If it's actually shutting off then I would say power or heat. What power supply do you have and what are your temps while gaming?

+1 ^^. Those temps, if correct, for the MCH and IOH are awfully warm especially at idle.

Is the North bridge chipset fan running? Or does it have a fan?
Download CPU-Z you can get it here and run it, and you will see a voltage reading on your cpu core volts, and just watch it a while and see if the voltage goes up and down a lot then it might be your power supply....you can also monitor the volts by rebooting and going into the setup program and watching the "PC Health Status" for extreme spikes in voltage.
Do you have the four or six pin 12 volt connector plugged in to the board?
That's all I have for now.
