  Status      : 0xfa000010000b0c0f

This seems to be generic timeout error reported by the CPU, therefore the CPU has found a hardware error and reported this error with a Machine Check Exception, but wasn't able to identify which form of hardware of causing the problem.

I would check for any potential BIOS updates:

Code:

Award Software International, Inc. F5, 10/19/2012

Boot into your BIOS, and then post the values for the 3.3V, 5V and 12V.

Hopefully this is what you were looking for BlueRobot.

That 12V rail looks a little low in my opinion, I would download and double check with HWMonitor CPUID - System & hardware benchmark, monitoring, reporting

How do I use the HWMonitor CPUID? What am I looking for to be wrong?

And SpeedFan is supported for my MoBo.
