I am having the same exact problem. I've tried everything: from unistalling, reinstalling, removale of the card, etc. Today, I reinsatll WINDOWS, crazy I know. I still have this annoying problem. INTEL, please help us.
well, now i am not so much experiencing the problem as I sort of tuned up my computer with iolo tune up technologies. You can try using that. It detected and repaired some hard drive errors. Maybe it had something got to do with it.
