Win11 unknown devices shown in device manager

Post by Gundel22 »

Hi, I have a running Win11 on my GK3, everything works fine so far.
I wonder why I see a yellow warning sign for devices called "SM-Bus-Controller" or "PCI Communication Controller" in the device manager. Can I get rid of that? Any special drivers required here?

1. Download the Intel® Driver and Support Assistant, it will automatically detect and update the driver after installation. Link:
2. Update the driver:
3. Reinstall the system.

@barry777 great, thnx. After Updating drivers with downloaded .7z archive, only SM-Bus-Controller is left over. I'll continue my research.

Did you use the first and second points? Tried rebooting after installation and still have problems?
