Blue screen of death every since BF4 has been released

I just got the same issue on Windows 7.  I had been having hard locks with a black screen, and occaisionally needing to start task manager because the screen was frozen and nothing else (alt Tab, etc.) was working, but this was the first time since release that I got a blue screen error.  Nothing else on my machine causes this, so I have to blame it on BF4.
