My brother just bought an EVGA 8800gts 320mb video card. I installed it for him and it will boot into Windows just fine. When I run any game or 3dmark the screen goes black and the computer locks up. After a few minutes it reboots. I've tried formatting and reinstalling Windows and using different drivers from Nvidia with the same results. At this point, I'm thinking it's time to RMA the card, but I wanted to get some other ideas first. The system specs are:
Athlon 64 3500+ 939
Asus A8N5X
2GB Kingston DDR PC3200
XCLIO Goodpower 500
