Hi my friends computer is randomly unstable.

It appears whenever he plays battlefield 3 after a couple of minutes his computer will just restart.

No errors of BSOD!

Now ive done loads of prime test and randomly it restarts on it, sometimes it wont and sometimes after a couple of seconds.

the CPU temp is fine and the GPU is fine

Any suggestions?

Cheers

Are there any logs in the event viewer that mentions anything regarding the restart?

Also, restore any overclocks to default and run Prime95 and see if it still retstarts (I know it should give a BSOD, but no harm in ruling it out).

Try to run something else that's demanding electricity wise as just because the PSU is 700W doesn't mean it's failing and loosing its power output and/or voltage stability.

Check for BIOS updates
Try with the minimum hardware (1 Ram stick, no addons etc, if the CPU has onboard gfx don't use graphics card etc)

Try
http://www.nirsoft.net/utils/blue_screen_view.html
It should beable to show any blue screens you've had (If it restarts before you get the chance to see it) which may help.

give those a go before you go and buy a PSU
