As the title says, the game just likes to shut down completely with no warning, no error messages, no anything, at random points. It only seems to happen outside, and more often when there's a lot of combat going on. In particular the battle outside of Whiterun, I couldn't get the game to work for more than five minutes or so at a time. I'm unsure what's causing it because there's no error messages, and it can happen even when just walking, or even standing around outside. Just a minute ago it crashed when I exited my tab screen, before that it had crashed when I tried to pick a flower, and before that it had crashed when I tried to move toward the rock just outside of where you come out from Helgen. My friend's having this same problem, and we really have no idea what's causing it. All I know is that it pretty much only happens outside.
