W10 wants his graphic card !!

Hi !
I have a strange problem (in fact the opposite of most cases on the forums!): If I remove the graphics card and connect the monitor to the graphics output of the MB, w10 refuses to boot, it will puts on "automatic repair", turns off and it starts again.
I first thought it came from bios, actually the "detection graphics" option was on "auto", so I put "internal graphic" on "enable" .. it didn't change anything, except that I was able to put two screens, the new one (4k) on the output of the mb in hdmi,
and the old one on its graphics card (in fact the output of the MB is better than the old card!, that's why I wanted to remove it)
There I was able to boot w10, and I put my new screen in main, uninstalled the old one, uninstalled the GC and its drivers ... turned off and dismantled the GC.
In terms of bios, no problem but as soon as W10 launches, it reboots continuously, sometimes with "automatic repair" ...
It looks like windows has memorized once and for all that it should boot on the GC! Besides, with the two-screen config, that's what it does, it boots on the CG and after, it puts the requested config with the output of the MB on the main screen.
And also, impossible to have my main screen (MB output) in N ° 1, it is always spotted by windows as N ° 2
I would like to remove this GC and the old screen, but impossible !!
Ideas would be welcome !!


Proc: Intel Skylake Core i7-6700K processor 4.2 GHz 8MB
MB: Gigabyte GA-Z170X-Gaming 7 ATX

I've never seen anything like that.

You could try DDU (Display Driver Uninstaller Download version 18.0.2.2) to see whether it removes remnants of the unwanted graphics drivers. I'm not sure how safe it is, as it removes Windows Registry entries, so I'd back up (image) the existing Windows installation first.

Ultimately, you may be forced to do a clean install of Windows 10. I've gotten to where I can do that in a few hours, after a little preparation.

Best of luck.

total uninstall of nvidia with ddu / shut down / dismantled the GC / restart ... It doesn't work ;(
The behaviour is exactly the same
Perhaps a problem with the internal graphics .. But how explain the output works fine when the GC is connected, and the display of the bios works fine also when the GC is not connected ??!
I think it comes from windows .. It happens after a few second of booting , after the bios.
Also : 2nd try : I used DDU in safe mode, keep the two screens, and forget to reboot in normal : only the output of the GC worked, the 2nd screen remained black
???!!!

You are aware that the motherboard usually disables the onboard graphics when a discrete graphics card is present, right?

Yes !
But there is an option to enable the internal graphics in the bios, and I selected it.
Then the two graphics can work simultaneousli ( only when the GC is present ;(
I have a good 4k screen on the output of the MB ( windows says N°2) , and the little old one on the GC ( N°1)

The GC is : GV-N62-512L geforce 6200 ... But Idoubt the problem comes from it, because if not present, the system bugs !!
Perhaps a repairing of windows !!?? but I dont want to lose the datas and the config .. I prefer stay with two screens !!

You can repair/renew windows system without loosing anything.

I tried this process : YouTube
The answer is : " cannot repair your system"

(that's logic, cause I made this with the two screens plugged, so everything works fine, nothing to repair !! )

From a boot medium? You can keep your files, but nor your apps, as I have understood it.
