Randomly, Windows 7 switches to Basic theme, and the GPU sounds like it's going into a self-test. Progressively ranging higher and higher pitched squealing sounds. I've had it happen with different cards in different computers.... WHAT CAUSES IT??? (EVGA cards)

When this happens, go into your Task Manager and check for a Process called WinSAT.exe. If you see it, then the reason this is happening is because of the Windows Experience Index test that Windows likes to run periodically and will keep trying to do if it hasn't been completed in a while, or if new hardware has recently been added like a new GPU.
