Mike is having an issue where Windows is just flickering. All he can do is shut down and reboot. It could be a bad update, so Leo recommends downloading a clean build of Windows 10 from Micorosoft with the Media Creator Tool. It will build him a key that he can put on USB and then wipe his hard drive and start over. That could fix it. If it doesn't, his computer may not be compatible and he may need to install Windows 8 instead. If that doesn't fix it, then there's a hardware issue. But a clean install should solve the problem.
