Network Adapter missing after reinstalling Windows 7 64bit

[mssjaney]

I've just reinstalled Windows 7 and my whole Network Adapter is missing. In BIOS it is indicated as '! Network Adapter'

When I downloaded Network Drivers from the HP support website and tryed to install it, I got the message 'system not supported'. I also installed HP Diagnostic Tools and run it in UEFI boot mode but got the message that the network component test passed.

In Computer Managment I have a number of yellow exclamation marks and  Hardware IDs are as follows:

Ethernet Controller:

PCI\VEN_10EC&DEV_8168&SUBSYS_81EF103C&REV_15

Network Controller:

Hope you can help me.

What model 250 G is it?

There is no such thing as a Gp.

G3, G4, G5 or G6?
