Re: Aurora r6 restarting when told to shutdown.
as you already noticed there is no simple answer. so we have to dig around.
we are talking about Windows 10, right?
latest Windows Updates installed?
have you tried to re-install Chipset Drivers?
the latest BIOS Version installed?
also BIOS reset might or might not help. but worth trying.
open Start Menu, hold Shift and click Shutdown. does your System restart again?
