    You CANNOT use an OEM License (from the COA sticker) from one computer on another computer.

    Replacing the motherboard on a computer outside the warranty conditions invalidates the license.

    OEM Licenses are non-transferable.

    You'll have to purchase a new license for Windows, or revert back to the original OS on the system you're currently using.
