    Hi,
    I have a macbook intel core duo and it shut down in the middle of watching a youtube video. It will not startup freezes at grey screen with apple logo (no spinning disc). There are no abnormal sounds or extreme temperatures. The macbook is just over one year old.

    I have tried the following:
    Ran disk warrior 4 in target disc mode - no problems found
    reintsalled os in target disc mode
    I cannot get into single user mode as it just keeps asking to restart
    I cannot run the os cd in the macbook as it keeps asking to restart

    The only thing I can really do is run the hardware test and no problems are found.
    When I do shift option and choose the cd to startup from, it just asks to restart.

    I have tried resetting the pram and changing the ram.

    When I go into verbose, it tells me there is a kernal panic and something like this ia32_MC1_stats invalid etc

    The restart screen is the multilingial one 'need to restart your computer hold down the power button for several seconds or press restart'

    Can anyone advise?
    Many thanks
    C

    I am having a very similar problem with my iBook. It shut down while I was working and won't boot past the grey screen with Apple and no spinning spokes.

    I was going to just reinstall the OS but I haven't gotten around to it yet as I do not have the discs with me.

    I'd recommend you reset the PRAM (command + option + p + r at startup until you hear the startup chime again) and perhaps the PMU just to be thorough (remove battery, unplug it, hold down the power button for 5 seconds or so). Out of curiosity, what computer did you use to reinstall via target disk? If it was by any chance PPC, you didn't install the right one. Of course, you might just have a logic board problem, but if so, there's not much to do about it.

    Almost sounds like a potential system failure. My grandfather just had this happen to him as an update wiped his entire system folder clean of any data.

    If you are unable to restart on a CD and can see the hard drive in Target Disk Mode, then hardware failure is a virtual certainty. You've really done all you can -- Apple will need to look at this Mac.

    I had this same problem, after trying everything I used my install disks to perform an archive and install, it hasn't had booting problems since.

    Boot from install disks, continue when prompted to install and choose to Archive and Install. It takes awhile, but it's worth it.

    Any type of reinstall (erase/install or archive/install) will fix the problem like many have stated. It's unlikely that it's a hardware failure since you didn't get a pre-boot kernel panic or startup icon - folder w/ question mark.

    Sounds like your hard drive is going bad and the OS is not loading. I had the same problem with my aluminum 24"iMac. I brought it to the Apple store and they repaired it. The hard drive failed on it. Matter of fact it occurred to me three times. The 3rd time Apple gave me a smack brand new iMac.

    The folder/? means that it can't find a system folder to boot from. A vast majority of the time it's a hard drive failure.

    4-5 years is about the average time for a hard drive to last depending on its use.
