Hey guys I have a problem with my custom built computer it is i7 4770k gtx 780 8gb ddr3 750w bronze corsair PSU 1tb HDD, 128 GB ssd. The problem is that Today I just downloaded metro last light and I was about to play it but after under 2 minutes the computer just turned off by itself and wont turn on again. The PC is only 3 months old there isn't too much dust in it why is this problem occurring? I tried unplugging and replugging the bios battery because someone told me that might help but it still isn't turning on.
