Win8 can not shut down the cause and solution

Windows 8 system can not be shut down for the following three reasons:
a: After clicking Shutdown, the monitor screen is off, but the host is still running
Resolved: Try to disable the Hybrid Boot function. You can use the “shutdown.exe -s -t 00” command to create a shutdown shortcut button on the desktop, which can also be solved!
b: Staying is shutting down and you can't shut down.
Resolve: Maybe a process is stuck, can't close, at this time press the taskbar manager and exclude one by one.
c: Automatically restart after shutdown or blue screen
Resolved: It may be a driver or hardware compatibility problem, try to uninstall the driver to exclude.
