Yes, good 'ol XP, cause it just crashes all the time for no reason. Never has anything to do with faulty hardware, or being loaded down with shoddy software.
What exactly is it doing when you turn it on? Does it post (the beep during bootup), does it get to where it's loading windows? Does the hard drive tick? Does it even power on?
Data recovery is a tricky issue. If the hard drive is fine, it shouldn't be a problem getting the data (unless her files are "locked" inside her profile). However, if the drive is dead, there's little chance of getting anything off it ... not without a few thousand for professional data recovery services (which also don't guarantee that you'll actually get anything).
There's also the possibility that it's some other hardware. And a good chance it could just be all the random crap your girlfriend has installed... maybe she got a virus.
