Need to re-enable graphics card

[Nickkk]

My Computer was running dual graphics cards, but has low RAM, so i disabled one in order to free up some RAM. After doing this, my computer will boot-up, but after that there is no display. I need to know how to enable the card that I disabled in the Setup screen, or whatever else may fix the problem.

Easiestway is to pop one out and boot up, then put back the 2nd one after you set thngs up.

Ok, that helped the black screen, but now how do I set up my computer for 2 graphics cards again?
