Fatal hardware error causing your OS to run unstable.
It'd be nice if I could receive the minidump from the bsod (in 'C:\Windows\Minidump') as it can contain more information about the crash.
I'm also going to bed right now, so you might need to wait for a while to get it read (unless someone else does it).
