Hi, Hope someone can help me .... I have windows xp pro o/system and when I try to shut down windows, it goes through the normal shut down things, WINDOWS IS CLSING DOWN AND WINDOWS IS SAVING YOUR SETTINGS but I used to get a screen saying IT IS NOW SAFE TO TURN OFF YOUR COMPUTER but this does not appear. The screen goes black but then it starts up again ! Unless I turn off the power this happens everytime. Please, please can someone help me ?
