Black screen after nvidia driver update

Hi! 

So after buying my X51 (I7 3770 with GTX 660 and 8gb RAM) a few weeks ago I decided to update the video drivers, so off to nvidia I go and it asks me if I would like to use the experience program, which I do. 

I start the process off, and half way through the screen goes black, but I leave it for about 10 minutes thinking "If I leave it then any installation process going on will finish" so I waited and turned it off. Go to turn it back on and still the screen is black. Now I can't do anything with it now because I can't get into safe mode and do anything without a display and I can't use to onboard HDMI because that is disabled. 

Is there anything that I can do to fix this problem? 

I'm not afraid of opening the case if I need to.
