That might be the problem that the driver of your other graphics card only works with the graphic card that comes with it. Use the other graphics card to download the nVidia driver of your model from there website http://www.nvidia.com . After the installation of the nVidia driver is finished, shut down the computer, open the covers and change the Intel card to the nVidia card.
I hope it works!
