Hey, long time reader, first time poster. My friend directed me here to see if I could find a solution for this issue.
Basically, my NVIDIA GeForce 9800 GT driver is not working. Or that's what my computer is telling me anyway. I'm running a Dell desktop (about a year and half old) with Windows Vista 64-bit home addition. On Thursday I purchased a Microsoft Lifecam VX-5000, installed and used it with no issue. I put the computer to sleep, went to bed, and awoke the next morning to find my desktop complety pixelated on start up. Looked a bit like a Picasso painting. Obviously this is bad.
My desktop will often lock up or freeze, or pixelate. Sometimes the screen will flash or go black, and that won't go away until I re-start.. I have reinstalled the latest driver for Windows Vista Home Premium 64 without success, I also uninstalled the device software from the computer and allowed windows to auto reinstall upon restart. This has not fixed the issue. I often get this error message: "Windows has stopped this device because it has reported problems. (Code 43) Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available." I'll also usually get this when I'm just surfing the web: "nvlddmkm stopped responding and has recovered" this pops up after the screen flashes and pixelates, then goes back to normal.
I assume the card is dead. I've noticed when starting a game the fan will not start, which then crashes the game and pixelates my display. Is this a hardware issue or a driver issue? Obviously the fan not starting is a hardware issue, but is the fan failing because of the driver? I had no problems before I installed the Lifecam VX-5000, and I'm convinced this is what caused the issue. I've un-installed all traces of the Lifecam and returned it, but yet my problem persists. This graphics card is only a little over a year old.
I'm hoping it's a software issue and not a hardware issue, but I'm not holding my breath. If a replacement is needed, what's a comparable card I can purchase? I've got a few games that are pretty intense graphics wise, so I need a card that can still play them.

I gotta say though, I think your is most likely dead. I had the same thing happen to a 7900GT a while back. Crazy pixelation from time to time, then eventually Windows crashes. Popped in a 6600GT from a different machine and everything was fine, i.e. it was definitely the card. But try the drivers before you break down and buy a new card.
I was hoping it was just a driver issue, but I'm 100% sure the card is dead. Sucks, but what can ya do. But I know the 9800GT runs hot and doesn't have the longest lifespan (still expected it to last longer than a year and half though). I should have just bought the computer with an ATI to begin with. I have a Radeon 5550 on the way, which should actually run a bit faster than this one. Here's to hoping it doesn't crap out on me the second the warranty goes.

Suspect it killed my 8800gts, it had problems very similar to what you described before finally stopping.
Actually, the card I ordered is from XFX, so that won't be an issue.
I heard about that too, but I don't think it was an issue for the 9800GT. I could be wrong though. Either way, the driver mentioned in that article isn't the one I'm using, I have their latest driver that was released in July. So unfortunately I can't go yell at Nvidia about this one.
New card is a few towns away, so I should have it tomorrow.
Replacing the card made the problems go away. Since one of said friends also had a laptop die (because of the more-well-known laptop chipset ticking timebomb of death problem), pretty much discouraged us from buying NVIDIA again. Especially since all the card failures came at a time we a) didn't want to buy new video cards and b) video card prices were artifically inflated due to demand.
Here's the thing, my fan is stuck at 30%, and that must be what the problem is. It won't increase speed on it's own, only when I manually do it. The second odd thing I'm noticing is that as I type this, my gpu temp is slowly creeping up, even as I'm just surfing the web. Once it hits 72 is when my deskstop starts flaking out on me. But my fan never kicks in above 30%.
So what could be causing this? Is the card even the problem, or is it something worse? And is it normal for the temp to keep increasing if I'm only surfing the web?
