HISTORY:
Starting on late evening Jan30/06, a message box showed up in the lower right side of task bar saying a chkdsk needed to be done. The message mentioned something about ICQ (ICQ is on the computer but hasnt been accessed in a few months).
I was told about the message 1&1/2 hours after it appeared; I clicked the 2 boxes in the chkdsk window from "tools", & restarted the computer so the chkdsk could run.
As soon as the chkdsk started, in the first section, all of a sudden there were "tons" of files scrolling down as if being added or accesssed. The chkdsk continued & finished.
