A factory reset returns the OS to it's original configuration with all the original drivers installed. Those drivers won't work and Windows will likely blue-screen because the old motherboard is no longer present.

That depends on what "data" you're trying to retain. Any installed programs will be lost when your reinstall the OS. Any data files (documents, audio/video files, images, etc...) will need to be moved to a different location (another computer, another hard drive, or a separate partition on the same hard drive if already set up) before you reinstall the OS.
