Unknown PCI Controller device

dejot — Thu, 24 Nov 2022 17:00:47 GMT

Hello! After fresh installation of Windows 11 Pro I am getting this in my device manager.

Notebook: MSI GL65 9SC

CPU: Intel(R) Core(TM) i7-9750H

IDs of devices taken from device manager:

PCI\VEN_8086&DEV_A323&SUBSYS_12A11462&REV_10

PCI\VEN_8086&DEV_A379&SUBSYS_12A11462&REV_10

PCI\VEN_8086&DEV_A324&SUBSYS_12A11462&REV_10

Any ideas?

Go to the support download site for your system/motherboard and install their chipset inf.

I installed that

Nothing changed after that.

No, that's the ME driver package. You need the Chipset Device Software package (a.k.a. INF Update). I don't see one in the downloads are you linked, however. Time to call MSI and ask them where it is.

If you have to, you could try using one of those available in the Intel Download Center; look for one for an Intel NUC product that has a processor similar to yours.

Hope this helps,
