You have a custom-built PC with a retail motherboard - using an OEM_SLP Key from a Lenovo machine.
This can only be activated if the installation also has been hacked to bypass activation/validation requirements.

The installation is therefore counterfeit.

You need to reformat and reinstall using genuine media and Key
