Thanks so much for all the help! I'm gonna be pretty busy today so I won't really have much time to try and play with her computer but I'll let her know to try to use it as normal. Hopefully it will be stable and work out fine, but if it crashes again I'll take a look into it and post here if I can't figure it out myself.
You guys have been awesome. I'll follow up in a few days to let you know how the computer is going (hopefully I'll be able to close this thread with a "Solved" prefix).
