    Press the power button and immediately press and hold the C key until the apple logo appears and activity happens then release and follow the onscreen instructions.

    The question mark on your screen shows that your operating system needs to be re-installed. Did you happen to have time machine backups setup?

    How did you go about downgrading to 10.5 ? That might explain the problem.

    Has your combo/SuperDrive been acting up at all? Are they factory disks or copies? Also are they device specific re-install disks because a MacBook pro 10.6 disk won't work on a MacBook.

    Im simply refering to the type of cd/DVD drive in your system since i don't know your exact specs or age of your MacBook so ignore that part. Has your drive been acting flakey on you lately? Also are the disks gray? If so those are factory reformatting disk which are usually machine specific so for example a 10.6 disk for a macbook pro would not work in your "MacBook." Or this 10.5 disk could also not be for a "MacBook."

    Nevertheless, pop out the 10.5 disk and let's try and isolate the issue. Since you have supposedly used the 10.6 disk pop that in and try and boot from it and install snow leopard. If successful you know it is something wrong with your 10.5 disk and to scrap your project of trying to downgrade until you get a functional disk.
