Hi,
I'm using a Hp 17-f067nf laptop with an Intel integrated Graphic card and an Nvidia 840m as a dedicated 3d gpu. 8go of ram, 1tb of Hdd
Long story short:
I wanted to uninstall my gpu Driver to roll it back and i accidentally uninstalled the gpu itself in the device manager and now it doesnt appears even after restarting the computer.
i tried rebooting, updating bios, downloading Hp Driver, multiple restart, using DDU on safe mode and uninstall the Intel gpu Driver... nothing works.
I checked the laptop entirely, opened every part that i could (except the gpu 'cause it's glued) and nothing was damaged, i even removed the cmos battery and put it back on, system restore is no longer an option cause the ddu point is no longer available.
On the other hand i've noticed in the device manager that the Intel 8 Series PCI Express Root Port #5 appears to be disconnected and when i look into the exact same computer (my brother has the exact same one) the nvidia 840m is on the #5 Port..
In the end i'm stuck with an uninstalled gpu who was working perfectly fine so far (like 10 min prior to the rollback).
