The first two weeks I had the laptop, it didn't happen, then it started on Friday. The lock-ups are random and happen when the game is the only application running and when others are running as well. CPU and GPU utilization are well below max and temperatures are fine.

It happens when I first launch into the game and try to log in and when I'm in the middle of just running around the world and there is no pattern. Sometimes it's immediate, sometimes it's after hours of play.

I've tried the latest video drivers, I've tried FurMark GPU test (passed), memory test (passed), I've tried uninstalling and re-installing the game, I've tried booting in clean mode and running it and, finally, two days ago I restored the system to before the first lock-up and it locked up again this morning.

I'll add the system information to this thread here shortly.
