Most likely psu on the way out or board/cpu overheating. What's the rest of the system specifications?

Have a go at manually set the ram timmings and voltage in the bios, and if you have all 4 ram slots occupied up the northbridge voltage by 0.1v/0.2v to cope and see how you get on mate.

EDIT - also having all the ram slots used will affect your cpu overclock, pop the cpu back to stock settings and do as described above and see how you get on

No problem, if that still fails mate, download and burn to disk THIS and run it with each ram stick individually and see what it comes up with
