First of all, my background: I'm a grad student, total geek, and fairly computer literate (i worked as a network engineer for 2 years before returning to school). anyway, i tend to be very wary of tech support as i am generally several steps ahead, and get aggravated by their lack of knowledge.
My NVIDIA GeForce4 440 Go display adapter started giving me trouble last week. I went through the XP troubleshooter, updated drivers, updated bios, unistalled, reinstalled, and nothing i did seemed to work. (see Mindy3333, i was experiencing very similar things). I found this thread and began to troubleshoot based on suggestions above. Based on my troubleshooting, i came to the conclusion that it had to be a hardware issue, because nothing i tried worked. Finally, i called Toshiba support (my laptop, 5105-S701) is still under warranty. They told me to run a system recover; i told them to take a flying leap.
Luckily, i ignored their suggestion, did not reformat my hd, and took my problem to a great repair shop. Within 30 seconds of walking through the door, they were able to tell me the problem. They took one look at the laptop and said, "NVIDIA, right?" They explained that they have had several laptops (Satellite 5105 series) in with the same problem and it all stems from overheating the video card. The damage accumulates over time, so most of the computers coming in with cards that have completely failed are ~ 3 yrs old. They were able to show me the internals of a Satellite laptop and how the video card rests on the CPU forcing it to take the brunt of the heat output. They had several in for repair, but no ETA for the refurbished cards. They said it had been averaging 3-4 months to get a card in, and suggested that i consider buying a new laptop.

I have a question .. why does the nvidia driver crash, but if we use the generic vga driver it doesn't?
Well, if it is purely a hardware issue, the vga driver shouldn't work. If you are able to get the vga driver to work, then chances are your card hasn't completely crapped out. In my experience, i could get my laptop to behave for 20-60 minutes and then it would crash again. at the time, i didn't equate the failure to how hot my computer was getting. Also, if NVIDIA is not going to support this card anymore, chances are there will not be appropriate NVIDIA driver updates for it.

Trish, if it is caused by overheating, wouldn't getting the laptop's internals cleaned help? For example http://www.hardwarea...opic/23605/?o=0
If there hasn't been too much damage to the card, then this could help out a lot. it is not likely that cleaning the internals will recover the damage that has been done, but it could help your card last longer. I think that part of the reason my card lasted as long as it did is that i don't leave my computer on over night, and when it is on, i keep the fan running at all times. (i have a great fan utility on my laptop that lets me force the fan on)
