Windows 7 Unexpected Shutdown from Desktop BSOD

My computer keeps shutting down and giving me the following error:

I am not gaming, watching a movie or anything particularly strenuous. It will shut down from desktop, it will shut down when I'm on facebook or Tumblr in Google Chrome. I am not sure what is causing the problem. Attached is the SF Diagnostics zip file as per the BSOD instructions page.

Any help would be much appreciated.

A "stop 0x124" is fundamentally different to many other types of bluescreens because it stems from a hardware complaint. Stop 0x124 minidumps contain very little practical information, and it is therefore necessary to approach the problem as a case of hardware in an unknown state of distress.
