Here is the support page for Windows 7 drivers

https://support.hp.com/us-en/drivers/selfservice/hp-elitebook-8540w-mobile-workstation/4096175

Since that PC cannot connect to the internet, use a different PC and download drivers to a media choice (either DVD or USB flash drive) and then install them to this PC in question.  Start with the chipset drivers first.

Hi, @imsanaga1

Specifically, you need this driver for the PCI Serial Port and PCI Simple Comms Controller:

Intel Management Engine Components Driver and Interface:

The unknown device probably needs this driver...

HP 3D DriveGuard:

The info at the link below has been very helpful to me (100% effective) when my W7 PC's had issues with Windows update.

I never had to click on the Advanced users discussion link.
