Game goes to black screen then restores with frame lag

[ThatFishySmell]

As the title says, randomly the game will go to a black screen with only the mouse pointer showing. When the black screen returns my entire computer slows down until I exit out of the game. Here are my specs just in-case:

GTX 660
AMD FX-8350
12gb ram

Also running dual-monitors in the case that it may be relevant. I've used drivers 314.22, 320.49, and 326.41 and none of them fix this problem.
