I tried everything and then just before throwing it out and buying a new one I tried removing some third party ram: bingo. That was the problem.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Jim</DIV><DIV><BR><DIV><DIV>On 27-Jul-05, at 3:38 PM, David Flory wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">My understanding is that kernel panics are more often the result of some hardware problem. In my personal experience, the only kernel panics I've had were due to a faulty USB hub or a bad memory strip. See if you have the problem with no USB items except keyboar and mouse. If you have the Apple hardware checking disk, try running that. If comfortable with swapping memory strips in and out, try that too.</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Fair winds and happy bytes, Dave Flory</FONT></P> </BLOCKQUOTE></DIV><BR></DIV></BODY></HTML>
