I have an ECS P4S5A motherboard along with a visiontek gf4 ti4200 or 4400, dont know, was given to me for free. Anyway after i installed it, i turned on the comp. Right after the windows xp splash screen loaded (the one where the blue bar goes left and right), the screen turned blank/black and nothing else happens. I waited a few minutes but it remains black. I installed the graphic card to another computer and everything booted up fine, and the graphic card worked fine as well. any idea on what the problem would be?
