I had an installation that used to crash me all the time, in random places out in the wild while just running around. I deleted the game and the left over folder and everything except my saved games, reinstalled the game and then all the mods and poof, no more crashes. I think it might have had something to do in the fact I would try a mod out, not like, uninstall it and then try another one, over and over and over again. Just my 2 cents.
