You have a very new CPU, I would look for a BIOS update even though your BIOS is pretty current.
I would also install the intel chipset updates directly from intel

bugs and fixes to CPUs are done in microcode changes in the BIOS or by a driver that is installed during boot (mcupdate_GenuineIntel.dll) for intel CPUs your update is from 2010.
that is the only driver type of issues that I see that could cause this problem. All the other causes would be hardware, (fan, thermal problems, voltage settings to cpu incorrect)
The CPU was not overclocked when the bugcheck occured and I did not see overclocking software so do the BIOS and chipset update and retest to see if it fails.
