Drivers in Device manager NOT able to update for HP Z4 G4 Workstation

[Amjosh]

Dear Community, i am unable to Update the following drivers in my Device Manager for HP Z4 G4 Workstation

- Base System Device
- PCI Data Acquisition and Signal Processing Controller
- PCI Device
- PCI Memory Controller
- PCI Simple Communication controller
- Performance counter
- SM Bus Controller
- System Interrupt Controller

Meanwhile, I tried to update the driver manually, but there was no success.

Please do you have any better option in routing this issue?

Is there any drivers which will help in updating all these issues at once?

Thank You.

Josh

Typically those items show as missing because of a new Windows install and the installer missed some basic required drivers.

If you are install Windows 10, the drivers are here

https://support.hp.com/us-en/drivers/hp-z4-g4-workstation/16449890

Start with the Intel Chipset drivers and then Intel Management Engine drivers and software.  That should at least get you started.

If installing Windows 11 or some other version, click on the "Choose a different OS" up by the "Selected operating system" just under the HP Z4 G4 Workstation heading, for the appropriate version of drivers.

If you are still having problems I linked @Paul_Tikkanen as he is much more talented at these things.
