My X1950Pro is about a year and a half old now and I think it is dieing. I can't run AoC, my card stops outputting video for about 5-10 seconds every minute, and does this weird thing in games were it seems like it forgets a point on a texture and a triangle stretches on forever. Here are some examples in wow, but it happens in AoC, Overlord, SupCom, and EVE. Also, I get flashes of odd textures on my screen, not big, like a single frame of distortion on on part of the screen.
Also on black backgrounds I get what looks like green frozen pixels, that go away when the black does, but things like minimizing don't work. I have reinstalled DirectX, drivers, windows, and nothing works. The Green Pixels also occur is BIOS start up so it is hardware.
I had the same problem with my old 9600 Pro. Polygons would stretch right across the screen in games, then eventually the card started artifacting even with an idle windows desktop. For me it was the card that was dieing, a new X1800 AIW put everything back to normal.
