The title is not quite accurate. Whenthe computer is shutdown and turned on, it completes the POST and stops at a flashing cursor. At that point I can press the power button (not press and hold) and the computer will power off.
If I press F8 I will get the appropriate menu and I can boot to Last Know Good Configuration. I can then reboot adn everything appears normal.
Until I shut down the computer. Then I get the same flashing cursor.
Nothing shows in the event logs.
Hardware diag show nothing wrong.
SFC /Scannow showed nothing.
User can usee the computer without issue until it is shut down.
