    Hmmmm, sounds like the ram, possible other hardware. hardrive etc.

    one question, why would you buy it with bad ram:confused:

    Is it the network globe with a folder? I thought that was for netbooting... Could be just not enough RAM to boot. What operating system are you using? See if single user mode will work, see where verbose mode stops loading (or if it will get that far).

    Single user boot- Hold down command-S
    [caution, CLI!!! type 'exit' if you haven't changed much and see if you get the same icons, or just 'reboot'.]

    Verbose logging- cmd-V

    Zap the pram- cmd-option-p-r


    If you never get any further, try taking out ram. It also sounds like the computer is trying to netboot (which is particularly picky about ram) so bypass this with by selecting a different volume.

    Switch startup disk: After booting it up, go to System Preferences, click on Startup Disk, and then select the Mac OSX 10.4.6, on Macintosh HD . The next time you start up you shouldn't get the globe folder flashing.

    Mmm, wait, I don't quite get it. If that 512 RAM stick is bad, you should really remove it right now. If it's bad, it will certainly contribute to instability in your system....
