Hmm. Different GPU. Mine is running the GT555M but I thought nVidia ran packages across the whole product line.
I'm not really sure where to go from here.
My first thought is email [email protected] and attach the .dmp file, since from what I've found you/we won't be able to access what's in that file on our own.
The only other thing I can think of, is that the problem seems to be when the system hands off from the integrated graphics to the discrete graphics, it crashes. I've heard there's ways to disable nVidia Optimus so you run the GT560M the whole time. Hopefully there would be a way to re-enable it otherwise you'll be losing a lot of battery life.
I'm not sure what doing that entails, but if its not too hard, its an option.
I'll post if I have any other ideas.
Good Luck!
