<br><font size=2 face="sans-serif">There have been no hardware or software
changes on the box since Feb 13th when I installed a new hard drive. I

I shut the box down for about half an hour. When restarted,
the problem did not re-express itself for about two hours. Time to
buy a quiet case fan.</font>
