I bought this game yesterday, and during gameplay I've twice had my computer die unexpectedly. This wasn't due to a lack of battery (as it was full when I turned it on again), and hasn't happened to me before on this PC, which I've had for a number of years. It doesn't display a shutting down message, or anything, just switches off and tells me that it 'shut down unexpectedly' on startup of my computer.

The two occasions when it's happened so far were both in the starting town, in dialogues. The first was while Isabella was asking to join the expedition, the second when I was being asked for help to find a missing wife (IIRC, I didn't have enough time to really take in the quest). In both cases, I was in dialogue, deciding what my response would be.

I remember a similar effect occuring on a vista PC I had a while ago when I tried to run things full screen, but I believe that was fixed by a service pack.
