I'm using vista ultra, every time I go to full screen it works for a few seconds then goes black. It keeps coming on and off till I hit ESC then I get the message Display Driver has stopped responding and has recovered.
try looking at your temps for your graphic card.
better yet download rivatuner which you can manually adjust your fan speeds so they will keep the card temps down. http://downloads.guru3d.com/RivaTuner-v2.09-download-16... you can also save fan profiles for easy ability to switch your fan noise down while surfing the web or crank the fans up while playing games at 65%
