I have replaced memory to another slot, with 128MB, renamed the CATROOT2 dir in system32 dir to catold, pulled all non-esential cards, tried 3 different xp home CD's...replaced the CD drive...the repair gets to 39 minutes remaining and stops and still get the Error The signature for Windows XP home Upgrade is invalid. The error code is 426.  Any more suggestions...I can not format the drive...I must keep the data.
It is hard to believe this is not in your knowledge base and there is no fix.
