I have an HP running with the 8800GT video card - recently I've been experiencing an issue with my CPU freezing up and showing a screen full of small horizontal red lines over the background. I'm not sure if this is a sign the video card is corrupt, or a bigger issue. I can't seem to find a solution. I've tried reloading the drivers, cleaning, etc. It will work for a little while but then it just freezes up again. Even in safe mode I will see red lines, but I can still navigate around the computer.
