    It might be because the RAM is not inserted all the way into the socket. Check and make sure they modules are firmly pushed into the slot. From the looks of it, seems to be a bad module. Try resetting the PRAM, then try and see what happens.

    Thanks chargerbaseball25, I've tried 3 times, just to make sure they're firmly pushed into the slots, but I still got the same "BEEP".
    How do I reset the PRAM? what's that?

    Thanks again!

    Resetting PRAM and NVRAM is a simple solution that might help your situation.


    1. Shut down the computer.

    2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

    3. Turn on the computer.

    4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.

    6. Release the keys.

    Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.

    Also, you might be interested in what is controlled by the Pram. This is what it controls:


    Status of AppleTalk
    Serial Port Configuration and Port definition
    Alarm clock setting
    Application font
    Serial printer location
    Autokey rate
    Autokey delay
    Speaker volume
    Attention (beep) sound
    Double-click time
    Caret blink time (insertion point rate)
    Mouse scaling (mouse speed)
    Startup disk
    Menu blink count
    Monitor depth
    32-bit addressing
    Virtual memory
    RAM disk
    Disk cache

    I would do it with both, just to be sure.

    This is sort of off topic, but why is any of that aside from startup disk being stored in PRAM and all that? I've never understood that...seems like lots of weird issues with it all the time (well not really ALL the time, but on forums like these).
