My pc has been restarting while gaming. It always restarts and the fans sound like a jet engine for a few seconds. I believed it was temp problems because of the fans, but I've got good temps while gaming and idle. I've checked my ram with memtest and passed. The only other suspect I can think of is my psu. I also had a error screen booting my pc from sleep mode. A window error screen told me my pc had to restart because it failed to boot (probably due to a hardware failure). Is my psu bad or could it be a bigger problem? Thank you for the help..
