a couple of months since I'm using my new Video Card, I notice when I encode video files, I get blue and other colored small flakes in my rendered video avi or mpeg. I did not have this problem with my old video Card.

then I switched back to my old video card, now same problem I get, My old video Card never had that kind of problem before. even with the same video files i used that never had a problem before, but now dirty flakes are seen on my rendered video.

even I format and re-install my OS several times but no changes at all.

I was wondering anyobody could help.
