    Hi -- I also have a 24" c2d iMac, but the Early 2008 2.8 GHz model, and was until very recently running 10.6 also.

    I somewhat remember the two shades of blue screens. My impression was that they showed up late in the boot-up process. In any case, my first action would be to find the original Apple OS X DVD that you got with your machine (probably it's 10.5 Leopard). Try to boot with that -- does it work?

    If so, there should be a way to run the Apple Hardware Test (AHT) program from that boot DVD.

    A re-install of OS X or a restore from your backups could fix the problem, or there might be a hardware problem with the HDD, for example.

    Hope something turns up. I've been really happy with my trusty old iMac!

    No start?

    before you do anything radical
    1) shut it down.
    2) unplug the power cord
    3) unplug all usb cables.
    4) go have a cup of coffee
    5) come back, plug back everything you unpluged
    6) hit the start button and wait....just may start up

    try powering on the machine and holding the shift key, it will show a progress bar and take a few moments. try that. could need an OS re-install.

    Try to boot in safe mod (shift key), or try to boot in Recovery mod and check your HDD for errors.
