GoBack is usually quite finicky about other 'similar' programs & could conflict with System Restore (though I have to admit I've not tried it on WinXP).
GoBack is easy to use & works well when it does, but if something goes wrong it could mean a reformat/reinstall, which I found out the hard way.
I would suggest you get a disk-imaging program like Acronis True Image 8.0. Norton makes a similar program called Ghost (9.0 is the latest version), but I've heard True Image is easier to use. G
