    Hi all,

    I've been having a problem with my PowerBook the last couple of months where I cannot turn the computer on without a kernel panic. I can get past the Apple logo at boot before this happens. I've tried everything, including the various boot options and it always reboots into a kernel panic. Does anyone have any ideas? Thanks!

    Is this all booting the same OS install off the same drive? Kernel panics are usually software related, so if you can try booting off another drive or OS install, you should just to see if you've got some data corruption going on.

    You can try booting in "safe mode" by holding down shift. If that doesn't work, try single user with command-s. If that boots, then it may be the GPU is bad. Might also try taking out the airport card and see what you get.

    I have used this outlined troubleshooting process linked below.

    1. Safemode
    2. Update soft/firmware
    3. Verify disk health
    4. Remove peripherals
    5. verify RAM sticks


    For me, it was a bad stick of ram in a 06 intel white iMac I purchased 2nd hand. The box started acting like it was possessed. Testing each ram stick individually showed a faulty stick was causing the kps. Anyhow, replacing both sticks with Apple certified crucial ram fixed it. The above process is solid for crossing off what isn't causing the kps until you find the cause. Good luck.
