Hello
I've played GC2 last year without any problem, put it aside some months ago, and just now rediscover DA. Yet I have many PC freezes with the game, I didni't have any before !
What happens is that if I lauch the game, load a save, and just leave the room 10 min or so, I find my screen all corrupted/garbled (with lines of random dots..) and the PC is frozen, hard reboot necessary.
And when I play I have the same thing but it's rather random and happens after 1 hour, or 4 hours of play, or not at all !
I suspect it's a driver issue, but I got the latest drivers for my GF6600 (93.71) - at least they're the last according to Nvidia.

Here comes along my latest debug.err file - I just loaded the game, left the room and found it crashed 10 min after when I returned ...
Do you also need the Dxdiag file ? (sadly this board doesn't allow to upload files...)
