I put in a new video card in a older Dell, for my wife where she works. It's a Pentium 4, a gig of ram, and a agp slot, and she was using the onboard video. She got 2 Evga GeForce 7600GS 256MB 128-bit GDDR2 AGP 4X/8X cards.
I 'm upgrading 2 machines for her. I disabled the onboard video and installed the card.
The problem is that after about 2 hours after installing, the system would momentarily lock up and the screen would go black. Works for about 1 or 2 minutes and it does it again. I got the latest drivers from Nvidia. and still the same. Even tried a new monitor, no luck.
Thought the card might be bad so I tried the other card and still doing the same thing.
Anybody got any suggestions?
