Even with Windows 10 you cannot expect it to run properly after a switch from an AMD motherboard to an Intel. There are just too many differences in the hardware. Unfortunately from what I have read, if you switch out a MB the the Windows 10 digital license is no longer valid. Because you upgraded from Windows 7 to 10 you have a digital license stored on Microsoft servers that uses a hardware ID.
There is a possibility you can use your Windows 7 pro key during the clean install. There has been some talk on the internet that Microsoft is still activating installs with a genuine Windows 7 or 8 key even though the free period is over. If activation fails then contact Microsoft directly. Ask for a live person and explain why you needed to install a new motherboard. Microsoft is pretty generous at transferring licenses if you give them a good reason.
If you live in the States contact them at (888) 571-2048 and ask for a live person.
The Media Creation tool will create a DVD or USB install for Windows 10
Make sure all your personal data is backed up. At the screen that asks for language press Shift + F10 to open a command prompt. Type the following commands. I am assuming the new MB is UEFI.
select disk X Where X is the number of the disk you will be installing the OS to, usually 0.
clean Deletes all existing partitions
convert GPT Initializes the disk as gpt for UEFI computers.
exit exits out of command prompt
exit exits out of diskpart
continue with the install
Edit: You can use any Windows 7 or later computer with the Media Creation Tool to create your install media.
