Random crashes

[Theditchmonk]

I built a new computer and am having issues with the computer randomly restarting when I try to start up programs. So far it happens with WOW, when I was loading the star wars beta test client, and even running older games like star battlefront.

My build is
Asus p8z68 v pro gen 3 mobo
I5 2500k processor
16 gig (4x4gig) corsair vengeance low profile
Cooler master silent pro gold 800w psu
Radeon sapphire 6870 1gig
Crucial m4 128 ssd (boots in)
WD caviar blue 500gig data hd
Cooler master haf 932 case

I've tried updating drivers, running through on board video (disconnected VGA power and plugged monitor in to mobo video out), taking out half the memory sticks and then swapping. Checked memory settings and running 9 9 9 24 @ 1600 MHz with 1.5v power. Anyone got anything else to try?

Have you tried cleaning the resource wasting garbage and registry errors with CCleaner? Do the Clean and Registry both. Defrag. Reboot.
