I am running a AMD Sempron 3000+ processor and one of those Gigabytpe Triton Mother boards. The Video card is a GeForce 6600 LE. When I load the computer everything is fine and it plays correctly. However, after a few minutes the computer will give me a black screen for a split second before freezing up on me completely. I have looked and I thought it was perhaps an AGP driver that needs to be updated, I really have no clue though. The computer was just built and I salvaged the hard drive, I used to run a GeForce 4. However the hard drive was reformatted. Thanks in advance!
