I built my PC about a month back. It has crashed 4 times while gaming so far. The first 3 times it would just restart automatically. I thought that maybe the temps were too high, so I started monitoring the temps. Before my pc crashed for the 4rt time, my cpu temp was 50 c and gpu 60 - 70 c. This time when it crashed it didn't turn back on. The motherboard led is on, so is the cabinet led and power led but cabinet fans, cpu, gpu, nothing is working. I have a fan connected to the psu directly which is working.
