This is one of the enduring problems of Windows XP.
I've found on numerous occasions that trying to install from an original XP disk fails because XP2 and XP3 software is, basically, incompatible
Savvy folks will keep an up to date copy of XP on disk with all the add ons so that they can reinstall
Some others will wipe the drive and start again with, perhaps, 24 hrs of installing updates to get them to where XP is now
No chance of trying System Restore I suppose?
