Was playing Battlefield 3 campaign on my new, recently built PC. Haven't crashed before this but I also haven't got to play it much till now (maybe 30 min-1hr a few days before this).
I actually did not receive a BSOD, it just crashed and restarted. The error after reboot told me it was a BSOD, though.
Edit: Just locked up again. Didn't restart but it froze and I had to manually turn it off. Running like 130 fps with temps in the 63 degree range during a pretty low key time in game, graphics wise.
