    I need advice for my macbook pro that has an intermittent fault. Sometimes it will just freeze, and a grey screen will drop down asking me to reboot the computer (Kernel Panic).

    As I do reboot the computer it starts up until the apple logo on grey backgrounds and kernel panic again. I am asked to reboot again. There I reboot a second time and the computer will refuse to boot (black screen) with an S.O.S signal (3 long 3 short 3 long beeps) or a Bad memory bank signal (3 short beep).

    When this happens I have to open the computer remove and replace the memory in their slots and the computer starts again as if nothing happened.

    I bought new ram and new hard drive hoping it would resolve the problem, but it's still happening. When I went to an apple certified reseller to assess the problem they did a full hardware check and could not find anything wrong. I also tested myself extensive hardware tests (stress test of the CPU for more than 12 hours, stress test of ram for more than 12 hours) and everything seems fine.

    Though I have to admit that during a conference the bag in which I put my laptop broke, leaving the macbook pro falling of about a meter and denting the left bottom corner (the one towards the battery light indicator).

    I really don't know what to do or test anymore. Has anyone any idea of what I could try / do ? I don't feel safe working on my computer as It can crash anytime. I do have apple care and it's still under apple care warranty.

    Any comments or help will be greatly appreciated.
    Best Regards,

    have you verified the startup disk to ensure it's functioning properly? have you also considered wiping it completely and reinstalling the OS, not just cloning your current install if you havent already when you swapped the drive?

    scheduling a genius bar appointment is your obvious next option, and dont leave until the issue happens in front of the technician. even better is if you can get it to start causing problems shortly before the appointment so they can watch it in action. it's difficult to assume the hardware is 100% at fault unless you performed the above steps but didnt specifically mention it.

    Yes I reinstalled the OS on the new hard drive. I reinstalled also all my applications from scratch.

    What should I tell them at the genius bar ? What do you think could be the problem ?
