Re: GTX 280 - a problem
When I reinstalled Windows Vista recently I had a problem with the screen flashing when I clicked the audio control panel window for my X-Fi. I have no idea why it did this but it was something software related for sure. I think I just rebooted and it went away, though I may have reinstalled the driver. I can't remember for sure.
I'd try uninstalling the video drivers completely and installing the latest version again.
