Rick,

There were no resource hogs in "ps ax" or "top".

It wasn't "updatedb".  "DAILY_UPDATE" was no. I have been booting the 
machine at least once a day
since I installed on January 16.   BTW,  I love "slocate".

I turned off acpid first by stopping the service; things improved 
dramatically and instantly.  
Then I chkconfig'd it off.

I want to boot with "noacpi".  Where do I put that? 

Thanks,

Brenda
