Os Alternately Freezing And Unfreezing

Hi,
I installed two differant linux systems on one computer at differant times in the past year, and had a problem with the system freezing and unfreezing every five seconds or so, after I updated the initial install. I finally ran across a fix for the problem, here it is:

Open a terminal

Su
Password

kwrite /etc/rc.conf

save a copy of the file to your user home file

in the file find powerd_enable="YES"
change it to powerd_enable="NO"

in the kwrite file drop down menu find save as, and save the altered file as /etc/rc.conf

reboot the system, or maybe just log out and back in, I rebooted.

The freezing should be gone.
