I know I've posted this several times, but I have somewhat of an update. My 8600 has been "glitching" ever since I bought it back in March. It usually only does this when I'm playing games or doing something else graphically intensive. It will freeze and the whole screen will glitch out and become pixelated. Recently, it did this partially just when I was doing nothing.
desktop again (the whole screen is usually like this and freezes)
I have concluded that my graphics card is faulty; I tried to return it both to the store I bought it from and the manufacturer with no luck. I would like to know if anyone has any more diagnosis/ways to fix this. Thanks a lot.
