I recently upgraded my PC and switched MOBO and CPU to activate windows again it come up with a screen saying Microsoft Account is the TAB and Oops - Something went wrong This service isnt available at the moment, please try again later.
Is there a FIX

Is the system able to connect to the 'Net otherwise?

Likely, you need to first install the lan drivers for your new motherboard so windows can connect to the activation servers.

clean install is normally best answer if you swap CPU & MB.

On another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB (if you don't have one)

I would clean install. Since your user is a Microsoft Account, we can hope the licence for install is linked to it.

after install, run the activation troubleshooter to move licence - https://support.microsoft.com/en-us/help/20530/windows-10-reactivating-after-hardware-change
