    I ran software update which gave me an error and asked me to restart. I hit "ok" and when the computer tries to boot, it gets to the load screen which in addition to the normal "spinner" now has a loading progress bar. Every time it gets roughly 25% through the progress bar and then simply shuts off.

    I tried zapping the PRAM and have tried starting into safe mode but neither work.

    HELP :confused:
