I have I strange problem, after Vista come back from sleep. It freezes 10 seconds, 60 seconds are ok, then frezees again 10 seconds, 60 sec are ok, in regular intervals.... I that 10 seconds, I can't move mouse (pointer ) and desktop is frozen. The strange part is that sometimes it doesn't freezes after sleep. The problem was before and after SP1 instalation. I pull out my creative sound x-fi card and it didn't helped. I denistaled most of system hungry programs (google desktop, mysql, soundcard drivers...) Reinstalled graphic drivers... Nothing helped I need sleep option, it saves mi a lot of time... my conf: MB: P35-DS3R CPU: Q6600 Graphic: XTX 8800GT
