Trine crashes

[osyka]

Trine crashes once every while when I'm playing. Each time it crashes I see an icon in the system tray that says "display driver atikmdag has stopped responding and has successfully recovered". There is no set amount of time I can play Trine before it crashes - it can be an hour or (mostly) 10-20 minutes. The crashes have appeared (or just gotten worse) at the wyrm-something caves.

My specs are:
AMD Athlon 64 7850 2.8 GHz
ATI Radeon HD 4670 1024 Mb
Vista Ultimate SP2

I'm using that latest drivers for both my video card and PhysX, I have disabled Catalyst A.I., running the game at 1280x1024 with AA and VSync turned OFF.

Thanks in advance.

This is the event data I've gathered from windows event viewer, listed under "system events".

Have you disabled ATI Catalyst AI? It might help.

I did, along with some other things I mentioned in the first post.

The GPU temperature during one of the crashes was 50C, so I think overheating is out of the question. However, I recently got two Blue Screens of Death in a row instead of a simple game crash... something about someone going in a loop.

Well... I can't guess anything else anymore than just that try updating your graphic card drivers.
