    I'm expecting madjew to come in here soon with the responses;

    reset your PMU
    reset your PRAM


    However, if you want my advice.. hug it. Or try and boot from the CD and see what happens.

    Try booting in single-user mode and running FSCK.

    Choose Disk Utility from the Utilities menu.

    However, you don't need to use the DVD. Just boot from the hard drive and hold Cmd-S at the tone, and it'll drop you into a shell. It'll even tell you how to run fsck :)

    Definitely run fsck, as iGary and Nermal said.

    If that doesn't work, it might be quicker simply doing an Archive & Install from your OSX disks. :)

    You can also try:
    On startup hold Option+Apple+O+F
    Boot into Open Firmware
    At the prompt type
    Code:
    reset-nvram
    Press return
    At the prompt type
    Code:
    reset-all
    Press return
    The mac will boot up.

    Lemme know if that works!

    Thanks E1 for the information on this simple problem for the Mac ol' guys but i'm still a n00b @ some Mac problems ..

    So in a week i'll be doing the troubleshoot steps then .. :eek: :eek:

    So i get some cash for a simple job, i might be working on the iMac FP and another XP box :eek:

    My cousin's house has 2 Macs/Xp box in the same room :eek:
    so it's easy to work on all the systems ..
