In short. Starts -> shuts off -> starts up by itself. What could cause this? Pc is oc'd and without oc starts up nicely.
 
Might be. It doesnt disturb me, but im just looking if it can damage my computer ( i dont think so even if its something else)




 
Forgot to add that it is the bios like herrwizo said.
