PC boots up totally & then proceeds to shut itself down immediately after successful boot up. The shutdown is 'normal', just as it would be if I logged off & did the shutdown myself. No 'blue screens' or error messages displayed, just 'Windows is Shutting Down'. What can the issue be? Started pc in 'Safe Mode' & pc remained on...no auto shutdown. Any ideas and/or help would be greatly appreciated! Thanx!
