Random shutdowns with no errors are symptomatic of a power supply issue. Does it only happen under stress? Do you have any OC affecting the motherboard? Are you hard wired or w a wireless adapter? What game(s) cause this to happen and when? During intensive scenes? At the same spot in a certain map? Playing online matches? Etc.

We need more background
