Once you move the files, you will have to also delete iTunes Library.itl & iTunes Music Lbrary.xml, and when you start back up iTunes, it will rebuild those two files. Keep in mind this has worked for me, but may not work for you.

Also, only way the PC would slow down is if iTunes is up and running, and she is "sharing" her music, otherwise if it is not running in the background, it will not slow it down. I would go through and Defrag the computer, and do a Disk Cleanup, and start from there.
