You have nothing to loose.
Very true and I do know how to save profiles and maps. In fact I always move my profile to whichever PC I will be using.
Everything is updated, in fact did the video card twice just to be sure.
Shamu mate its not your game.........If you can search my posts from a couple of months ago I went through exactly the same problem... ITS EITHER YOUR GPU OR CPU OVER HEATING......
The more detailed the map the harder your GPU has to work creating more heat.....Msi afterburner will give you a better idea of temps...What I did was try to work out how long into game did the comp crash then start playing and just before the comp crashes get out of game and check your temps ....
