    mac pro won't power on
    Early gen mac pro won't light on sometimes. Just sits there like it is dead. Seems to happen when it is colder like if I don't keep it running all night and the metal feels cold. Any ideas?

    Bad power supply? Do you have a spare power supply that you can substitute?
