guys please help me I have a I-7 8000k, geo force gtx 970 , 500w psu, ssd 1tb; prior to this I had same specs except I had a 450wpsu and pc was OC with only 512gb ssd. I was having black screen during my gameplay on call of duty mw3. The game would go black during gameplay but pc would stay on until I reset it rinse repeat; my friend took the PC cleaned it installed more ssd installed new psu cleaned up messy wires and told me not to overclock it he said it blew the last psu or fuse not sure. However, I got the pc back installed Mw3 along with a few minor apps everything seem to work good until a few hours in the computer turns completely off and reboots; unlike before it just black screened until I reset pc. Please help as I
