If you are so inclined, you could start Beyond Divinity again to re-install the Starforce drivers, and see if the random crashes return. If this is repeatable it sounds like there is some kind of conflict with the drivers; if not, it may have just been a coincidence.
I don't recall anyone else posting about random crashes in Windows after installing the game. It could possibly be an obscure conflict, or those that may have run into this attributed the crashes to a different program they were having trouble with, or didn't notice any significant increase in crashes.
