We have nearly Identical lap top specs and the problem. As Enth points out it only happens to me when looking up locations as well. However I have never had a crash. I alt ctrl del and windows manager pops up I click abort and I am able to get back into the game, often at the progression point I desired. I dont get it every session though, which is odd. I did do a reinstall, still occurs but appears pretty randomly for me.
Exact same problem here .
