My pc freezes sometimes while playing games, sometimes just watching youtube videos. I have to restart my pc but then i get no power to mouse/keyboard and no signal to monitors until i hold down the power button for a minute. It's only recently started happening about the time i got fallout 4 but now happens quite frequently even when not playing games.
My motherboards pentium i7, 8Gb of ram, 4x2Gb ddr3 cards and nvidia Geforce gtx 970 graphics card, running windows 7
