I just put together a new computer and was installing my sapphire 9700 pro from my other computer, I swapped them from old computer to new computer a few times. So then when I went to boot up the new system all I get is a white screen with little colored squares that flicker. Is my video card fried? I tried installing it on different motherboards/monitors and it does the same thing so it must be the video card. Is there anyway to fix this or is it a physical problem?
