This morning I tried turning on my computer at work, and it got to the login screen (win xp pro) and I entered password and hit 'enter'. Icons started appearing and screen froze after three-five seconds. I've tried starting in safe mode as well, and the same thing happened. I am forced to restart after each freeze. It happens regardless if I login or not..meaning I can get to the login screen, and if I wait a few seconds it freezes there. Can anyone help me out? Thanks.
