Hey, I hope someone can help, I have a strange intermittent problem with my video card.
It is water cooled and overclocked to 790MHz core.
Neary every video I play on youtube (or any other website using that sort of embedded player) causes my screen to flash - displaying around 100 white vertical lines, and then about 1 in every 10 videos does this and also crashes my computer. It then either undergoes a forced restart or remains on with a black output.
The other 9/10 times, my youtube video loads and plays after this with no problems.
It has never happened during gaming or running folding@home, only if I play a video.
It happens in XP x32, Vista x64 and Windows 7 x64.
It still happens if I downclock my card to 750MHz.
I have all the latest drivers. This fault only started to happen after a XP driver update around 3 months ago, but I haven't moved back to older drivers as the fault also began to occur when running my Vista partition.
I guess what I'm really asking is WTH? Does anybody have any idea what is going on? Could it be that the embedded video may be forcing my gpu clock speeds to change? If so is there a way to override or prevent this?
[Update] it has now begun doing the same thing when I play .avi videos on WMP in Windows 7. It hasn't done that before with .avi files when I was using VLC, but I just upgraded to 7. {Will double check WMP in XP and VLC in Windows 7 and let you know}.
