Hey there

I have no idea what any of this means or if it can "point me in the right direction" as to resolving the issue (a bad CPU, RAM, disk, etc.). Here's the text from my panic log:

Any info/tips/ideas would me much appreciated,

Maury-

I don't know. That aside, *g* have you run fsck, tried to remove a RAM module at a time, tried the disk Utility from the OS X install disk?

You probably are way ahead of me on this. I do not see the mention of any I/O devices in the log. I don't think the CPU is suspect because you are getting a coherent crash log.

Just some thoughts.
