The game was running fine for the entirety, despite Nvidia's assurances that my PC couldn't handle the "optimal" settings until I reached Diamond City. Now, the game crashes every time Danny Sullivan finishes saying, "The whole city is in a tizzy." There is no error message, no warning, the program just shuts itself off. Any ideas? I've tried all the advice from the Bethesda support page, and nothing works.

It would be nice to post a Dxdiag!
