Any other way to launch the game than through steam?

Also if you are getting BSOD from launching Steam, your computer has serious issues (possibly hardware problems like bad RAM).

Oh, didn't see that.
I recommend immediate backup of all your data and then I would proceed to reset any overclock to standard do a clean install of Windows, to see whether it is software or hardware based.

If the issue persists, more drastic measures may be applicable.
