How often do you see this bsod?
I've seen it happen thrice in the last two days. Before this it was just random rebooting.
Does it always happen when you're performing a particular task?
Not that I know of. I've just noticed that Sygate and Firefox have begun crashing more frequently (too many times for me to keep count).
It's probably a driver problem or may be even your anti-virus, have you installed any new hardware recently or anti-virus software? Is this a new Windows install?
It's an old Windows install but I had another RAM module installed about a month ago (that's when all the troubles began actually).

This is what the event logs of the random reboots look like:
