It happened once today. Restarted the PC, everything was fine. Came the login screen, typed my password, and it was good. Windows is loading your ... and it hangs. No movement no nothing. Restarted again by pressing the restart button as no respond even from the keyboard or mouse. Went in and this time everything was ok. Checked my event log, found nothing special at all. Any idea why?? I believe its the sign ..
