Computer restarting randomly while gaming

  1. Hello!

    Well, the title says it all. It restarts whenever I play games (for example AC4, BF4, etc). It is completely random. Could be an hour, could be less. Once it was like 5 hours. It is not overheating, as it doesn't go higher than 60°C (both cpu and gpu), and it's not the gpu since that was my first suspicion after the fans just keep spining and the pc wouldn't recognize it, so I RMA'd it. They sent me a new one, and it worked fine until it crashed again. I suspect it could be the PSU, but I want a second opinion. Oh, and I first sent it to the store all the pieces in, and they said everything was fine and they sent it back even when the GPU was not being recognized.

    Here are my specs:

    Intel Core i7 - 3770 @ 3.4 GHz
    Motherboard: Gigabyte Z77 D3H
    Cooler: Cooler Master Hyper 212 Plus
    RAM: Kingston DDR3 1333MHz (2 sticks) 8GB
    GPU: ASUS GTX 670 2GB
    PSU: Thermaltake Smart M850w
    Hard drive: Seagate Barracuda 1 TB
    Case: Cooler Maste HAF 912

    And here's the error in the event log:

    I have the same motherboard. Get into the bios and under Advanced Frequency Settings, Advanced CPU Core Features... Disable C3/C6 state support and the CPU thermal monitor. The bios version is up to F21

    CPU thermal monitor? What for? I mean, doesn't that mean that it can overheat without me noticing? D:

    Please explain, I'm kind of new to this stuff.

    Disabling the CPU thermal monitor keeps the CPU from slowing down during game play... C3/C6 stepping also slows the CPU. You don't want this to happen during game play

    How will that help with my computer restarting randomly?
