Dudes,

  I use disk cleanup and defrag on occasion but today trying to use disk cleanup it starts compressing files then stops. Just sits there and when I cancel disk cleanup the computer gets very SLOW!  A reboot sometimes restores its' usual vigor sometimes not. One reboot generated that famous "sending error report to Microsoft" message. Current NAV and Spybot scans are clean. I guess I just won't use disk cleanup but I'd like to. Windows XP Dimesion 4400

   Thanks, Dave
