its not even installed right now. I did one final thing someone else found fixed this with his GTX 470. reinstalled Vista. I havent gotten everything else installed yet, just the OS then went to bed. I'll let you know if that fixes it for me.
EDIT - Vista didn't fix it, it was even worse. Back to Win7.
