I just finished building this computer today. All the parts are compatible, There is no problem with overheating as the CPU and Graphics card stay with 30-40 Celsius.

The system runs completely fine and without problems, up until I go and try to play a game. In this case WoW; Prior to this last shut down I lasted about 15 minutes playing before it shut off on me. This last time I lasted about an hour and a half.

Edit: When starting the computer back up after the shut down, The computer is Extremely slow once logged in. It is as if the computer had 250mb of RAM and then shortly after it freezes

I have performed a Memtest without any errors, As I Originally thought that as the problem. I have also performed a Burn In Test in hopes of finding any errors that way. But unfortunately nothing came up.
I have no clue as what the problem could be, Here is my system build.

Trying that second stick had the same result of an abrupt shut down. Trying a 3rd one, But now I feel as though the Ram is not the problem. It took 12 minutes for it to shut down from the point of starting up and going straight into playing the game.

Crashed again on the 3rd stick, I takes the same ammount of time to shut down each time. I seemed to be a moron and missed the CD that had all the drivers and GPU tweak on it for the motherboard...So i'm gonna go ahead and insert that

I don't have another power supply to test with. After installing the drivers and making sure everything was up to date, It still crashed. It seems to vary on how it crashes. Most of the time it will just shut down and then try to restart its self. Other times, such as this one, It will freeze and make a high pitched sound through the speakers.
