    Oy. Its doing weird crap. Again. :(

    Sometimes it will boot perfectly.

    Other times, it will boot, then 10 seconds later turn off. X.X

    And I'm also getting the 3 beeps. Not the 3 beeps again. I hate the 3 beeps. :(

    The power-on self-test resides in the ROM of the computer. Only computers that are based on the ROM-in-RAM (New World) technology, such as the iMac, Power Macintosh G3 (Blue and White), Power Mac G4 (PCI Graphics), PowerBook (FireWire) and PowerBook G3 Series (Bronze keyboard) will generate these beeps. This test runs whenever the computer is powered on after being fully shut down (the power-on self-test does not run if the computer is only restarted).

    If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you should call your Apple-authorized service provider for additional troubleshooting assistance.

    1 beep = No RAM installed/detected
    2 beeps = Incompatible RAM type installed (for example, EDO)
    3 beeps = No RAM banks passed memory testing
    4 beeps = Bad checksum for the remainder of the boot ROM
    5 beeps = Bad checksum for the ROM boot block


    So, does that mean the slots are dead? X.X

    Insufficient power, bad RAM, or too many components and not enough energy (e.g. Insufficient power). I'd say bad RAM. Try taking one out (repeat till you see what does and doesn't work), and seeing if it'll start up.

    I've tried 16 different sticks of PC100 in all the slots so far... >.> Still nothing. I'll try unplugging the hard disks and see if it stops beeping.

    Your board may be fried. Take out everything in the PCI slots and see if that works.
