I can see where this would be interpreted as a bug, since a lot of people seem to experience it. But it's probably more of a Technical Support issue.

Anyways, we could use some more specifics to help diagnose this... "Black Screen of Death" isn't very descriptive.

Is your computer restarting? Is it giving you an actual error screen? Is it shutting down completely? You posted event log information that makes it sound like your PC is just going into sleep mode.. but that shouldn't be happening while you're playing a game.

It might also help to post your system specifications.
