    Hi all,
    Every few hours I notice a strange siren type noise, its is fairly low volume and it doesnt come from the speakers. The noise kinda sounds like a police siren and goes on for about 2-5 seconds. It is running OS X 10.3.9. I am just curious what this noise is and what it means.

    There are also some other strange things going on with my powermac, such as:
    It takes a long time for the video card to send a video signal to the monitor while starting up, the screen is black until the login screen shows up.
    There is also no startup chime.

    May I ask how you arrived to that conclusion? Also is it the ram or the ram slot?

    Also this noise only happens every few hours. It isnt constant.

    Try running your computer with 1 ram stick at a time. That should help pin-point the ram stick.

    Thing is in system profiler the right amount of ram shows up and the siren only happens every few hours so it would take a while to figure it out.
