    I began having freezes unrelated to any new software or behaviors. The hardware check showed no problems with the hardware or memory, so I cleaned out the inside of the computer, used Disk utility, AppleJack, Mac Janitor and reset p ram (all said it was OK, then the freeze came back), and finally zeroed the hard drive and reinstalled OSX.

    It was stable for a few weeks then the freeze happened again followed by repeated kernel panics. I went thru all the steps above again but finished with an archive and install and created a new user admin account. Until this point the freezes and KP were on all three user profiles. But now this new user admin is fully functional while the others are still messed up.

    Can my other profiles be corrected? how do I stop the KPs? What is causing them?

    I have a set of two unopened 1GB Kingston ram should I replace the factory installed ram with them? Should I add them to the mix?

    Does the presence of a clean user profile mean that this is not a serious problem? If I create three new user profiles, can I transfer the items purchased from iTunes to the new profiles, or will I loose all that stuff as it is authorized for that profile?

    Thank you in advance for any advice/help that you can give me. I love my computer and need to get this back in working order.

    This is a copy of my KP log I don't know what this means:
