Ok i just got a 9600gt card to replace my dual 7600's. Now when i boot the system i get redlines verticaly, this last until windows starts then windows is fine. when i load world of warcraft i get theese same line unless im in windowed mode. Any idea? I know the card is designed for a pcie2 slot but says it can run in a standard x16 which is what i got. I have 500 watt power supply. Also when i start the computer the fan on the graphics card is load as hell but once it gets into windows its gets quiet.
