When I boot win 10 it runs for a few minutes then shuts down. No BOSD.
Reboot & everything is OK!

I can press & hold the start button until the light goes out & reboot again & again, but if a shut for a long period it happens again!

One of the fixes is to run a command using Command Prompt under "Administrator!.
The instruction say to type in "Command Line" then choose "Administrator".

When I do that, it goes straight into the command line without any choices!
