Each time it happens ( I mean it happens frequently :-[), the screen only shows a blank screen with a busy cursor. Then i have to reboot my pc and find another way to access the desktop (omitted).Finally i found the closest item to the power error in system events viewer is cmdguard(6.1, time-ish thing) succeeded in loading and registering to filtermanager ( translated in my own words). So this problem relates to cfw, doesn’t it?
