.98 driver that I want after the seemingly successful uninstallation I find that if I check the computer system details the original driver provided by Dell is still there with its date of installation.
    Would reinstallation of my Windows XP Home SP2 remove this original driver for good so that the 81.98 driver can replace it?
    By the way I have tried unsuccessfully to remove this original driver in safe mode by going to Device Manager and trying both Uninstall as well as Update to NVIDIA 81.98. It seems to get uninstalled successfully but after what appears to be successful installation of the 81.98 driver it just reappears after the rebooting.
    Please help.

    read through your threads since i was in the same predicament except that my system wont give me anything in my monitor even after reinstalling old and new versions of the driver in safe mode or VGA mode. got a nvidia 6600 on a non-branded system. no capacitors blown and the fan is working perfectly fine. changed some device settings for the card to go PCI-to-PCI bridge but still wont work. any suggestions?

  • Posted by: RobM | February 24th, 2007

    On Dell Dimension 8300, tried removing and reinstalling drivers for several hours; at one time or another got: BSOD with nv_dsp4; couldn’t change out of 640×480; 10280×1024 out of range; screen flickers on and off, mostly off. Windows Update history did not show any recent driver changes.

    Replaced fx5200 card with geforce6200 and everything is fine.

    One further test I could have done was switch from analog to dvi signal, to test the other output channel of the fx5200 card; but not going to do that now.

  • Posted by: Al S | March 4th, 2007

    I had the same problem, same computer. I tried the driver install and that didn’t work. I physically removed the graphics adapter and noticed 2 capacitors next to the heatsync have raised tops and are leaking fluid. Time to repair the adapter or replace it. The Dell repair tech that was sent to this owners house had no idea and was going to reinstall the OS.

  • Posted by: Jude | March 5th, 2007

    I have a Dell 8300 with NVidia FX 5200 graphics card and had the exact same problem ( PLUS an extra little quirk where I was unable to boot up into Safe Mode because I kept getting a Keyboard error which would not allow me to use either mouse or keyboard to log into Windows).

    Here is what I did to correct it:

    1. Restarted computer and pressed F12 to get into my BIOS where I changed the Boot Sequence to boot from the CD-ROM first, then Hard Drive. Put in my Dell boot CD for re-installing drivers and utilities.

    2. Re-started my computer and pressed F8 to get a menu where I chose Safe Mode. This was a slow process so far, so be patient and wait for it to get into windows under Safe Mode. Screen may stay dark with only four corners saying Safe Mode for a while, but don’t panic, it will continue to load on its own.

    3. Log into Windows with username and password.

    4. Click start, then settings, thensystem, to get a tabbed window. Click on Hardware tab. Find Display, and click it to get your video card (NVidia FX 5200 in my case) and double click the video card name.

    5. Click the button that says update Drivers. When offered the choice to do so automatically, or to choose from a list of available and compatible drivers, choose the second one where you manually choose the drivers yourself from a list.

    6. The window that opens next will list all the compatible drivers. In my case, I had two to choose from: The first one was called simply NVidia FX 5200 and the second one was NVidia FX 5200 (Microsoft Corporation). I chose the second one with (Microsoft Corporation) after its name, clicked Install, and voila!

    7. Next box says you must restart computer, so do so.

    There should be no more black screen and nv4_disp BSOD error.

    This seemed the simplest and least invasive change to try before doing anything more drastice. If you do this and it still doesn’t work, you can always reverse it the same way you just updated.

    This solved my problem and I hope it solves yours. If you do not have a similar configuration as mine, just try downloading the very newest drivers as suggested in this main post.

    (Note: I did not open my PC case and check the actual ideo card because I couldn’t figure out how to open the case. So I guess my card was all ok.)

    Best of luck.

    My card, just purchased, is the XFX version of the FX7600GT AGP8X in a P4 Intel board, with XP Professional SP2 and all O/S fixes. Latest board BIOS.
    Getting BSoD on startup or after several hours of gentle use, indicating NV4_DISP.DLL infinate loop.
    The drivers shipped with the card are installed.
    Can anyone tell me the version of the latest drivers, as there is some disparity between Nvidia and XFX and do XFX modify the Nvidia drivers before shipping?
    Finally who is responsible for fixing this problem, XFX, Nvidia, Microsoft, me?

    i had a BSOD recently with the error NV4_DISP.DLL drivers. i’ve tried all possible solutions and even went through reinstalling my operating system (windows XP) and still i had the same problem. replacing my video card resolved the problem.

  • Posted by: Phatty | March 14th, 2007

    I had the problem, utilized the information on your site and everything works. I thank everyone very much. Mine was not a hardware problem, only software.

    Also, the following “Driver Installation Tips” located on NVIDIA’s website helped me. Uninstalling the GeForce from my Device Manager was only part of the solution. Un-installing the NVIDA drivers from my Control Panel, in addition to uninstalling from the Device Manager, seemed to do the trick. See the tips, taken from NVIDA’s website below:

    Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel. Browse to the Start Menu > Windows Control Panel > Add/Remove Programs and search for “NVIDIA Windows Display Drivers” or “NVIDIA Display Drivers” and select remove.

    “Download Accelerator” utilities should be disabled when downloading any drivers.

    Do not run virus protection software in the background while installing the drivers. This prevents the driver from configuring itself properly.

    Thanks for your help. You might want to post this:

    I got the dang “nv4_disp infinite loop” error. I have a Dell Dimension 4600 with an NVIDIA GE Force FX 5200 graphics card. I read all of the posts that I could and did the following:

    1) I booted into safe mode without networking (f8), and logged on as administrator.

    2) I tested the RAM on my machine using Prime95 (for 5 hours).

    3) I removed the Nvidia drivers by entering the control panel > add/remove programs menu (and rebooted).

    4) I cleaned all vestige of the NVIDIA programs and drivers with Driver Cleaner Pro. I used six different drivers (one at a time, rebooting and removing as above) available on the NVIDIA and Dell sites.

    5) I removed and replaced (re-set) the video card.

    None of the above helped.

    I finally replaced my video card – and it works fine now! (I got a Radeon Diamond Stealth 9250 AGP-type card with 128 MB memory.)

    Good luck to you.

    The only time I got the dreaded nv4_disp.dll problem, was when I first installed my bfg gs7800oc.

    Basically the problem was my psu, it just wasn’t up to the task. New 550watt psu, and all is well.

    However a friend of mine is getting this problem, can’t remember what gfx card he’s using, but its definitely and nVidia, hopefully this will work for him.

  • Posted by: LJ | April 5th, 2007

    Please listen to the follow up from the guy who originally posted this thread!

    Your Video Card is most likely bad, and deinstalling and reinstalling drivers will only prolong your anguish!

    If you aren’t comfortable doing it, have someone else remove the card and check the bigger capacitors on it. I just replaced a friends because out of the blue her computer started getting the BSOD. She is not computer savvy, so I knew that she had not put anything new on the system, or changed configurations. I tried reinstalling the drivers just in case, but when that didn’t work I immediately checked the card and 3 of the capacitors looked blown to me, with gunk coming out. I replaced with a Matrox card I had, and she is back in business.

  • Posted by: Chris | April 12th, 2007

    I had a Dell 8300 with the GeForce 5200 card, with a DVI output. After three years of great service my screen started to flash after I booted this past week. After calling Dell and believing that I have a virus I decided to follow their request and reinstall XP.

    This was going fine till I installed the video card drivers, the same flashing started and I could only boot in safe mode.

    After 2 more hours of chatting with tech support I found this website and looked at the video card.

    Sure enough the two capacitors next to the heatsync had burst (with a raised top and yellow crusty crud on top of each of them).

    I ordered a new video card from Dell but the cheapest one they had came out to be $100 with tax and shipping.

    I guess it’s better than a new computer, but if I only checked the card before I reinstalled Windows (it would have been a much easier fix)

    Let me know if you have any questions,

  • Posted by: cpg | April 17th, 2007

    strangely, I was curious to what nv4_disp.sys was about. Now I know it’s an Nvidia thing. What I was looking for was the .pdb or the Symbol file for this module. It appears that there isn’t any. First of all some of the Kernels SSDT is hooked by this module. Being a Kernel/Rootkit developer I was interested in looking in further. For example:

    lkd> lm m nv*
    start end module name
    bf012000 bf463580 nv4_disp (deferred)
    f64ac000 f687b400 nv4_mini (deferred)

    It appears that Nvidia created it’s own System Dispatch table.

    Have the same BSOD problem with nv4_disp. Chat with Dell 4 days after the warranty expired. Dell Support sends me to the same NVidia Download and the driver did not fix the problem. Dell recommends replacing the card on a Dimension 4600. I removed the card and found 3 out of the 5 capacitors bulged out with chemical residue. Bad card. BAD BAD CARD.

    My computer will go BSoD (nv4 infinite loop) on either launching a game (LEGO Star Wars is one) or iTunes 7.

    The strange thing is, the computer is fine after it restarts – for as long as it’s switched on.. Games and iTunes load without problems.

    I’ve been through most solutions here including uninstalling and re-installing different NVIDIA drivers, adjusting hardware acceleration, disabling dual monitor display (I only have one) and checking the video card (a GEforce FX 5200) and RAM for damage/bad parts.

    I should also explain the computer is 2nd hand and maybe 4 years old. Bought from a friend, it worked fine when he had it. I formatted the HDD and installed XP (with SP2) with all my apps and drivers.

    So, just from scratch really this problem has been happening.

    Can the CMOS battery be the culprit? Or does anyone have a suggestion – something I might have missed?


  • Posted by: Franz | May 5th, 2007

    Heres a tip , i didnt have time to read every post, but when your getting the NV4_disp.DLL bsod, Unistall your Nvidia display driver, then reboot when asked to do so, when it loads up again ignore the windows driver installer. Instead, go to find, and search for nv4_disp Delete every entry you can find and i mean every single one. then empty your recycle bin, defrag. and restart when it comes back into windows install your desired Driver version, and you should be good to go. if it still continues to BSOD, check your memory using memtest 86, and prime your CPU to check for errors Both should be let to run for 10+ hours min. if both pass, consider the Powersupply’s rateings and and how much your computer draws total ( if you dont know search for extreme Power supply Calculator). i just struggled with this problem for about 3 days diagnoseing my computer as to why it was crashing durring gaming,

    ran prime. 12Hours
    ran Memtest. 12Hours
    Ran ATItool Scan. 6hours

    so then i installed a newer nvid drive right over top, still had the same Bsod

    so then i figured well it must be the PSU, because the CPU passed by it self, the Ram passed by it self, the Video card passed by it self,
    but when your playing games, your using them all at the same time. needless to say i was about 20 seconds away from buying a 1000W powersupply. then i figured out from doing my own research on the problem rather than complaining to someone else in a forum hopeing theyed for find the answer for me, that you need to manualy remove some files.

    if theres anyone out there that has a problem with nv4_disp error stuck in an infinite loop (bsod). i know how it feels.i have spent ages trying to track down the problem. alot of people said it is caused by the nvidia driver which is all wrong. i have done test after test and found compatability issues with spysweeper and nvidia drivers on a major scale. if you have spysweeper on your system then go into add/remove programs and remove it. then go into safe mode. when in safe mode go into regedit,{hot key local machine} go to current control set. look in all control set keys 3/4/5/6/7/8 for this system file SSKBFD.SYS which belongs to spysweeper and has to be removed. this is the problem that nvidia drivers get stuck in an infinite loop. or irq less or equal to errors. delete this key and any other keys that are from spysweeper. only do this if you know the registry. as removing a wrong key or keys could cause serious problems. dont forget the main key or sys.file to remove is SSKBFD OR SSKBFD.SYS. it has to be removed from the registry before you can delete it from the windows/system32. when your happy enough that spysweeper is fully removed from the registry, click start then click search. type in SSKBFD only. and click search wait till you see the file coming up and then delete it. restart your pc straight away . but you might notice a bsod as your shutting down but dont mind it. if this happens just manually power off the sys and you wont get that again. if your successfull that should be the end of your nvidia problem. this worked for me and i havint got the problem since. its 2 and a half weeks and everything is perfect. just tought id share this info with you cause it is a pain getting these bsod.

    if that doesnt work for you and if its a dell system. then try this… first download DRIVER CLEANER PRO. NOT drive cleaner pro. and install it. dont use it just yet. go into add/remove programs click remove nvidia drivers,and a small screen will come up, only place a check mark on (remove only the following) check mark nvidia display driver.remove it. when done go into safe mode when in there read the instructions in driver cleaner pro. to remove nvidia display driver, scroll down the list in driver cleaner pro for (NVIDIA) only NVIDIA and left click it. then on the right click start. a message will say are you sure you want to remove display driver files or something like that. click yes. when its done it will show you the deleted files. exit driver cleaner pro. if its a dell system you have. then when the above is done. click start then click search all files and folders, type in nv4 click search and it should still find nv4 disp.sys/32. and nv4 sys32 miniport. if you see these remove them. their from dell old display drivers which im sure are conflicting with the newer nvidia display drivers. driver cleaner pro does not notice these files so its best to search them. when removed start the pc up and install your new display driver. hope it works for you.

    nv4 disp error, a known issue with DELL computers and Nvidia cards. Nvidia and DELL both knew very well about this issue before the launch of the dimension 8300. This is a Marketing Tactic cover up used to exploit further money from unsuspecting customers.

  • Posted by: Shane | May 28th, 2007

    I got BSOD constantly no matter which driver I installed. I am using Geforce FX 5200. I uninstalled the graphics card drivers and have found my computer works fine without it. If you are not a gamer or do not need high end graphics, I suggest this. Nvidia have alot to answer for with the dismal quality of their cards to be honest. I was never a fan, but I cannot get any other graphics card (ati etc) to work in Dimension 8300. The truth is that both DELL and NVidia knew about these problems before even marketing these machines, this information was witheld from the public as money was given priority.

    Frankly, I think it has put me off both DELL and NVidia in the near and distant future! I would never dream of spending good cash on this rubbish ever again.

    I was struggling my computer for a week like an idiot, tried all drivers possible, but always got the nv4_disp BSOD. The only thing that worked was a very old Microsoft driver from 2001 who haven’t even let me run the media player.
    As an act of despair I removed the case of my computer and turned it on, looking at my card’s fan.
    I saw the fan was not turning, so i took the card to the nearest technician who replaced the fan (10$)
    and walla – my computer works again.

    Same problem with Geforce FX 5200 in dell. My advice before wasting alot of time with software, take the card out and look at the caps. I spent hours trying to get mine working and finally took the card out to replace it. Sure enough the two caps right next to the processor
    where blown.

    Dell Dimension 4600 had same problem. Used ‘The nv4_disp fix’ but driver would not load. Then realised that driver was for US only. Loaded international driver and rebooted, now everything works fine. Thanks.

    Thanks so very much. Went to use my Dell 8300 (3 years old) and was locked up. Power it down and that is when the problems started. Booted twice and got the same error (stuck in loop). Came up in safe mode fine. Lucky I have a laptop. Quick google search and found you site. Followed your directions and 20 Mins later back up and running. again Thanks really appreacite the help…

    none of the solutions seem to work for me i may have a slight diferent problem because instead of the blue screen of death i get a dark red screen and also when i reboot in safe mode my screen is completley screwed up and impossible to read which is y i have to use my parents laptop to even look at this site maybe its cause i have the nvidia 6800

  • Posted by: DigitalDemolition | June 18th, 2007

    the bsod and lockups are on account of the mhz frequency problem that incurred on thousands of peoples 6200 models,i got sick of trying to patch it as there is no software patch because its a hardware problem. i underclocked my card and it worked fine as if it hadnt taken any fps from when it came stock. f.e.a.r runs fix is found on google by typing nvidia 6200 loop fix, im digital demolitio,and one last note i even brought this up to nvidia that i had found a fix for there f-up and i got no reply, i wasnt even rude either. i just said i underclocked and they never replied. jerkoffs..

    Thank you so much for this WEB-site. It has helped me a lot. I also have a Dell 8300 – 2 years old. I tried to download the newest driver – that did not help, then I tried to take the videocard out (FX 5200) and put it in again – still same problem.
    In same operation I deleteed the driver, deleted all nv4_ – files from my hard disk, used the Reg Fix and DRIVER CLEANER PRO – install the new driver and yopti.. the display functioned again. I have used 10 houres to fix the problem but only with help from this Web site. Thank you to everyone.

  • Posted by: Mark W | June 27th, 2007

    Zenno thanks so much your posting on May 23 2007 for nv4_disp_fix
    I followed most of what you posted, but had to do it a little differently but it worked.
    I have a Dell 4600 with Nvidia FX 5200 with Windows XP Pro. One problem I kept having was the system would reboot then reinstall the adapter when I used the add/remove programs way of removing the nvida driver. I think I got around this with the following steps. Mostly the same steps as what Anne, France Says:
    June 19th, 2007 at 4:07 am

    1. Download new driver from NVIDA.
    (With Windows XP Pro download driver for XP not the 64 bit version, it would not install on my computer) (The driver I tried from Dell R75461.exe for the 4600 was old and did not work or fix my problem.)

    2. Download DRIVER CLEANER PRO and install. I may have also used Reg Fix.

    3. In safe mode then go to Control Panel (switch to classic view)/System/Hardware/Device Manager/ select the display adapter, double click, select Driver tab, select Uninstall the driver button.

    4. Run DRIVER CLEANER PRO only select only “NVIDIA” add to right pane then start/run. May have also ran Reg Fix here.

    5. Then delete old files from Dell: click start, click Search select C drive then search by typing “nv4” in search box. I deleted all the files windows would let me that had nv4 in the name.

    6. Then in Device Manger, right click on NVIDIA display adapter and select Uninstall.

    7. Run the new driver downloaded from NVIDA. Then reboot when it ask.

    I’m telling ya man underclocking is the only way, i even told nvidia that ,thats the only fix and they didnt even send me a positive feedback. i’m glad i helped anne france,at least some more people are fixing there fRIGGIN CARDS! :D

    Ok well I am having this problem with my nvidia 6600 on a Dell XPS 400. It has did it once while playing a game and at first i hadn’t a clue what happened. It did it again when bringing up mcafee secuity center followed by the BSOD which is when i realized something was really wrong. Upon getting that i booted up my machine and investigated as to what the nv4_disp was, walked away from the computer to get a drink and apparently when the screensaver came up, it had frozen and what not again. So i again booted up the machine so i could research it like im doing now and it will now immediatly have the color/screen distortion right at startup and after the window xp loading screen finishes, the screen goes black. I have tried to launch up in safe mode but after hitting F8 repeatadly the screen to select safe mode or whatever comes up but it is so distorted i cant read it to get out of safe mode or get to anything at all. Therfor i can’t get it online to download driver updates ect ect. I can’t get on my computer to uninstall it or do anything. I’m really quite clueless as to waht to do.

  • Posted by: Rob | July 8th, 2007

    Also oddly enough, i have had my card (which i bought with the computer) for only about 10 days over 18 months….

    I did what is in the post at “June 27th, 2007 at 3:23 pm”.
    First it didn’t work i was like OMG what to do now?:(
    Turned off the computer…
    But som1 said check the fan so i turned on and watched the fan. It’s worked correctly. Then i looked at the monitor and OMG!!! its good a working WTF??!?!

    So don’t just reboot after. Turn on and off.

  • Posted by: Haley Buxton | July 12th, 2007

    Dear Chris,

    I can not thank you enough. I was on the phone with a Dell Tech for 1.5 hours with no success. The final suggestion was that I reinstall Windows, which would have meant two weeks of agony to recreate my system. Your solution has worked so far, and I am keeping my fingers crossed. Dell had my reinstall a GeForce 5200 driver–apparently that is not the file needed to fix the problem.

  • Posted by: Penny | July 12th, 2007

    My 3 year old Dell Dimension 8300 & Nvidia FX 5200 also produced the nv4_disp error.

    Having spent several days installing different drivers and actively resisting Dell’s repeated recommendation to reinstall the operating system (XP Pro), I googled nv4_disp and found this article.

    I’m glad I refused the re-install option !

    When I dug in the heels, mentioned this article and insisted that the graphics card be thoroughly checked, Dell finally decided to send out an Engineer.

    He took one look at the card and said “a couple of capacitors are blown”.

    Ten minutes later a replacement (refurbished) card had been installed and I was up and running. Fortunately, being still within the 4yr warranty, there was no charge.

    Just one thing – recognising a damaged capacitor can be a bit tricky. In my case, the difference between good and bad was minute. Having read this article, I had examined them several times yet still failed to see the problem.

    The capacitors are cylindrical in shape and stand at right-angles to the board. On top of each cylinder there is a metal disc with an “X” engraved on it. The metal disc should be absolutely flat.

    In my case, two of the metal discs were very slightly dome-shaped and the now-stretched “X” threw a tiny shadow.

    I hope the above helps anyone else who may be trying to check for similar damage.

    Also, I’ld like to thank all the contributors … without this article I would now be tearing my hair out re-installing and re-registering all my software !

  • Posted by: David | July 21st, 2007

    Thank you. I had the same problem and these steps solved it for me. However, when I rebooted everything appeared too large on my screen. How do I shrink things down the way were before all this happened?

    I’ve got a custom built rig. I’ve tried drivers from latest ones to back drivers. Still doesn’t solve the problem.

I was able to start in safe mode and search the web and then I found your step by step solution. It worked and save me a lot of aggravation! Thank you so much!!! Well, this error is still out there – so keep it posted – it may continue to help others.

    Thanks for your time and efforts on distributing this type of information.

  • Posted by: IM | July 27th, 2007

    The nv4_disp problem found me last night. Thanks to Christopher’s instructions and Penny’s tips on recognising damaged capacitors (comment #141), I was able to fix the problem easily by replacing the blown card with a new one.


  • Posted by: Motorcity-Ken | August 2nd, 2007

    The nv4 blue screen surfaced a few days ago on my 37 month old Dimension 8300 with the 5200FX card. I updated the drivers and the BSOD at bootup time disappeared, but, I would still get a Microsoft detected serious error on my graphics driver at boot-up. I contacted Dell support and by reading this problem scenario, I believe I knew more than the Dell tech who wanted to reinstall XP. I convinced him to send me a new 5200 card out. Upon installation of new card, everything was fine again. Thanks, for this advice and knowledge.

    hello all.
    dell xps 600/ dxgo51/p4/3.8ghz/2000ram/dual geforce 7800gtx sli 256mb/650watt psu/raid 0… windows xp home. sp2.
    everyones talking about driver issues for their new cards but this problem is going on for as long as i can remember nv4_disp stuck in an infinite loop. nvidia have got to sort this out immediately if they don’t then i’ll never be buying their hardware again and the same is true for a hell of alot of people. i have had enough at trying to sort this issue out. example, last month i got this bsod nv4_disp error for no apparant reason. it just happened. then it started happening while playing games. so i tried to track down the problem for a day or two but could not find it.i uninstalled the driver and then used driver cleaner pro in safe mode to delete the nv4 dlls and mini files. and then restarted the sys. and installed the latest whql certified driver. but that did not fix the problem. so then i took out one graphics card and restarted the sys. then took out the other one and mixed them around still the same problem. so then i decided to do a complete clean format of the drive, and reinstalled xp. at this stage i never installed any programs or antivirus software because i wanted to make sure there was no incompatabilities with anything. the install went perfect and then i installed the nvidia whql driver for xp. to my astonisment after all this the problem was still there. so enough was enough and i rang dell xps technical support and they said to do what i already done factory install and the rest. so they sent out a technician with a new motherboard and two new geforce 7800gtx’s and installed the whole lot. and when he went i tried a game farcry and quake 4 they worked for a while and then believe it or not bsod nv4_disp stuck in an infinite loop error again. i could not believe it they just put in a new motherboard and two new graphics cards and the problem was still there. im lost at this stage. its the weirdest sys problem i ever came across. for gods sake NVIDIA will you at least try to find out the source of this problem it has been going on for years i have looked up lots of other sites and it goes back a long way..

    I have Dell dimension 8300 with Nvidia geforce FX 5200. I had pretty much exactly the same symptoms. Thanks to this I finally stopped going mad. Wasted days downloading and installing drivers. Opened the case and the video card had 4 blown 100uF 6.3V capacitors (Skywell SHT).

    Checked the badcaps web site and followed in part the tutorial on replacement of capacitors. 4 new capacitors @ 70c each (1000uF 16V) and system seems to be okay.

    I still sometimes get a power down/green light flashing on the e173fp display. Various reports on faulty transistors in monitor. Nearly opened up the video case but thought better of it. Tested the monitor on HP laptop and seems to be okay.

    Instead opened up the Dell computer again and had a good look. Found 1 leaking capacitor and possibly 2 bulging capacitors on motherboard near the power supply.

    All out of warranty of course. A client focussed company would consider a motherboard replacement policy. From the various forums out there including Dell’s it seems as though the company has known about the problem for quite some time.

    Thanks to this site I am much the wiser and will probably steer clear of Dell entirely.

    I need HELP!!If somebody can help me with this BSOD of Nv4_disp, that would be very helpful. I made a mistake by removing the previous NV4_disp from control panel, then download the new one into PC, but it appear that the new driver cannot find the compatible version from the previous driver. I wonder is it because I remove the previous driver or is it because I don’t know how to fix it. I kinda depressed here and need help from everyone of you. Please…..???

    I’ve had my custom built workstation for quite some time now (4 years at least); and I rarely turn it off. The other day my keyboard decided to not respons so I was force to restart. KB still wasn’t responding so I thought I was the kvm switch. Connected the kb directly to the workstation and got the 1st bsod. Didn’t pay attention as it all looked like a kb problem. Switched keyboards and got another bsod. This time I paid attention and saw the nv4_dsp msg. I googled, found your site, and fixed. I don’t use mcrappie, sorry mcafee, and I don’t own a dell. Must be a glitch in the nvidia matrix couple with a glitch and several other “matrixes”.

  • Posted by: The Computer Guy - Beloit WI | September 10th, 2007

    I don’t know if anyone mentioned it yet but the CAUSE of this issue is reeally quite simple. It is caused by the MSWindows Update for the NVIDIA video card. Don’t install the update and you don’t get the probem.

  • Posted by: Jed | September 12th, 2007

    Dell Dimension 4600, Nvidia GeForce FX5200 card, BSOD. Tried the fix. Didn’t work. Spent three hours online and on the phone with Dell tech support. Didn’t work. Installing a new video card to see if it solves the problem. Very frustrated.

  • Posted by: johnt | September 14th, 2007

    The BSOD can be due to Windows Update. For some reason best known to Micro$oft, they’ve made an update to Nvidia GEforce drivers a ‘critical’ one so it’ll get installed by automatic update. I was rebuilding XP Home on a Dell Dimension 4550 yesterday. After I’d run Windows Update, I got the BSOD with a mention of nv4_dsp. Booted up in safe mode, rolled back the display drivers & the problem went away. Installed the latest drivers from Nvidia, but Windows Update still wanted to install its version. I’ve now hidden that update to prevent it from having another attempt. HTH someone.

  • Posted by: Doug | September 15th, 2007

    I had same problem.
    But after I just rebooted my PC and it restarted normally (but with big font). Sudently it apeared on the bottom left a message saying: New hardware found. and it instaled for itself a new driver called FX5200 (Microsoft). Until now its working…(crossing fingers)

  • Posted by: Jack | September 25th, 2007

    I had the capacitors go kaput. I tried reinstalling the driver first and was able to boot to a Windows desktop, but the “your system has recovered from a serious error” dialog kept popping up. Tore it open and three of the capacitors were domed and had yellowish nastiness coming out of them.

    After replacing the card with another NVidia which runs off the same drivers, it took another driver uninstall/install cycle before the system became stable. I was tempted to throw in an ATI card instead but couldn’t easily find a cheapish AGP one locally.

    ive swopped my FX5500 with a FX5200 but does exactly yhe same thing. Isnt there a way to update the windows driver database without having to have the card plugged into the board? PLZ need help because its a bit of a risks nowadays running sp1 on the internet

    I’ve only just built a custom box about 3 months ago and all was running fine until I had a few high end games give me grief with the same error. I’m running an S-series board with AMD dual core 64-bit (but on 32-bit XP pro) along with a shiny new 512 MB G-Force 8500 GT. Needless to say, I have yet to find a game that would slow it down, not that I want to… but still, when I play games like Morrowind, Oblivion, Max Payne 2, Stubbs the Zombie and Tiger Woods PGA 2008 I end up crashing to the desktop, having the screen go black and being totally locked out, forcing me to cold boot or the dreaded ‘nv4_disp’ stop screen (usually happens 90% of the time if I leave the PC for a few seconds after the former problems, normally I lose patience and reset before I get the error). Now… I have reinstalled XP, tried to do what I read up earlier about not installing any other software in case of incompatibilities… same problem. Then I swapped graphics cards (same one, but new replacement), I still got the error only after about a week. I updated as far as the card could be done and ran these games with lesser quality settings to be sure… same problem, except I had Tiger Woods 2008 stop crashing, although I would then get weird polygon anomalies slowing the game right down shortly before getting the same blue screen again. I’m beginning to wonder if I should go back to my lesser yet more reliable 128 MB ATI Radeon Sapphire or perhaps cut my losses and buy a newer ATI. And I always thought that this new PC would be awsome with games… I’m so very sad.

  • Posted by: Shaque | September 30th, 2007

    Quick addition: I downloaded a beta “nv4_disp infinite loop problem” alleged fix… guess what? Same problem. I did a full uninstall of all NVidia drivers and the adapter, stopped Windows from detecting it and ran the newest forceware drivers available. Still the same problem. Only 20 minutes into a game and BSOD. I give up. Whoever wants to purchase this 2 month old 8500GT can have it for AU$100 (purchased for $232). I’m staying away from NVidia from now on. Seems this problem isn’t going to go away anytime soon.

    I bought a 7950 GT 3 weeks ago and started experienceing this POS problem too. I was told nVidia was THE company for kick A$$ cards.

    My issues happens only 50% of the time and it only seems to occur at the “select and account” screen in XP or shortly after you are loggin into your account.

    I have noticed that I was able to recover from the BSOD by moving the mouse when it was crashing. Maybe my issue is different then the others but I am still looking for a fix.

    Any help? Tried to call BFG and no one wants to answer the phone. I guess they know that I am trying to call.

    Shaque, I quote what you say on 3oth Sept. 2007,”I did a full uninstall of all NVidia drivers and the adapter, stopped Windows from detecting it and ran the newest forceware drivers available. Still the same problem. Only 20 minutes into a game and BSOD”. My good friend I came across the same problem befor as well and it is very simple to solve it.Heres my solutions:

    1. Just remove you NVIDIA Hardware and re-install it.
    2. If it still the same then throw it into you trash bin and get a new one from a vendor and install I believe it would work for you.

    Ive had my Nvidia 8500GT for a month now on a HP dc7600 (pentium D)
    2 weeks ago I changed to a Dell Optiplex 320 (Pentium D) and had problems ever since. Working on ArchiCAD 11 the 3d models disappear sometimes into a grey screen an shortly after the BSOD appears with the Nv4_disp message.
    Im guessing there must be drivers that Dell have pre-installed that are incompatible with my card. I’ll remove all display drivers and try the international version since Im on XP UK english

    Thanks. The infor here is quite helpful

    I let MS update do the nvidia update on a Dell Dimension 8200. On next boot – screen was black. Rebooted into safe mode – went to device mgr – did a driver rollback – rebooted. Fixed – reinstalled nvidia drivers from Dell – let MS update again – this time it worked for some reason.

I found many threads with the same problem since 2002 till this date even for latest 8600GT. Feeling bad that nvidia does not even want to recognize this(their site is silent on this). Hope I solve the problem, may be by that time I won’t even be able to recollect what solved the problem

    When I tired uninstalling the Nvidia driver, it told me it could not delete it because is was needed to boot up the computer…Has anyone else had this problem? What do I do now?

  • Posted by: Lynn | October 15th, 2007

    Thank you so very much! I too have a Dell Dim8300. I get very nervous when I try to fix things on my computer. But you made it so easy. AND it worked for me!

    I won’t guarantee it will be working tomorrow, but at least it is working now.

    Granted I did have to do some fine tuning afterwards, but it was all simple.

    Thank you so much for this fix!

    Thanks for the help. I’ll try it out. I had that problem so many times and even though I installed the most up to date version of my display driver, it still occurs and this only occurs when I play my game such as Medal of Honor Airborne and Company of heroes seris, but it’s annoy cos I got the latest drivers installed and why it keeps knocking on my door? Anyway, would great if anyone can suggest anything, thanks for the help anyway, I’ll try your method first.

    Inherited the Dell 8300 with the NV4 problem. I haven’t tried the new drivers yet but I noted that the video card in this 8300 is not labeled ‘NVIDIA’. Noted all the 6.3V 1000UP capacitors show signs of leakage. This might tie in with the 18 months, 2 years failure time mentiond in several posts. I will dig out some suitable caps and let you know the result.

  • Posted by: John Barrett | October 27th, 2007

    My son acquired a Dell 8300 recently, less hard-drive. Fitted 15G drive and loaded XP.
    Up came the nv4 problem. Having visited this site for help, I noted the frequency of the 18 month, 2 year time to fault. I removed the nVidia Model P162 card. Noted 4 1000uF 6.3V caps showing signs of leakage (tops bulging, dried deposit of leaked electrolyte) Replaced all 4 caps with new 1000uF 16V caps and problem fixed !!!! Total cost $2.80 ! If you are not a tech with experience in replacing components on multi layer PCBs, I recommend you find someone who is, to do this job for you.
    This problem seems to have been around for quite some time I can’t believe Dell and nVidia aren’t aware of the real problem.
    The caps on my PCB were marked Skywell SHT , I think a capital I was missing !!!

    This issue has been discussed all the way back to 2004, if you search forums on the net. Its just lately that there seems to be a flood of folks having this same bother.

    I have been experiencing this problem for some time. It seemed to become worse over a period of weeks until it got to the stage where it could barely stay running for a few minutes, then the moment I even opened IE it would hang. Oddly, the desktop would first stop responding and then if you clicked the mouse exactly 5 times, the mouse would stop responding too – then the crash and BSOD with the nv4_disp infinite loop error.

    I thought an ageing computer with corrupted files was the problem, so re-installed the entire system on new drives and got the latest drivers from nvidia for the card AND the latest drivers for my VIA chipset. Fine for about 3 weeks, and now suddenly I am back on the same path again. Random hangs – via 3D games, trying to run media player or when opening a graphically complex website. If I uninstall the nvidia drivers, no hangs. In safe mode, no hangs. I have tried the fix in this thread, it makes no difference.

    So my point is this: If it was a hardware issue, why would I get three weeks of problem free operation post-reinstall, then suddenly get these problems from nowhere? If it was a hardware related problem, such as weak CPU, AGP BIOS Settings, RX55 memory register etc etc etc, why would it work fine for three weeks and THEN have problems? Why would it work fine after a clean reinstall? The hangs now happen as soon as I access heavy graphics sites, a few moments after a cold boot – so it cant be overheating.

    It makes no sense and personally I am becoming very frustrated. I am thinking of buying a whole new system anyway – but given the amount of people having problems with nvidia cards here, the diversity of systems and processors that seem to be affected and the total lack of help coming out of nvidia, I have to say that my new setup will not be including an nvidia card.

    I just found out that nvidia’s latest geforce 6200 drivers mixed with that underclocking the core to 312mhz and memory to 370mhz, works! and they run way faster than 8x.xx or 9x.xx drivers

  • Posted by: Fred Flintstone | November 1st, 2007

    I also had this problem but unlike most of the other people here, I have an HP Pavilion 05 computer running Windows XP Home Edition (5.1 build 2600), 512 MB Ram and GeForce 4 MX 420.

    The problem I was having was that the screen would turn black and random times while I was doing random things running browsing the web, and even using notepad. Once the screen turned black, I couldn’t do anything although my computer was still running. The only thing that I could do was unplug and restart the computer.

    I tried the tips that were suggested on this webpage and I hope this will solve my problem as well. Thank you all for contributing your helpful tips!

    I have the Nvidia 6800 pro. I had the same problem. but no to the extent. It gradually starting getting worse. But only with one game. Dell Techs saids the game must be using part of the ram that none of the other games are using and it must me corrupted. I not a very computer literate person. I too am thinking about just having a pc built with another brand of video card. i have had too many problems with me dell pc. thanks for your info.

    Have this problem too, have spent DAYS updating drivers and trying all sorts of fixes – but just realized the fan on my Gforce has quit spinning… Guess I´ll go with the overheating hypothesis and be buying a new one…!

  • Posted by: Elaine | November 3rd, 2007

    Ok. Everything was going smoothly until the setup when it was about to install the updated NVIDIA display drivers a error message popped up and it said
    “The NVIDIA Setup program could not locate any drivers that are compatible with your current hardware. Setup will now exit.” It basically didn’t do anything but thanks for your help you gave me a glimpse of hope.

    At last a website that addresses my problem! I also have a dell dimension 8300 with graphics card geforce 5200, my screen was flashing and crashing for TWO MONTHS! tried everything from reinstalling video drivers, reinstalling WMP AND DIRECTX (as it seemed the problem was predominant during the run of these like bigG in an earlier post), reinstalled service pack 2 to the point where I had reinstalled the XP but wait for it the screen flashed before I even installed the video driver!, so opened up and had a look inside at the nvidia video card and found the same problem as mentioned in post 191 with the capacitors slightly raised with a residue! So I suggest even if it’s a conflict with the OS and video cards be brave and have a look inside, it will save you frustration and time if that’s the problem if not install new drivers! but it does baffle me as to why my pc only crashes during WMP and when it requires extra graphical bluagh.. you know what I mean. By the way my pc is 3-4 years old, gonna check out the prices of graphics cards now! lovely!!!!

    the only thing I had to do differently was start my computer in normal mode before I installed the update, don’t ask why because I don’t know…so far no more problems! thank you so much for this site…I thought it was a Virus…thank you thank you thank you!

  • Posted by: Fred Flintstone | November 10th, 2007

    Ok, after about a week, I still seem to have the same problem. But it only happens every few days unlike before where it was happening every day.

    I guess the moral of this story is never EVER buy Nvidia graphics cards. I’m going to buy myself a new card from some other company.

  • Posted by: Paul | November 12th, 2007

    Here’s another take, for those who are so spooked by Nvida, Microsoft, et al, that you don’t dare switch drivers: entering in Safe Mode, I found that reducing the Harware Acceleration (Control Panel-Display) to zero fixed it, i.e., I can boot normally now. Don’t know yet what the impact of zero acceleration will be on applications….

  • Posted by: Fred Flintstone | November 19th, 2007

    After the most recent Microsoft patch update (for Windows XP SP2 – Mid November), my problems seem to have completely gone away and I have not bought a new graphics card.

    My hunch is that a previous Microsoft update was causing my earlier problem. If I didn’t know better, I would probably say this might be a ploy on the part of Microsoft to rip off consumers by tricking them into thinking something is wrong with their computer to get them to purchase a new computer, hardware or upgrade to Vista.

    Piece of crap Microsoft and those money grubbing a-holes who work there!

    This is NOT just a dell issue. Dell might have known about the issue before they released the series of computers, but it’s not limited to Dell. I built my boyfriend’s computer with my own two hands bottom up. He is having the same problem. I haven’t figured out exactly what it is yet. I’m taking it one step at a time to figure it out, but it helps that there are a lot of people with the problem and with many solutions. Good luck to everyone.

    My Dell Dim4600 giving BSOD with nv4_disp error. Tried updating drivers as per this article. Didn’t fix it :( Now I think it could be hardware. G card freed, probably?

    I have an integrated GeForce 5200 on the motherboard. Can I upgrade the G card to a newer one? Will there be any issues with replacing the G card since it is on the motherboard?

    I’m wondering if it’s a memory issue? I’m running an XFX Nvidia GeForce 7900 GS graphics card (256MB) on a Dell Dual Core 1.86GHz (1GB RAM). I’m getting nv4_disp BSOD crashes with Crysis, but I can see it’s happening when the game graphics are working hard – typically when I use the cloak or night vision features that require serious graphics grunt. I’m going to upgrade the RAM first to 3GB and see if that helps, and if that fails I guess it’s time for a more powerful video card …

  • Posted by: ShivK | December 15th, 2007

    Aftre this fix I now have a very small font and small size graphics problem – can anyone help?. I was getting the ‘device driver got stuck in infinate loop – file typr nv4_disp problem, and Blue screen of death. So I tried the fix suggested. I have a 6 year old PC ( that has run perfectly for 6 years – am I lucky or what ! ) with a NVIDIA GeForce 4 Ti 4600 driver. I am using windows XP , service pack 2. I couldn’t find my GeForce Series 4 driver listed on the NVIDIA dowwnload menu, so I downloaded the latest update – the GeForce 8 Series 800 Ultra. My PC now works perfectly, except that the font size and graphics are really small, and I can’t adjust them. I am suspecting that the GeForce 8 series download is not compatible with the Geforce 4 card on my PC. and I can’t download a compatible update. do you think I am right – is the asnswer to upgrade my hardware?

  • Posted by: SdrahCir | January 5th, 2008

    I had a combination of problems. My setup was working fine for about a year before I got the error message. First thing I did was uninstall the nvidia drivers while in safe mode and manually deleted all nv graphics related dll’s. I noticed that I had both old and new drivers loaded in memory even after doing this. Windows likes to lock down drivers so that when you try to uninstall them, they will not and stay loaded. Even if you manualy delete them, XP will re-install the drivers from the system restore cache. Trick is to turn off system restore and delete all of restore files for your drivers so it cannot reload them. Once removed you can install the WHQL drivers and check the nvidia control panel to see what version of the drivers are loaded. If done right you should only see the latest version and not mixed.

    Once that was fixed I noticed less error messages but they still happened so I did a RMA on my card. New card lasted a week before getting the same message again. I then ran memtest86 for 6 hours knowing there was nothing wrong with my new card. Turned out one of my 1066MHz memory modules was going bad. I put in my trusty spare 800MHz Dominator modules and guess what, no errors on memtest86 and no nv errors for about a month now.

    To sum things up I had these problems:
    1. Sloppy driver install/removal, old/new drivers mixed and loaded in registry.
    2. Failed component on Video card…probably memory or capacitor.
    3. Bad memory module, I know the model and brand I’m using has this problem…3rd time I had to RMA in 10 months. *coughcoughballistixtracercough*

    If you’re thinking I have a cooling issue I don’t. My system temps never gets above 35ºC while under full load and my power supply is 1000W hooked up to a APC BR1500LCD.

    Thanks for this information! I have a Dell 4550 with NVIDIA GeForce MX 420 and when I try to download Windows Updates, I get the BSOD when the computer restarts. This wouldn’t be a problem (I just wouldn’t install any more Windows updates) except that my computer will occasionally freeze to the point that even turning it off won’t work – I have to unplug it to escape the loop and shut it down. Fortunately I have always been able to use Last Good Configuration to get things back on track. I will definitely try and install updated NVIDIA drivers – thanks again!

  • Posted by: jelly_jacket | January 12th, 2008

    My computer froze up yet again yesterday so I decided enough was enough. Downloaded the new drivers and installation went off without a hitch! Was glad I had read this forum because I had the same HUGE images and text (low resolution) issues as some of you after I had uninstalled the old drivers. Easy fix once the new drivers were in place. Thanks again! The true test will be when I try to download Windows Updates. Fingers crossed :)

    Two words – heat and power.

    My machine was unstable and hit BSOD in nv4_disp over and over. I checked the PSU and found it under powered for the combination of processor, hard drive, DVD, and graphics card so I changed it. The BSOD now happened much less frequently, but still sometimes. I noted the temperature in my office was higher when the BSOD occured, so I upped the air-con and everything was ok. Now, an air-con is pretty expensive to run so I added a low speed blower to the case (one that goes space where a PCI card can go) and set the air-con back to normal. Without the blower the CPU hit 63C, the Chipset hit 60C and the Graphics card hit a huge 77C.
    With the blower the CPU never goes over 51C, the Chipset gets to 41C and the Graphics card 49C. And guess what – no more BSOD.

  • Posted by: Aeomer | January 19th, 2008

    … one final note about power. PSUs get slowly less efficient over time. Maybe th 18month limit people mention is indicative of PSU not putting out the power it once did. Just a thought. Before buying a new PSU, get the old one checked (though that may be more expensive than buying a new one ;-) )

  • Posted by: happn_babe | January 21st, 2008

    THANK YOU. That problem was driving me out of my mind. This solution worked, though I had trouble figuring out which driver worked for my hardware. Eventually, I got what I needed, but you might want to go to NVIDIA first to have it suggest a driver before you go into Safe Mode. The NVIDIA site cannot scan you in Safe mode to make suggestions.
    Thanks again, you were a life saver.

    I have had similar experiences with my Dell 390, NVIDIA Quadro FX 3500, and my problems started to happen when I adjusted the antialiasing settings, switching it to manual instead of “Application-controlled”. My computer had a fresh install a month ago, and I never had any problems prior to that or before I “yanked” up the antialiasing settings to 4x.

    See your Display properties, and under the NVIDIA settings look for “Performance & Quality Settings”, and then see if the Antialiasing settings are “manually” controlled. Consider turning on “Application-controlled”, and see if that helps.

    I have a Dell Demension 4600 with a NVIDIA GE Force FX 5200. I also had the Blue screen for nv4_disp endless loop, a secondary condition was my screen would go black for 1-2 seconds on every screen refresh. I attempted the driver update suggested first, but still had the problem. I then looked at the Capacitors on the board and found three to have convex tops and some white powder residue. I called DELL and found that I had an extended warranty which would expire in July of ’08 (WOW). I explained the problem first to an uninterested DELL Helpdesk person. Hung up and called again (got and interested Dell Helpdesk person) and explained all of the above and that the Capacitors were definitely blown (I wasn’t sure but I acted like I was). Within 30 minutes after calling DELL they had a replacement card being shipped to me. Received the replacement card and installed in my PC. This fixed my PC. Christopher Thanks for this info. I wish I hadn’t read every single entry before resolving, but they gave me enough confidence to be sure I knew what the problem was.

    Most people who have tried the steps outlined above continue to have the nv4_disp blue screen of death error message. However, after 3 to 4 days of solid research on the problem, I came across a registry edit in another forum. I started a thread at the nvidia forums, which you can access at the following URL:

    All my BSOD errors and stalls in loading time with games completely vanished by following the registry edit in this forum. Just remember that changing your registry settings incorrectly can harm your computer. Hope this helps everybody!

    I had this issue on a DELL Dimension 8250. After reading through the comments, I did not see the answer to why this happens so I am going to tell you why it happens. This issue is primarly caused by a Microsoft Update that conflicts with the older versions on Nvidia Software and Drivers. My advise to others to prevent this in the future is to make sure your device drivers are all updated before doing any Microsoft updates and to turn auto update OFF so that you know when a Microsoft update causes a issue like this in the future.

    I have had an emachines T6528 on XP for 2 years.

    I first had trouble with the cd/dvd drive button not opening a month ago. I have to try several times to get it to open.

    Then I got the blue screen saying “device drive stuck in infinite loop” (nv4_disp) a week ago.

    then i restarted several times to get it working again, in safe mode, installed the NVIDIA drivers and thats when my audio and modem went out.

    in addition to that issue, I have to restart several times to get the computer to boot.

    Suddenly, neither the EMU audio card nor the modem will show up in devices.

    I flashed the bios and they showed up and reinstalled BUT after a day they disappeared again!

    Also This system has an MSI mobo with onboard sound… which is missing also!

    I tried reinstalling the drivers to the onboard sound but it did nothing.

    no audio and no modem.

    A tech guy told me its my motherboard but is there hope?

    I had the bsod nv4_disp infinite loop after reinstalling windows on a Dell 4550. I then ran windows update for sp2 install — that is where the problem started. I followed the instructions in the article except: I used belarc advisor to get a system audit report which listed my video card details for me. Then I went to the Nvidia site and downloaded the driver for my specific card (GeForce4 MX 420). I simply installed the driver while I was still in safe mode so that I did not have to worry about anti-virus interfering with the installation. Then, before rebooting, I read the comments here and got to number 170. That comment helpd me I am sure. I had automatic update turned off, so I ran windows update manually and there was an older driver that WU would have installed had I not de-selected it and chose to not display that update again. Hope this helps someone. Thanks again for this article, I am glad I found your site.

  • Posted by: Xtina | May 9th, 2008

    Similar problem. My computer kept crashing and rebooting directly to the screen asking how I would like to start windows (safemode, last known config, normally…) so I would go with last known configuration and things would work. No BSOD. Well, I had another crash yesterday and this time it rebooted and all of the text on screen appeared to be jumbled and miss spelled. Very odd, EXAMPLE:
    Sadd Mode
    Sadd Mode whth Networking
    Sadd Mode whth Coml`nd Prolpt

    I thought it might be a virus because I couldn’t get into safemode (a bunch of lines of code about drivers popped up) so I reboot(not knowing what i am doing). That is when I got BSOD with the error of nv4_disp. I had to find another computer to research this and found your info. I tried it, successfully got into safemode (although it was “Sadd Mode whth Networking” and have partially solved my problem. I uninstalled the drivers I had for my GeForce3 Ti500 and reinstalled the new downloaded from nvidia. I no longer have blue screen error but I am stuck in what looks like Safemode but my computer is running normally. My display adapter now shows Video Controller(VGA compatable) and it is not working properly. When I tried to update, it did, then i crashed and it restarted and is saying it is not working properly again. So, my questions;
    1.Any further suggestions
    2.Should i try getting a new card, i know mine is OLD
    3.Any light to shine on the misspelled text? I took photos of the screens if you would like to see what I mean.

    I’m sorry this is so long.

    Boot your computer into Safe Mode w/ Networking. For Windows XP users, this is accomplished by pressing F8 repeatedly when your computer is booting up. You will be presented with several options. Choose “Safe Mode w/ Networking.” This will boot Windows XP into Safe Mode, but you will be able to browse the Web….. then go to the device manager right-click on display adapter update driver, click on ( yes this time only) then click on install driver automatically ( Recommended ) and click next ( make you have access to the internet ) the machine will search for the driver and download and install it itself …reboot and the problem is solved… that’s how i solved the problem though

    Had the nv4_disp endless loop problem show up on my Dell recently. After spending a few hours messing around with software/drivers, I checked the graphics card and found several bloated capacitors. After replacing the board, PC works great. Got a great deal at Fry’s Electronics. An e-GeForce FX 5200 card was $55, but has a $40 rebate good through 9/30/08. Good luck to all.

    Tell me this hasn’t hapened!

    It has!!

    Same problem – Toshiba Tecra M2 four years old. BSOD – and while it is flashing blue I read about the nv4-disp infinite loop.

    Google nv4-disp and here I am amazingly perturbed that this has been going on for over two years.

    What do you do with a four year old laptop? Can’t spend serious dollars for a new motherboard; not financially effective.

    Unbelievably, just a few days ago I was looking at the new Dell Studio 17 – perhaps my current Toshiba caught my vibes and said “I’ll fix ‘em”.

    Anyway, any suggestions?

    Does the generic nvidia driver work for this notebook – running XPSP2.

    I did the download – 81.98_forceware_winxp2K_english_whql.exe – on my Dell XPS 1330 and then put the file on a memory stick.

    Do I boot in safe mode, control panel and remove the nvidia driver, and then install this file OR is this the wrong driver for my Toshiba laptop?

    All help and support appreciated.

    Cheers for downunder!

    I have run into the problem that everyone else has with the driver and so far the solution that has worked is to run safe mode and uninstall the driver saving you to reinstal your operating system.

    I’m elated – this worked, just like you said, in about 10 minutes!!! I noticed that lots of other people have found Dell support inordinately time-consuming – my sons told me about googling the “error.” My Dell Dimension 8300 is now going on five years old and hanging in there – you’ve given it a new lease on life. Computers need to cost less to own and operate per year, like my washing machine! Anyway, thank-you, thank-you, thank-you!!! (got this site bookmarked…)

    Paul @ #49 is my hero. I could not find a replacement card that did what I wanted it to do. Then it hit me. Paul said capacitors were popping. I examined my card and found three with domes on their roofs. I went to Radio Shak and bought some replacement capacitors, the biggest capacity they had ignoring the voltage. I replaced the domed caps with the relatively large Radio Shak caps and I am up and running. It is not too easy to melt the solder and resolder the new caps as they don’t make boards like they used to, but it is worth the effort.

    I see that several members wrote about blown capacitors. I wish I had come across them sooner. It feels great to repair my video card. This solution took some time to sink in.

    My problem is solved? Yeah, right, I just downloaded the new drivers and THEN it started crashing.

    Googling for this I see its a problem way back to 2002! It’s amazing those amateurs can’t fix their crap!

    I am using PCI NVIDIA 7300 GS. Its only 256 MB. after experiencing the nv4_dll problem, i downloaded and installed the latest driver from nvidia website
    (NVIDIA Forceware 185.85 WHQL XP)
    After installing the latest driver, i still have the BSOD. I booted up on safe mode/networking and checked the settings of my video card adapter. It is being detected as 512 MB!!!!! I think this is the reason why I still have the BSOD.

    Had the same prob with the nv4_disp error. Tried the five steps but got “no supported hardware for drivers” at step 4, Restarted computer anyway and it seemed to work, but after trying to reset my screen resolution, the computer just restarted and came back to the black error screen. So, I shut down computer, swapped the monitor, and restarted. That worked! Didn’t have to do anything else. It just booted right up as normal. Hope this helps someone.

    hey – thanks for the help. i’m having a problem though. here’s the link of the new driver i downloaded from NVIDIA.

    When I run it (it goes into the install shield and starts extracting files, etc) – but it gives an error saying there are no drivers found compatible with my hardware. I have a Dell Inspiron 8600.

    I tried both the diver files listed above.

    Please help!
    Thanks Bruce 303.204.3154

  • Posted by: wayner | January 12th, 2010

    Bruce, I was getting the same message. Go to the Device Manager again and click Scan for New Devices.(Next to the yellow question mark) It should find the Display Adapter. Once it’s listed again, you can update the drivers by running the download. Everything is back to normal for us.

    Good luck, Wayne

    I have a Dell Latitude D630 laptop with NVIDIA Quadro NVS 135M driver. Installed new driver and thought all was good but then it happened again. On my computer it happens after hours of use and then most times I cannot even get to point where I can go into safe mode. However, if I let it sit for a while (say half hour) it boots fine. No unusual heat noticed. Not sure if this is the same problem as everyone else or if I have a hardware problem.

    I used to have same problem, and I try to solve just like u said, but unfortunately I didn’t solve it that way. And I’m also try every other solution. But I only needed to instal Malwarebytes Anti-Malware to my comp and scan system. Malwarebytes Anti-Malware was found about 24 worms and somekind virus. After cleaning all this s**t my comp works perfectly. Try this way.

    It’s amazing how long this problem has been alive! Never had any trouble with my EVGA GeForce 7900 GS running in Windows XP SP3… until I downloaded and installed the latest driver from the NVidia site. Then, BSOD (nv4_disp.dll) every 30-60 minutes.

    I uninstalled the new driver, ran a registry cleaner and installed the next earlier version. No change. I repeated this process for each successively earlier driver going back two years with no luck.

    As so many folks have suggested, I got a copy of the last free version of Driver Cleaner and ran it according to their NVidia instructions. It found and deleted stuff from earlier driver installs that the registry cleaner did not. Then, instead of installing any of the versions of the NVidia driver I had downloaded, I used Windows Update to find and install the NVidia driver. Now everything is stable as can be.

    So, for me, not a virus, not malware, not a hardware problem. It was residual flotsam and jetsam from previous driver installs. Thanks everyone for sharing your experiences. It was helpful in keeping my downtime to just one evening.
