Just curious, how many people have experience the above? THe situation is I Have a 6800 OC oc'ed to 400/800. When I play games or benchmark, there are no artifacts that I can see, however when I play movies on WMP (and that's ONLY movies), I get weird red and blue dots once in a while. Is that the memory overclock choking up here? Or is there something else? Either a software or driver bug?
