Screen flashing since new patch, unplayable.

Since the Nightmares Within patch I’ve been unable to play the game. The first time, I could play for a bit, but then my monitor goes black and shut itself off. It didn’t seem to overheat or anything, but I figured it might be dying, so I bought a new monitor. Trying to start up it today after the mini-update, the screen now just flashes black and white. In both instances I’m forced to hard reset my computer.

The game ran fine before, so I’m just confused. I run an AMD Radeon HD 6670, if that makes any difference. Drivers are up to date.
