Windows 10: Graphics Driver Problems After Accidental Uninstallation of Pci Bus (From Device Manager)

Hello to whoever is reading this!


I recently accidentally uninstalled Pci Bus from the device manager menu, after an update for it caused some problems on my computer. However, as you would expect this caused a number of other problems with other components of my computer; I was able to reinstall the Pci Bus software, along with my graphic driver software. Then I noticed there was a severe decrease in my performance, which led me to discover some changes to my AMD Catalyst Control Center, namely switchable graphics and 3D Application Settings. I am sure that there are other issues which I haven't identified.


Now I'm not sure what to do. I realise that I could do a system a restore, but I would end up losing a lot of data, so I'm keeping that as a last option. Since I didn't want to download software from the web "recommended" to solve my problem (as they could cause more harm than good), I decided to post this question here, in the hope that someone here may have a way to solve my problem.


Let me know if you need any information or pictures to help you.

Windows 10 Update KB4462919 1803 Breaks HPs AMD Video Drivers as Usual Due to PCI Bus Driver

HP hasn't updated its AMD Video drivers for my Pavillion 17 V0Q20UA AMD Laptop since 2017

The ONLY driver that works is in the SP77768 package from HP. Nothing else from Microsoft or AMD will work on this laptop and a similar situation is probably true for ANY laptop with dual graphics.

The problem is that pretty much every Windows update overwrites something installed by SP77768 and breaks much of the graphics capabilities of this laptop and causes issues with the PCI bus resulting in a warning at every boot that the PC needs restarting.

Every single time the user must:

Go to the device manage and uninstall the PCI bus, reboot and suffer

Then reinstall SP77768 and suffer

Hope for the best

Suffer with probable security issues with having a 3 year old drivers on your system
