Hey guys, having a little issue with my PC. If I'm in a game for a while (or graphic intensive program like furmark) the monitor will go black (get put in sleep mode), the sound from everyting not including the aplication i was in will continue for about 5 seconds and stop. Then the PC locks up and I have to manually start it. Chkdsk and memory test both are fine so I'm guessing its either my PSU or my GPU, would anyone be able to narrow it down or anything? Kinda desperate to get it fixed before I head to the LAN at 3am. I also wondering if anyone is bringing spare parts thatI might be able to borrow over the LAN if I don't get it fixed.
