Well, I was given a computer with a a8n5x motherboard, 2xgigs of corsair memory, a radeon x1900 xt, and a 450w coolmaster power supply. When I got it, it had no display so I tried replacing the video card, but still, nothing. So then I got a new motherboard, got no display and figured out that the video card was f**ked up. I went out and got a nvidia 8600 GT OC. I've just about given up but I want to know if anyone has any clue as to what else could be wrong, maybe a messed up power supply or processor? The new motherboard I use is a a8n-sli se.
