I was over at my friends house and after a couple hours, games would crash and the screen would discolor green and pink. This happened several times, and once when it booted up, the resolution dropped to 800x600. I fixed the resolution, but there are still discolored pixels. I tried changing the refresh rate thinking it was monitor flicker, but it wouldn't let me; it just said hardware default. I also unplugged the dvi from his viewsonic monitor and plugged it into his sony tv, but the pixels were still there. Then thinking it was artifacts, I set the clock speeds to their factory default on his MSI Afterburner GTX 680 (reference design). Here is a link to a photo of his desktop:
