Hey, this problem started yesterday, randomly last night my Computer just locked up, out of nowhere, couldn't click anything, mouse icon was gone, keyboard unresponsive when I pushed caps lock the LED didn't change and ctrl+alt+del did nothing either, had to hold down my power button and restart that way, when I did restart however everything was fine again.

Then today, I'm on my computer for 4-5 hours, I get this random lock up again, so I restart everythings fine...then an hour later, I get it again.

I haven't installed any new software recently, I did install the new windows update AFTER the lockups today though.

I built my computer myself 1 year ago the specs are as such

CPU: i7-930
RAM: 6GB DDR3 1600MHZ Tri-Chan Corsair XMS3
PSU: 650W Corsair HX
Mobo: P6X58D-E
GFX: Radeon HD 5770 XFX 1GB

I'm not hearing any weird sounds when the system locks up (no beeping or anything to indicate any hardware issues) and it's 100% not a heating problem as on stress test my CPU/GFX doesn't go over 50/52 @ 100% for around 2 hours.

Any idea what this problem could be? help appreciated greatly.
