Unfortunately, there’s nothing available to preserve all your programs and files.
You can store your information on an additional drive or a separate hard drive. What I mean is that after replacing your motherboard, your existing operating system won't function anymore. You'll need a different one. If you decide to clear everything during the installation or just the system area, it's entirely your choice. In summary, yes, you can protect your data and avoid losing it.
I’m preparing a backup of your data to an external SSD at the moment. If you upgrade to new hardware and switch from Windows 8 to Windows 10, will your existing files still be available on the SSD?
