Black Screens (not the common ones)

[BlackDog]

Hi Frictional Games guys, I'm having an strange problem with Amnesia. When I bought it, I started playing it and everything seemed normal, but later on while I was playing, the screen went black for a few seconds over and over again. I mean, I'm playing, the screen goes black, then goes back to normal, and randomly goes black again, this happened all the time not letting me enjoy the Amnesia experience. At firts I tought something with my GPU was wrong, so I payed no mind because I was going to get a new one in few days. Well, today I've recieved my new GPU a NVIDIA GTX 660 OC, but the black screen stuff keeps happening, I have all the newest drivers for the GPU, downloaded this very day, so I dont know why this keeps happening DD:

I hope you can solve the problem so I can start playing Amnesia as soon as possible.

And BTW, I'm from Spain so excuse me if my English went wrong in any part of the post.
