    I just installed New RAM that i bought on Newegg. It said it was the right kind of RAM for my PM G5 dual 1.8

    Installed it and got the three blinking light thing. Which i guess means bad RAM.
    Took it out, and put my old (working one minute ago RAM) back in....still getting the 3 blinking lights.

    Uh Oh..

    suggestions?

    Got a backup of that drive? If so, I'd try booting from your install DVDs.

    Good question.
    If you can't boot from it then I wonder if it's your ram slots. Maybe somehow they were blown? Did you check on maybe macsales.com to see if the ram they recommend is what newegg.com recommended? A few weeks ago I noticed newegg.com was not stocking much Apple related stuff. Another user pointed it out here as well. They never had a reason but I wonder if you got ram not intended for a Mac. Did you try to reset the PRAM?

    Oy


    what did i do??!

    This thing was fine ten min ago...

    Now it just goes to a double blinking light.


    Looks like a hardware problem.


    How do I reset the Pram again?

    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    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.

    thanks


    but, tried that. No dice. I'm not able to get to the grey screen.

    It just blinks twice...the power button that is...black screen


    jeez...this sucks

    You are installing the memory in PAIRS.... right? :D

    Disconnect your power cord. Press and hold the Powerbutton for 10 seconds. Leave it sit for an hour or so and plug it all back in and then try to boot it up again.

    Hopefully you grounded yourself before going into your Mac? You could have had some static discharge and blown a few vital circuits. You could also try to reseat the memory and wipe the contacts first.

    Does your dual 1.8 have 4 memory slots or 8?
