My pc will always freeze when playing a game and my peripherals lose power. This doesn't matter on what the title is, even games like dirt 3 and csgo. My gpu and cpu are running at stable temps and it will freeze when i stress the cpu using prime95. I have just run memtest and the ram seems to be fine as it passed no problems. I'm running a gtx 1070, an i5 6600k at 3.5 GHz with 16 Gb of 3000MHz Ram on an ASRock z170 extreme 4 and a corsair rm650x psu. Any help would be amazing.
