Hi--I have an XP SP2 computer that began having a mysterious and deadly
problem. Windows boots fine, but then clicking on ANY program starts the hard drive accessing continuously, and the given program won't load. This is true of every program I've tried. I've tried booting into safe mode and going back to previous system recovery points, but the problem still occurs, rendering the computer virtually unusable. (I'm talking about Microsoft programs, non-MS, Norton, Adobe, you name it).
XP has been updated regularly. It ran fine on the day of the problem for about 4 hours before it started to crump. NAV 2006 had run its usual weekly virus scan without finding any problems--the scan finished about 1 hour before the problem started.
What steps should I take to try and diagnose/fix this problem? Help would be much appreciated.
