If after you replace the motherboard XP won't boot, you can sometimes get it to work by doing a repair install of the operating system.
I understood the problem of the wrong drivers making XP unbootale. I suppose that I could try a repair install, but the last time I saw someone do that it messed everything up. Not sure what they did wrong though. I, myself, have never had that problem and therefore I do not know enough about the process to be comfortable with that at this point.
You might wish to read this article on moving a hard drive.
You could install the hdd in another computer as a slave drive, assuming it's IDE connection, and transfer her files to CDs or DVDs.
As I had stated in my original post, the files are encrypted by windows XP's user profile preferences. It is a SATA drive, but this is unimportant. The problem is that those files, being encrypted, will not be accessible from another computer (unless you know something about XP's encryption that I have not learned yet). However, having scanned that link I think it might give me the guidance needed.
