Big OpenGL Prob...please help

Any game that I try to play or any screensaver I try to use that uses OpenGL gives the same result (double vision of everything, with some flickering)… I’ve tried several different Nvidia drivers with no change. When I run directx diagnostic test, the 2nd test for “directdraw” doesn’t run (bouncing box in full screen)…any suggestions would be greatly appreciated.
