While playing HoMM 5, my computer will restart unexpectedly.

I can't seem to determine when it will happen while I'm playing but there is one point where I can cause it to restart consistently: In the "Queen" campaign, on mission 4, "The Trap", there is a small underground section near your home base which contains a Ruined Tower. When I try to interact with that tower, the computer restarts.

I have not had this issue with any other games that I play.

Any help on this would be greatly appreciated!
