Here's the story;
I bought a new graphics card, along with other parts, about a week ago. I put them in, install new drivers everything's working fine.
Now after a restart I boot into some lovely 1024x768 resolution with only one screen on.
I check in the NVidia X Server settings to see if my screen was changed there, there's nothing there except Application profiles and nvidia-settings.
I check hardinfo to see if the card is actually recognised;

VGA compatible controller:
NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1) (prog-if 00 [VGA controller])  

I don't really know much about the graphics end of things so I'm not sure what I should be doing here to fix this, I don't even know what I should be looking FOR even, so any help is much appreciated!

Thanks in advance
