After testing my monitor and video cables, I've concluded that I have some sort of horrible problem with my computer, but I can't tell exactly what is responsible for the problem.
It started last night when I was just using Firefox. Static images started to flicker- single pixels would flicker between black and green. I started to notice that my wallpaper had little flashing pixels distributed through it... then, within 5 minutes, I had these horrible clusters of wrong-color pixels distributed in normal patterns across my screen.
See a picture of this here. Depending on what program is up, the pixels are a different color (example: in Firefox, all the artifact pixels are red, even though they should be a variety of different colors. On my desktop, they're green and blue). Also, some of the pixels flicker. When I move a window around, it smears the artifact pixels until it's a mess all over the screen. Redrawing (by minimizing the window) clears out all of the artifacts except for the original ones in the repeating pattern.
I tried turning off the computer for a few hours and re-seating the video card, but upon restarting I saw this related but different artifact pattern. In bootup, the artifacts are not single pixels, but entire character-sized blocks. They come in clusters of 4 characters across, and they're all static except for the second character from the left, which has all sorts of flickery red pixels inside it. See a movie of this here. Outside of these artifact clusters, at bootup, there are no other artifacts.
I tried running MemTest and ATITool artifact checker for a few hours, but neither reports anything wrong. ATITool said my card was running at less than 50 C at the time the artifacts first appeared, and I wasn't doing any overclocking (though I have... the most recent time was about a week ago). At the time the artifacts first appeared, my card was underclocked.
What is going on here? Did I get what I paid for with this video card? Can I fix it? Help!
My system:
ATI X800 GTO2 (flashed to open up all pipes, and it has been occasionally mildly OC'd)
Arctic Cooling ATI Silencer
EPoX EP-9NPA+ Ultra
2x1GB OCZ Platinum PC3200
Hyundai L90D+
Athlon X2 3800+
