You don't have an actual video card on your laptop. Video is integrated on the motherboard even if it is from Nvidia. Your drivers must come from Dell not Nvidia since drivers are customized for your board. Go to Dell Downloads to get the drivers. You can see if Dell has drivers for windows 10 on your model. If not, the previous video driver will probably work if the laptop is not too old. You were better off not upgrading to 10 if the computer is over 4 yrs old and has not been approved for the upgrade by Dell.
