Those are installed when you install the Intel Chipset Drivers which should have been the very first drivers installed after loading Windows.  Without the chipset drivers, other drivers may not install or may not work.

You didn't mention the version of Windows so go here and select the right version of Windows from the list before downloading any drivers:

1. Intel Chipset Device Software
2. Intel Management Engine Components Installer Driver

Several versions of each may be listed so choose the ones with the highest version numbers, depending on whether or not you have a vPro system.

Then install any other drivers from the Support site that you're missing.

And please don't double-post the same problem.

Note the drivers at that link are probably not the right drivers if you actually have a 3020M.

Both of those drivers are INTEL CHIPSET

the PCI Controller is INTEL AMT HECI SOL  serial over lan

PCI Simple Communications Controller

this is the intel chipset driver

SM Bus Controller

If the usb ports dont work try using USB 2.0 Ports

if that doesnt works use a dvd to burn the Chipset drivers to a dvd-r recorded at 1X 2X 4X 16X max.
