Can't install new drivers for graphics card

April 16, 2012 at 12:30:32
Specs: Windows XP
Out of nowhere a couple days ago, my laptop started acting up - the startup screens were all screwy and I got a blinking green screen of death, which is a first for me. What I saw of the message told me there was a problem with the file nv4_disp, which I found is related to the display. It seems to be a fairly common issue and internet instructions advised me to boot in Safe Mode, uninstall the card, then start up again normally.

For the most part, the laptop is behaving. The screen is still grainy and the overall display is running a little slower (like major lag when scrolling). I downloaded what I think is the "updated" driver from 2006 from for my card (NVIDIA GeForce Go 6800) and tried to install it. I was told the driver is a multi-disk program and that I need to insert the last disk. Which I obviously do not have because the driver is from a download and not a disk. I followed Dell's instructions and they don't say anything about needing a disk. Do I need the disk that came with the laptop?

So this is where I stand. I don't know how to update the driver when I can't even get it to run. I've tried going to My Computer > Properties > Hardware > Device Manager and updating from there, but I always get told the drivers can't be found. I don't know what to do now and it's getting irritating having to start up, get the green screen, shut down, boot in Safe Mode, uninstall the already uninstalled card, restart and boot normally every single time I want to use my computer (because no graphics card seems to mean no standby/hibernation either).

Can someone offer any advice, please? From what I've been reading, this seems to be an issue with my particular laptop model, which is a Dell Inspiron 9300. The file I downloaded is called R121867.exe. Should I uninstall the drivers I have or simply update them?

ETA: From another website, I also downloaded a file called nv4_disp.inf which included instructions to use it while installing the new drivers. I got a message saying that the software had not passed Windows logo testing and that it shouldn't be installed because it may impair or destabilize my system. Don't know if this is important, but just in case, I wanted to add it.

Here is a good program that removes all your nVidia drivers

Normally all drivers for a manufactured system should come only form the manufacturer's website, but with graphics drivers you can and most probably do, get the driver form NVidia's website. Go into Safe Mode with Networking and go to and search the driver for your graphics engine, go to Device Manager and uninstall the graphics from there, then install the driver you just downloaded (just open the file) and restart in normal mode. This should complete the hardware reinstall with the new driver.

You have to be a little bit crazy to keep you from going insane.

Thanks very much for your help. Also, I went to NVidia's site and tried to look up info on my card, and the site told me there were no drivers available for my system specs. Also I tried the "automatically locate the right software for your product" and just kept getting told the search engine wasn't available.

I've read that only offers drivers for desktop computers whereas I would need to go to the manufacturer's website for a driver for a laptop. Is this true?

I also tried using that .INF file and it messed stuff up a lot, so that was a no-go too. I'm just not sure if I need the most recent drivers, something besides the one I've got OR if I should uninstall my current ones, sweep my registry clean, and then re-install those same drivers. I'm not finding a whole lot regarding updates for this particular card.

Not to mention I've got a horrible internet connection that does not like to download large files - usually anything above 5 MB will either stop for no reason or download improperly and end up corrupt (which is what happened with the drivers I downloaded earlier; they couldn't be unzipped because the file was messed up).

Well, I would uninstall the drivers that you have, use the driver sweeper to remove all the leftovers, reboot and install the newest drivers from Dell.

That is the safest way to go about it.

You also may want to update your BIOS because VBIOS updates are included.

Lets just get this taken care of and see if this helps, because you are not going to like the next options.

Because about half of all the 6000 chips ever created were made with defects that only shows up after multiple thermal cycles.

Haven't gotten the drivers yet (hopefully will get them tomorrow as I'm going to use a friend's actually good internet), but I've been seeing some things here and there about this error being related to a virus. I ran another malware scan again and just got a couple tracking cookies here and there - no viruses. I'm confused - is it a software issue or a viral issue? Or both?

My computer has been moving abysmally slow since this nonsense started (though it's been starting up faster, for some reason). I mean things like needing to "End Now" random windows because they don't close on their own, and Task Manager getting disabled. I don't know if that's normal for this particular issue or if maybe it's another issue entirely (like a virus my anti-virus software does not recognize).

And I'll be totally honest - I have no clue what BIOS is, but I will find out and see what I can do to update it.

Also, I found this - someone claiming to have found a fix for the infinite loop issue when other options have not worked. It's a beta patch. Should I keep this in mind or does it look spammy?

You know, I missed where you said that the files that you download get corrupted. You maybe having a memory problem. So first off, download memtest and burn it to a disc and run it

So your computer has a daughter card that is known to fail. I have repaired many of these cards they typically overheat and fail.

This is a great writeup about the piss poor engineering at nVidia

I do not recommend updating BIOS unless you have a specific problem that the new BIOS is listed as fixing. A failed BIOS update can leave your laptop good for nothing better than a door stop. If you DO need to do an update then make sure your battery is charged AND your power is plugged in.

The fact that you cannot open your Task Manager means that you either have a really bad infection or a badly corrupted system file, probably caused by an infection. If you can get into Safe Mode with Networking, then download Malwarebytes, install and update it, and run it. Remove all it finds. Restart normally and rerun Malwarebytes. If you have trouble installing Malwarebytes due to the infection then change the name of the installer (something like 'mysavior' or 'MyMB' will do, but leave the extension the same) and when the installer asks you if it is OK to install and the name of the file and the name of the folder, change both as well (the program needs the .exe extension). If you cannot get into Safe Mode or cannot install Malwarebytes or cannot remove the infection, you may end up wiping the drive and reinstalling XP entirely so back up important files to an external drive (scan them before copying them back later) since some Root Kits can be very hard to remove once they get dug in well (which is why they usually begin with causing small problems initially so you will ignore them for a while).

Oh wow, didn't know the cards got all screwy due to heat issues. My laptop does get pretty warm (for many years I had it on max brightness and the core temp could get really hot). But with the help of SpeedFan and taking the brightness down, I got the interior temperatures under control. Possibly too late.

Got the drivers via and unlike most cases I've read, it installed without a hitch. I've still got the dots all over my screen, but I have an actual blue screen rather than a green screen, so I think it's gotten a little better.

However, now I'm getting an error for the file nv4_mini.sys - so same bloody display issue, but different file. I did not clean the drivers off beforehand, but I'm doing that as I type. There was an error message about an "unexpected exception" but I chose to continue and the cleaning is still going on and I don't know how long it's supposed to take. Anyway, once this is done, I'm going to try reinstalling the drivers and the graphics card.

Thank you all very much for your assistance in the matter. I hope once I get all this done, I can come back and say the screen's behaving a little better.

Got some updates after using the advice offered (most of it).

1. Downloaded and ran Driver Sweeper on the NVidia Display drivers. Removed everything but the four registry files no matter how many times I tried to get them off. Should I remove ALL NVidia drivers or just the display ones?

2. Downloaded, updated and ran Malware Bytes. Removed 10 infections. No difference.

3. Re-installed new drivers. No longer getting the green screen - now it's just a blue screen, but now the issue is with a file named nv4_mini.sys due to "PAGE_FAULT_IN_NONPAGED_AREA.". So the issue with the display remains, but now it's with a different file. I'm guessing the entire driver is the issue rather than just one section. I can still boot in Safe Mode, but not normally.

I'm reading that if I replace that file, it will fix the problem. The thing is I did that with the nv4_disp.dll file and it made everything worse, so I'm not sure if I should try it again with the entire driver.
