your gpu stopped working... i would assume Ram or a hardware issue like ports

is the 1TB drive external perhaps?
have you tried lowering the graphics i.e, med instead of high and refight the battle?

also load up another game [benchmark] to test your Gpu is otherwise working... Windows updates just love highjacking Gpu drivers after a crash [they caused]

Luke Skywalker: I don't, I don't believe it.
Yoda: That is why you failed.
