Hi Macintoshlady. It is frustrating when you can't figure something like this out. In my experience, many kernel panics are caused by faulty RAM, even RAM which worked fine with previous systems. It seems that OS X is getting progressively more finicky about RAM spec's. Try running the Hardware Test CD that came with your Mac and do the extended test for memory. I found that a chip that had worked for over a year with all previous versions of OS X no longer worked somewhere around 10.2.6. Fortunately, the vendor (18004memory) offers a lifetime warranty and sent me a free replacement module. Good luck.
