Hi thenerrus,
If you have a display on your laptop, the VGA is working. I seriously doubt you have two different video cards in that lap because they're not usually built that way, unless you had another on installed. The information you provided says you have an Nvidia card as your video adapter, trying to install the Intel drivers and having them fail also says you only have an Nvidia adapter installed.
So, unless you installed another video card or unsure what card you have installed in the laptop, I would suggest you look up your systems specs from the notebook manufacture and see what card is installed on the machine.
Good luck.
