Missing PCI and SM Bus Controller Drivers After Reinstall

[my_eyes_hurt]

I have the OMEN Obelisk Desktop 875-0xxx.

I just reinstalled a fresh copy of Windows 11 (it previously had Windows 11)

I ran the automatic drivers diagnostic from the HP assistant and it only recommended a BIOS update.

However, I have the following missing drivers when looking at Device Manager:

1) PCI Data Acquisition and Signal Processing Controller

2) PCI Device

3) PCI Simple Communications Controller

4) SM Bus Controller

What specific drivers do I need for these devices? Device Manager cannot locate them by searching the internet. I don't want to just start installing drivers randomly.

Someone please help!

Hi:

This driver should install the SMBus controller and the PCI Data Acquisition and Signal Processing Controller devices you posted...Restart the PC after installing the driver.

This package contains the Intel Chipset Installation Utility and Driver for supported computer models and operating systems. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager.

This driver should install the PCI Simple Communications Controller:

This package provides the Intel Management Engine Interface (MEI) Driver for the supported desktop models and operating systems. The Intel Management Engine Interface enables communication between the host operating system and the Intel Management Engine firmware.

If any device still needs a driver after you install the above two drivers, please post the hardware ID for it, so I can figure out what driver it needs.
