|LCD or CRT monitor? A faulty control board in an LCD monitor can cause the panel to randomly black/white out. If you're using an LCD, test the computer with a different monitor. If it's a CRT monitor, you can count on the problem being with the computer or video card.|
Does it go out only when you stress the video card, or is it completely random?
