Constant Crashing

Ever since I got to maps for some reason the game crashes every few minutes. Started new character and Town Act 1 crashes every 1 or 2 minutes for me. Then when I'm slaying monsters it crashes every 4 or 5 minutes.

My first play through back in early December crashed once or twice. Now it's every few minutes. Very confusing, there doesn't seem to be a culprit. Tried this with different characters and crashing persists.
