your defrag program may have been corrupted. try using system restore or try using the windows xp recovery console on the xp setup disk.
Reply:You can try:





Start%26gt;Run type "sfc /scannow" without the quotes and make sure to put the


space before the /.





If you have your original CD and Serial do the following. **NOTE** if you don't have both please do not continue.





Insert the CD. Restart computer, boot to CD. At the first screen continue with install. In the next window use the repair option. **NOTE** DO NOT use the first repair option and DO NOT reformat disk.
