Sierra install on Gigabyte Z170x-Ud5 no audio, ethernet, Gtx 950 nvidia driver not working

Hello, I followed the instructions to the T and mostly everything worked & installed the drivers included in latest multibeast for sierra, the Ethernet port lights up as receiving signal but not working, same with audio , installed driver assigned for this Motherboard it's not recognized, and after making changes with Clover configuration mounting partition, still not recognizing Nvidia driver.
Please help, this is my 1st build, and would really appreciate any help I could get!
happy new...
