PC shuts down in the middle of gaming, I can't figure this out

I recently built a computer with the following specs:
Asus Rampage III Gene motherboard
Intel Core i7-930 processor
Radeon 5870
6 GB ram
650 watt power supply
80 GB Intel X25-M Solid State Drive

It starts up fine, runs perfectly, EXCEPT and ONLY when I play a game for some period of time. I can leave the computer on, or just browse the web for the whole day and it works fine. It's crashed from Modern Warfare 2, Starcraft 2, and Crysis: Warhead. After awhile of gaming, the computer will spontaneously initiate a normal windows shut down (all programs close, logs me off, then shuts down). All examples of PCs shutting down during gaming I've googled have the computer powering down as if someone pulled the cord. This does *not* happen in my case, the computer initiates a regular windows shut down in the middle of my game. I will typically get some warning signals that this is about to happen by some video stuttering and some strange audio sounds (through the speakers, not from the computer itself). I have ruled out:

Video card issue - This problem happens with multiple video cards

CPU issue - I was almost certain it was a CPU overheating problem, until I sent my i7 back to Newegg to be replaced. Got my new one today, same exact problem after about 30 minutes of starcraft. Temperature monitors are also reporting within a normal range.

This is frustrating me to no end. I've researched this extensively, and I can't find a single other case like mine. No blue screen, no error message, and a *normal* windows shutdown in the middle of gaming. Also, the computer can power back on immediately afterwards. I tried my best to research and solve this on my own, but I really have no idea what to do at this point. I would greatly greatly appreciate some more knowledgeable people weighing in here.

First thing I'd do.

Try running furmark, if that crashes, try running prime95

If they both crash, I'm guessing its your PSU.

2nd thing
Bad ram, run memtest86 - much more likely than a bad CPU

3rd thing
Check your video card drives, uninstall, reboot, run driver cleaner, reboot, install new drivers

Keyboard problems? Possibly hitting a shutdown key sequence accidentally during the middle of a game, perhaps due to ghosting?
