Computer Shutting off During Gaming

[Rangesunit]

In November 2007 I bought a custom PC. The company i bought from are basically pathetic. So no mentioning asking them. I have just bought a new Case for my computer. 22Cm + 12cm (X2) Fans. Im 100% sure this is NOT overheating. Whenever i go to play games. Like Crysis, COD4, TF2, BF2. After around 10-30 mins ingame. My computer compleatly shuts down.

The graphics card is fine. I have tested this on other computers. Motherboards fine. The only thing i havnt checked is my Powersupply. Its currently 400wt. Should i upgrade this concidering my rig is pretty powerful. And what should i upgrade to, And how much should i pay for a good powersupply (GB£).


Many thanks

Scott

Check out your power supply requirements with the link above.
Without more info on the spec of your pc we can not give any more advice. I can recomend Corsaire psu's.

You may need a better cpu cooler, or it may just need reseating along with new thermal compound. Try checking your temperatures with something like SPEEDFAN or Everest Home.
