Same problem here. The game often crashes in Wilhelm's cellar when the wraiths scream during their attack (maybe the sound file is too big?).
I managed to pull through after a few crashes and one reboot, but had to throw the towel on the way out when the game crashed again. I used the console to teleport myself back to the village, from where I just entered to top part of the dungeon to finish the quest.
