If you're running the Battlefield: Bad Company 2 beta through Steam and have a DirectX 11 capable machine, you may be experiencing more crashes than usual with the game. As it stands, the current non-beta Steam client does not play nice with DirectX 11. There is a simple fix for this and it merely involves opting in to the current Steam client beta.
All issues with this particular beta should be posted in this Steampowered forum thread.
Battlefield Bad Company 2 is one of the first few D3D11 games on Steam and we've become aware of an issue with it's use of D3D11 and the current public Steam client/overlay that is causing crashes for some of you.
Fortunately, we currently have a version of the Steam in-game overlay in testing that fully supports D3D11. If you are trying to run the beta and having issues on a D3D11 machine (ie, Win7 + ATI 5000 series) then please try opting into the current Steam Client Beta from the Account settings dialog in Steam.
