Dear Wise-List:<br><br>My 500GHz Sawtooth, 1 GB sdram, OS 10.3.9, external LaCie FireWire 120GB, esternal Maxtor USB 160GB, 17" flat Studio monitor, is sometime cycling on-off.<br><br>The "on" button on the computer case stays lit, I can hear the CPU powering down, then up, then down, and last time, the monitor went dark and I had to pull the plug.<br>
<br>When I booted up today: all OK.<br><br>Ran Disk Utility and TechTool Express: all OK.<br><br>What is going on?<br><br>I have everything backed up to the 2 external drives, but still: this is a resuced unit, all thrown out (!) and it has worked flawlessly for 2 years, and I want to keep it up and running until it is glowing plastic dust.<br>
<br>Thanks!<br><br>PMW<br clear="all"><br>-- <br>peter m. webster<br>
