Alright so heres the deal :

My mom goes to boot up her computer today, it goes to the WinXP loading screen, monitor goes black like its loading the welcome screen like normal, never comes back on, monitor then shuts itself off and computer reboots. I come check it out, windows is saying the drivers for her TNT2 are causing the system instability. I'm like okay, so I boot up in Safe mode, download the newest drivers from nvidia for her card, yadda yadda, still does the same thing.

My first thought was that the video card was dead, but generally when one dies, you get no picture at all, and the card is recognized by windows, has no IRQ conflicts, no driver problems (visible), but once it tries to go anything higher than 640x480, the screen flashes to a command prompt looking screen, then back to windows and tells me that windows has detected a device failure and has fixed it, and to reboot to restore functionality.

I have formatted and reinstalled windows twice now, still does the same thing. I have asked 2 technicians on this subject and they claim to have no idea why it would do that. I'm pretty certain the card is borked, but I dunno why it would work in safe mode, but not normally.

Like i've said, i've tried new drivers, disabling acceleration, updating the chipset inf crap for her mobo to support AGP, everything I could think of, and nothing. It will boot up normally once the card is uninstalled and rebooted, but once the card is installed again (WinXP auto installs new hardware), when you reboot, poof black screen, reboots into an infinite loop.

Anyone have any ideas?

In safe mode, it is running 16 colors, 640x480, at 60hz. Windows will likely set the card at 256 or 16k colors when it loads the drivers and may alter the resolution and refresh as well. If you have already tried new drivers (assuming you didn't leave any old drivers on it), I would guess perhaps the mem on the vid card is failing.
