Hi Carolyn and any other interested listers,
Well it's been interesting trying to fix these issues. Many experiences of the past week are pointing to hardware issues.
I tried to back up my HD expecting the worst, but couldn't get through the process of Restoring (cloning) it to my external FW Disk using Disk Utility ( a task I've done forever without isses).
So I got out the original PBG4 Hardware test and it failed during the "Memory Test." Next I removed the 1 GB RAM chip from the computer and re-ran the Hardware test twice with AOK results, so I am assuming the soldered on RAM is not the issue.
I was able to run the computer from a Disk Warrior CD, and thought it might boot without anything but the onboard RAM, but no go. It kernal panics without any additional RAM installed. Doesn't the Mac need at least 512 MB of RAM and that would explain it, or should it be booting. (Mac OS Leopard X.5.8 installed).
I guess I should get a replacement 1 GB Chip.
Could it be bad contacts. How does one clean the contacts on a RAM Chip.
Thanks in advance, and so long for now, TOM
