Hello. My pc keeps restarting after I login, or a few minutes when I log in, and sometimes a few hours after I'm logged in. It restarts after login most the time and then keeps restarting. The first time I experienced this was in June 2013 on Windows vista but it would only reboot before the windows logo. Problem has gotten worse and it restarts all the time now ive even installed Windows 7 on the pc getting rid of vista. This hasn't helped at all. My pc doesn't restart in safe mode, I can leave it on for hours on the log in menu and it won't restart, also im currently doing a disc check and been here for 2 hours now and it hasnt restarted. It only restarts when logged in. Yes I have unchecked automatically restart in the control panel. Please any ideas or help?
