Usn journal problems in windows xp

I keep getting, every few days, a slow start to win xp, which does its own chkdsk and turns up with some errors in the "usn journal" which it then fixes.

All very mysterious. After reading all the stuff below, still no idea how to prevent the problem. Do I re-install Windows?

Following websites discuss it but not very helpful

The usn journal is a log file of changes on your hard drive, you can delete it. at a cmd prompt you can type: FSUTIL USN DELETEJOURNAL /D C:
