Hello, how are you?
My name is Paloma B., I am very happy to be able to try to help you in the best possible way.
I understand that you have questions about replacing your computer's motherboard.
The backup is simple, you should simply copy the important files to an external disk for example, that way the data will be safe, so that you can return them to your computer's disk in the future.
Yes, the drivers will need to be reinstalled as each motherboard has its correct drivers.
In this case you will need to go to the manufacturer's website and search for the correct drivers for your motherboard model, it is important to update all available on the website.
Did an error occur while copying the files?
Anyway, changing the motherboard doesn't directly influence the hard drive.
Some people choose to simply switch over, and install new drivers, if they don't have any problems, they don't reinstall Windows.
This way, neither file nor Windows itself is affected, remaining the same.
This is optional though, you may not do a clean install of Windows to your disk.
What exactly appeared after replacing the motherboard? could you share a photo?
I await news.
