Hi:

The thing I don't understand is that W10 should have automatically installed the Wi-Fi and ethernet drivers.

Download the following drivers from another PC, copy them to a USB flash drive.

Intel WLAN Driver 

sp141851.exe

Intel Bluetooth Driver

sp141045.exe

Intel NIC Drivers

sp135655.exe

Plug the flash drive into your 840 G3, copy the driver files to your Windows desktop and run the files to install the Wi-Fi and ethernet drivers one at a time.

If you need to reinstall Windows, you can use the HP cloud recovery client software on another PC to create a bootable USB recovery drive that will reinstall Windows  and the drivers that came with your PC.

Here is a link for how to use the cloud recovery tool.  You will need a 32 GB USB flash drive for this.

Pay particular attention in the section for how to install the drivers after Windows is installed.

You can download the software from the link below:
