... after shutdown or restart

[inbox]

The case is that after restart o shutdown OS X my hackintosh properly is 10-15 seconds with the led´s on (the monitor is off) and after that the system power off or restart.

My system is:
Gigabyte Z97N wifi
Nvidia 970 GTX
Dual Boot MacOS Sierra and Windows 10

any help or idea?
Thanks in advanced

update: after remove FakePCIID.kext and FakePCIID_XHCIMux.kext everything is fast and ok.
is there any way to get full USB 3 support without these kext?

If you are using clover then try 'Halt Enabler' (Put a check) to see if it fixes your issue.
