Nan Ominous, are you using the correct shut-down method of. Start/Turn off computer/shut down from the on-screen controls?
If you are using the power button on the front of the PC to shut down, then go to control panel/performance and maintenance/power options/advanced, and select the option you wish the power button to perform.
"When I press the power button on my Computer"
Select [Shut down].
Hope this is of help. j.
