It's surely a 'normal' DX crash. Press Control Alt Supr next time it freezes and look in the Windows taskbar if it shows something about that.
Been having the same problem also. Three times today alone. My keyboard and mouse are also frozen. Game has become unplayable. Should I go in and delete all saved games and just start over or delete the game entirely and reinstall it?
@Marcus_Killsalot A dxdiag is a good place to start from. In the meantime, are you using any mods? If so, try getting rid of them, see if that helps. Try repairing your game (right click on it in Origin and select 'repair game'), far less downloading required than a full reinstall.
