Sounds like the power supply to me, remyhome asks why his computer keeps turning itself off. Overclocking is fun but hifideliti is having a problem with his X2 4400+. Lastly check out johneva916's new watercooling system. =D

Right after some advise from others I have desided against getting an external water cooling system and instead building a custom water cooling system and mounting the rad externally on the case.
