Hello, I been having problem with graphic problem for a while now. I'm on my third graphic card now, the first graphic card i had on it was an Ati 9700 pro, secondly was the Ati 9800 pro which i broke while changing the heat sink. Now I'm using another Ati 9800 pro and still having problems. Everytime while playing games my computer my screen would go blank, and this happens with all three of my cards. Is there a way to fix this? Computer specs. Asus P4s8x P4 2.4 533fbs Ati 9800 pro 1gb ddr 2700
