Ok lately anytime I load any 3d intensive software my pc reboots with no error. Nothing in event viewer, I have the auto. restart unchecked but nothing. I just installed asus probe and the first thing that beeps is the +12v and thats reading 13.504v and also the +3.3v is showing 2.896v. My cpu temp is 50c and mobo is 28c. The power supply is only about 6-7 monthes old. It is a 420watt which was upgraded from a 250 watter. Is my psu a piece of $hit or what?
