Thank you for joining the Intel communities.
You don’t need to remove the Intel® graphics driver to install the Nvidia card and that will not cause conflict, once you install a video card and you have it up and running the onboard video will be disabled and only the Nvidia card will be active.
If you reinstall Windows you don’t need to install the Intel® graphics driver because you will be using the Nvidia card only, but if you decide to install the Intel® graphics driver you will need to install it first before installing the Nvidia card and that will not cause any problems if you have it installed.
Ok, thanks for the answer.
You’re very welcome!
