When loading a new map, game freezes at the end of loading and won't start, So i Ctrl+Alt+Del To exit,, WHy is that ??

Depends on what kind of map are you loading ? Also can you start the game minimized and then tell me what the error says ?

turn off xfire

UP. Same problem with random maps, sometimes it loads them, sometimes the loading bar finishes and then the game freezes. xfire disabled.

Do you guys have the DLCs installed?

Yes, have all 4 DLC installed

run in windowed mode and if the game freeze switch to the console and upload a pic.

You might be missing some DLC fastfiles.

Solved easily. My computer had been running straight for about a month. So one night i decided to shut it down. Next day everything was working fine.
