How to make the integrated video card work in i7 without touching the additional AMD?

Question

Iron

In general, this is the case: I had a computer with a built-in video card ( Intel® Core™ i7-3770 ). I bought an ATX card, inserted and installed all the drivers. It works well, but now the old video card is not visible even in the Device Manager. Plugs from it do not work.
As I understand it, the installation of ATX drivers wiped out everything that was from nVidia in the system ... And I need to periodically connect a monitor to it.
So, the question is: what happened to my old video card. How to revive it again and start using it.
Thanks in advance.

Answer 1

Everything is quite simple - when booting into UEFI, the priority of video devices is configured. In your case, it costs PCI-E / IGP, i.e. when the video card is installed, the built-in video turns off and is not visible in the system at all (therefore, the drivers will not become, since Windows will not see the device).
You can either pull out the video card if you need the integrated graphics, or set the priority to the integrated video.
What is the motherboard, by the way?

Answer 2

We do a rollback of Windows - system restore and return to the moment when the video work from i7. Of course, just in case, we make a copy on a removable medium of the data you need.
Maybe there is a second option.
We demolish the drivers related to the process. And reinstall again. Try it.
