My computer meets requirements for nightfall.
While it lets the game run it runs fine.
After thirty minutes or so the game crashes to a black bluish green screen where after seeing the screen, I am forced to restart.
What could be causing this?

It would be useful if you posted some more information, like your system specs and what you're doing/where you are at the time of the crash.
