Graphical Freeze

[FXStrato]

So I've come across this error. FF will freeze, and appear like this: http://i.imgur.com/h4sMvDr.jpg
EDIT: Ran it again to see if I could replicate it, ended up with this: http://i.imgur.com/z1iWLmr.png

I'm assuming this is something to do with my computer, and not FF, but I'm completely in the dark for what is causing this problem.

I have the latest version of the Nvidia drivers installed, done Prime95 tests and passed them, passed the FurMark benchmark test, and the temps for CPU and GPU don't even go above 65, so no overheating problem. Also performed Memtest twice to see if RAM was the issue, and it passed both times. It's just whenever I start the game and try playing it for a bit, then this occurs.

My specs atm:


CPU: Core i7-4770K
GPU: Nvidia GTX 660

I run a 750W power supply, more than enough to cover for it.
