Sorry that it was not something that we could offer any repair for but you are welcome
Can I just mention something, as you are going to need to replace the MB you will need to reactivate Windows when you fit the new board, not a problem if the Windows 10 product key that was used with the MSI board was the full retail type but if only the OEM/System Builders type product key you should contact Microsoft to let them know that your MB has failed and that you will need to reinstall Windows using the same product key, they are pretty good if you notify them first but you can have problems if you do not.
