|I'd consider Microsoft's suggestion to perform a ntbackup with system state. Then install xp as clean new format. Then apply the restore of ntbackup. |
There is a small difference between system state and not and you may wish to choose which suites you.
Not sure you do need to do all of that. Some repair and other fixes like sfc.exe may help.
One of the problems with XP and other Windows is if you have malware or other data issues they can be replicated in any restore. They may not be corrected on repairs either.
I tend to simply do a full install from all my original disks. It always seems to work and always makes the system new and fast again.
Why did it take me over a year to phone in a problem to ATT?
