    I have a MacBook Pro 2.33 GHz Intel Core 2 Duo, running Tiger 10.4.11. It has an issue where it takes a LOT of tries (10 - 20 tries) to get it to start up. When I hit the power button, it will turn on, the hard drive spins, the fans go, the usb ports work (I had a laptop cooler hooked up to it that would spin when I turned the computer power on), BUT the screen stays black, no chime. If I keep trying, by holding the power button down for 10 seconds and then hitting it again, it will usually start up on the 10th or 15th or so try.

    I've tried varying amounts of time between tries, five minutes, ten minutes, overnight, etc. I haven't done any recent software or hardware updates. Once the computer starts up, it works just fine, aside from running quite hot (typically 60+ sometimes up to 80+C when I'm running photoshop or illustrator).

    I've also tried taking out the battery and unplugging everything from the computer before I try starting it again, no luck.

    Any thoughts?
