My computer automatically restarts all the time.
I then get an error message on restart: Power surge detected on previous powerup. Power surge protection activated to prevent damage from faulty PSU.
Have tried replacing cable. No large electronics kicking in or anything. Power draw on the PSU is well under Max spec. A while ago ASUS bios was showing 3.3v rail as red drawing ~2.9V.
MOBO: ASUS P8H61-M LX
