I have a 24inch Core 2 Duo iMac. Recently it has been making a sporadic beeping noise. It beeps a few times at start up and then at no regular pattern for about an hour. After that the beeping stops. I turned off the speakers and tried using the computer as a different user and the beeping still happens. Has any one had this problem? Suggestions for a solution?

    yes --
    How many beeps at startup?
    This is an important detail:

    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable

    Edit: Read this thread, it may help as well:

    Thanks, that is a good thought. I should of said that is starts beeping after the machine is fully booted and the login screen appears. The machine runs fine and there are no unusual messages in the logs. I have reset the pram and the nvram and also reset the SMC. The beeping still persists. It does beep a bit less after resetting the SMC but, then it slips back into its ways of beeping at the odd time now and then. The beeping stops after it has been warmed up.
