DangerDillard, I have the exact same problem. I followed the method 2; revealed hidden items in device manager, saw my Nvidia GTX 960M, uninstalled it, and restarted the computer.
Now I have no traces of the Nvidia video card, even when I reveal hidden items.
Yesterday Windows 10 automatically updated my Nvidia driver to 361.75, and in the middle of the install crashed to a blue screen. Subsequently my multi monitor setup wouldn't work, so I started looking to manually remove and update the driver for the Nvidia card.
