After such a major hardware change (motherboard+cpu) it's always recommended to do a full reinstall.

Also, if your Windows is oem and not retail, you may have to purchase another Windows license.

What OS is it?
If Win 10, read and do this before you change any parts:

That's for the licensing/activation.

For the install, a clean install is strongly recommended, usually required.
