(Redirected) Inspiron 15R 5537 can't restart\reboot with Windows 10

Hello,

Ever since I used Microsoft's MDT 2013 to install Windows 10 on this Inspiron 15R (5537), the laptop no longer successfully reboots....  It exits fine out of the current Windows 10 session, but never fully boots back up.  All I get is a blackish screen in which keyboard\mouse inputs don't work.  If I shut the laptop down all the way, it starts back up fine....  Device Manager doesn't show any missing drivers.

Anybody have an idea why this is happening?

Thanks!

Adrian
