Your operating system does not want shut down properly? This is probably due to a problem related to the power management (APM: Advanced Power Management).
- To handle this problem, we must first ensure that the APM is enabled in the BIOS of the computer, and then enable it under Windows:
- Control Panel/System/Hardware/Device Manager/ View/ Show Hidden Devices
- Then look for the NT APM/Legacy Interface Node and activate it.
- Control Panel> Power Options> APM> See that box is checked.
- Otherwise, you may install the new device with the Windows wizard.
- Start, Run, type "regedit"
- Type Ctrl + F
- Search "PowerDownAfterShutDown"
- Set its value to 1 and restart the computer.
Note that on some equipment (often the first ATX compatible computers) may experience several issues with the Advanced Power Management (ACPI)
