Random freeze playing

Hello all,
I am having problems with the game. I recently installed it on my laptop (16gb ram, i7, 6gb nvidia gtx1060) and managed to play more or less 20 minutes or so, then the game randomly freezes. Audio can still be heard, however, I need to ALT F4 the game in order to shut it down.

As an add on, game is in Steam, installed in disk D: ; savefiles are on C:

What can I do to stop those freeze?

I had the same problem with the GOTY Enhanced version, but when I switched to the normal GOTY version it worked fine.

I know it’s not an actual solution, but it’s what I got.
