Hey, i decided not to repair it yet. I run the system into safe mode, and you know what, all the problems disapear. I think this must be caused by the system's driver, only i dont know which one is causing it . I tried to diasble the graphic driver but it does not work. Ill try this on the other drivers. ill report the outcome.
Btw zidane, is the latest windows 7 build that u tried is the rtm?No issues so far?
