New pc turns off on high spec games?

Hi guys, so here's my problem. I go to play Arma 2 or Crysis and after about 20 mins of playing, my computer will just switch off. The CPU's temp doesn't go above 50 and the Graphics card goes up to 65.

I only bought the pc a week ago so I don't see why this is happening? I thought maybe something to do with the power supply?

Here are the specs:

CPU: AMD Phenom 9850 quad core (Thermaltake blue orb fan)

GPU: Nvidia 8800gts

RAM: 4gb

PSU: Colors 600w gold 12cm silent atx power supply

The CPU and GPU are standard and not overclocked at all. Also the case seems well cooled.

Any help on my problem would be appreciated. Thanks

Also, thought I might add, I'm running windows 7 ultimate.

The OCP/OVP or OTP may be tripping in your power supply, and that could be a sign that it's about to kick the bucket. Do you have a spare PSU on-hand that you can use to test your components with?

All I have is a 400w PSU off my old computer. Don't think it would be good enough.

Is there anyway I can check if my PSU is failing from within windows?

Just checked my gpu temp using a different program and it's idle'ing at 85 degrees!!! I take it, this is my problem. Anyway I can lower the temp using drivers etc? Thanks

Use rivatuner to turn up the fan

I already have the fan on 100%

My bet is on the PSU not being able to supply good consistent power, Colors arn't really known for their high quality products.markop2003

Couldn't agree more. I would say get a better PSU, a good branded one such as Corsair ect.
