OpenGL problems

Ok, I have some problems whenever I run a OpenGL program in Fullscreen mode. It's has some sort of glitch where the rgb kinda "seperates" and creates like 2 or 3 images where one is red and the other is blue. I have attached some pics below. Take a look. The only good thing about this glitch is that I can put on some 3D glasses and it will look 3D. The real reason why I have a problem with that is because it causes a MASSIVE slowdown in my games (particularly Doom 3 and Quake). This sucks. Any ideas? My PC specs are below (PC #1). Thanks.

EDIT: in windowed mode, everything is ok but still slow. And some OpenGL apps like Snes9X GL won'r run at all :hdbash:
