So you did not have any luck with the Intel .exe chipset driver install package? This should install your PCI, Ethernet, USB, and SM Bus drivers. Of course you may need additional Ethernet drivers as well though.

Just be sure you are downloading the .exe installer file and not the zip file.

If you want, please install a trial of everest ultimate and save a complete report, then tell me which drivers are remaining in device manager that are missing. You can get a copy here >>
