[hatred]

Here is my configuration:
ASRock P45R2000 / Q9300 2.5Ghz / 2x1GB RAM DDR2 800 / 2 x 160GB RAID 0 / GeForce 9800GT / power supply 550W.When i start my pc to play games the
PC games are totally cut after 5 to 10 minutes.


The air temperatures were OK, trial and graphics card are ... cold, the radiator chipset is against a little hot but good .is that this may explain the arrest? Another explanation? What can I do? Mounting a fan above?
please help me

I thank you in advance

Hello, if this pc cut during the games ......

should be a test of stability, will see a couple of OCCT(OverClock Checking Tool), if the test plant there is a problem, it may come from the trial or the ram, the food (Corsair) I believe this is ok .Oveclocker PC? should be a test of stability, going to see a couple of OCCT.

Your radiators are "cold" ?!?!?!

Normally a game melted the radiator of your graphics card which should become more .

If it is cold, it makes no contact with the processor ..Everything is well cushioned.
