Is my PSU running too high on the 12V rail?

My rig is about 4 months old now and just the other day it started randomly restarting whenever I play CS:GO. It does a hard restart bringing me to the "Windows did not properly shut down" screen and sometimes it has to try 2-4 times to restart (like starting a pull cord on a lawnmower) before it finally "catches". Current system specs are:

AMD Phenom II x4 965
MSI 970A-G43 mobo
MSI Radeon 7770HD 1GB
8 GB G.SKILL Ares DDR3-1333
Corsair CX500 500w PSU

I Haven't overclocked anything and my temps seem normal. GPU stays under 60c when gaming, processor stays under 55c. I've run windows memory diagnostic and it came back normal, maybe I should run memtest but then I looked at CPUID's PC Wizard and my PSU readings seem waaaay out of range. 3.3v rail looks ok @ 3.25V but my 5V is reading @ 3.07V and my 12V is reading @ 13.86-13.99V. Haven't tested it with a multimeter yet but might have to.

Any suggestions much appreciated.

It could well be a PSU issue. Although Corsair is a good PSU, the CX series isn't that great. If you can test it, then by all means do so.

I don't think it's the PSU.Maybe a bad ram module.

I have the exact same issue, with a different PSU but the same motherboard. I have a Lepa n500 500w PSU, and my +12v rail shows 13.3 min and 13.8 max, while +5v is 2.93 min and 2.95 max. Measured my reading with CPUID Hardwaremonitor. Other voltage readings are normal. Is this something to be alarmed about? I have 2x4gb Crucial Ballistix Sport ddr3-1600 memory installed and a AMD FX-6300.
