    Unhappy Help - Mac Pro Start up issues
    Recently my Macbook Pros (OS X 10.6.80) sound stopped working and the sound icon disappeared from the top bar. When I press the volume buttons on the keyboard an icon showing a speaker crossed out shows up and there is not output devices show in system preferences.

    So I read about restarting the computer and holding (alt, cmd, r, p) on start up and this seemed to fix the problem. Then when I was using safari the computer crashed and I had to restart this way again.

    When it loaded again it went to a faded blue version of my home screen with no icons so I used a combination of safe boot (shift when starting up) and (alt, cmd, r, p) to get it to work and this also seemed to work for a while.

    Now if I don't use safe boot when turning on the computer it goes to a faded blue screen and wont load at all. But when its running the sound icon is still gone and sound doesn't work and the (alt, cmd, r, p) method no longer works. Videos, gifs and flash runs strangely now and can crash my computer as well.

    I would really appreciate someones help if they have any idea of what's going on and how to fix it!!

    Thanks a lot!

    Do you still have the Snow Leopard (10.6) disc? If so, can you boot from it, loaded Disk Utility and run a repair on your HD to see what it finds..

    You do need that disk to boot from and run Repair Disk. Sounds like your hard drive may be shot. Are you using a Windows keyboard with Alt? On a Mac keyboard it is Command, Option P and R keys all at the same time after the chime and keep held down until after the third chime.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    A lot of times one of the troubleshooting methods is to create a new account to see if there is something in your regular account that has been corrupted, so it's good that you tried that and found the issues to persist. That means that whatever is ailing your machine is more intrinsic than just a configuration file or something..

    Keep this document for future reference: Startup key combinations for Intel-based Macs

    Hold down C while booting the system with the disk inserted and it will start up. Once it loads, go to Utilities->Disk Utility and run a repair to see what it finds..

    Sure sounds like a failing hard drive. What did Repair Disk have to say after you ran that last time? Remember you have to boot from the disc to run this as Ashwin described.

    Also in addition to what Harry asked, what did Disk Utility say about the SMART status of your HD? While it is possible for a hard drive to fail before the SMART status might indicate, however if the SMART status indicates failure, then it's imminent..
