i didn't use any AMD GPU，maybe is USB problem，because 4 USB 2.0 only can use one，3 can't use，but all USB 3.1 can use，thanks to help me！I think you’ll need to check some BIOS settings, as I no longer have the board I can’t remember my exact setup, but with that EFI everything worked perfectly except for NVRAM. Even sleep/wake, shutdown etc.
have you tried following the guide here, this has always been my first port of call and describes many of the common problems like this?
There are many things that could be interfering with shutdown/sleep main culprits could be usb devices or gpu’s, without having the board anymore it’s difficult to remember exactly what my settings looked like I’m afraid.
EDIT: I just noticed in your profile "GTX TITAN" - are you running an AMD GPU as well? If not, that is very likely your problem. And if you are running an AMD GPU as well as your GTX TITAN you'll need to properly disable it with an SSDT or Device Properties, I've found SSDT to be more reliable.
