So I was just watching some Youtubes video when my PC suddenly shut off then immediately reboot. It took 20-30 minutes to boot back to windows . Opened up HWMonitor and noticed that +5V and +12V was way too low (4.32V and 10.176V respectively). Tried to restart but it took just as long to boot. Dying PSU? Build this PC a year ago and the Psu is a MasterWatt Lite 230v 600w
