So I just got a new computer and whenever I play a game a weird horizontal green line appears and a thick green line appears vertically. It probably has to do with my video cards (2 Nvidia GeForce 6600 GT's), i'm guessing there's an option to turn them off, but I can't figure it out.

Someone please help me!
