Win 8 Shutting down in booting itself.
I have cleaned install windows 8 pro by formating. Previously i was using windows 7.
Pc was running smooth 2 days. But now i have this weired problem that PC switching off itself with out showing the login screeen.
All i see is windows booting then PC switching off. But it look like a shut down i don't see like crash. It happens just after the windows loading screen. (Blue windows and below small circle rotate as dots)
But there is a way that i can avoid it that is to press some key in key board.. Then it goes to logon screen with out any problem. If i don't press a key it just switching off itsef and it is pretty annoying. Once i go inside (By pressing any key in keyboard) i don't find any warning or errors in event viewer. There is no sign of system crash. I checked power plans. nothing wrong here. It just running Balanced profile. Only change i have done is Disable the hybrid sleep because i have a UPS.
There is no heating issue here. Becase if i press a key and hold in keyboard it just goes and work with out any problem as long as i want. But with out a key press while or after loading it is geting off itself.
