8800 GTX NV_DISPLAY error, can't play anything :(

[ReTiCuLeX]

Hi all, I had everything working...... ran 3Dmark, etc.. Now I go to launch Rainbow Six Vegas or Direct X Display tests and they both fail, giving this error, or rebooting the system if it goes to full screen at all.

I can see the cubes in the test in the DirectDraw Test, but not Fullscreen.

Sorry for my Grammar, I'm really tierd. Hoping I can find an answer for when I wake up.

Thanks,
