Why is my imac making an intermittent dinging noise?

Yesterday, my imac started making an intermittent 'ding' noice, like someone hitting a bell.
Can anyone tell me what this is please?

Open Console in Utilities & see if there are any clues or repeating messages when this happens.

  • Why is my iMac making a soft beeping noise?

    My iMac is making a soft beeping noise. There is nothing visibly wrong, I just dont know why its beeping. Please help...

    Beeps on startup:
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images.
    5 beeps = processor is not usable

    Hi Joann123
    That sure sounds like the Hard Drive accessing data, some are noisier than others.
    For example: the original 160GB Seagate Barracuda that came in my Early 2006 Core Duo sounded about the same. After using it in the iMac for 3 years I took it out and put it into an External drive, another year later it still sounds the same but works just fine as an extra backup drive for my music and photos.
    I don't think that it is going to fail tomorrow, but if it really bothers you that much backup to be safe and by all means contact Apple as explained by those that have replied in your other thread.

  • Why is my computer making a high-pitched noise?

    It sounds like a plane taking off. It is not the case...

    Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
    Runawy applications can shorten battery runtime,affect performances and
    increase heat and fan activity
    Activity monitor

    If these tips do not help, contact Apple.
    Best.

  • Why is my iMac's CPU fan making a lot of noise?

    Hello!
    My 27" iMac (late 2009) is making a lot of noise for the last few months. The noise doesnt occur when you start up, but after you do something what is not really intensive for the computer suddenly the CPU fan is going up to about 4000 rpm. I have tried resseting the PRAM and the SMC but it won't help. I have inserted an image so you can take a look for yourself!
    Kind regards,
    Emiel

    Try resetting the iMac SMC and PRAM reset again, this time do each reset 2x. On occasion the first time does not work, but if it continues to be noisy then you probably have a mechanical problem and the fan may need replacing.

  • Why doesn't IMac repeatedly burn a cd until it's filled?

    5-6 years ago, I had a Performa and I bought a LaCie external cd burner with Lite Toast. Using that, I could repeatedly burn to a disc until it was full. Last year I got an IMac G5, and I go to burn a cd a second time and it won't do it and I'm told that the cd and dvd will only burn once. 5 years of technology and we go back in time rather than making giant strides.??? Why doesn't IMac have the ability to repeat burning? I attempted this answer sometime ago and was told about Burn it Again Sam, and I bought it, but it didn't work right off and I haven't had time to pursue it. I just bought Roxio Titanium Toast 7, and it won't burn again either on the IMac.....that I know of; I just tried it once. It seems like Apple should fix this or offer a solution. When you buy something new 5 years later (IMac) then you should be able to do better things than you could do with an external burner 5 years before.

    You must use the 'write session' option to leave a CD "open" for more burns later. If the first burn closes the disk (with a 'write disk' option), you will not be able to add data later, regardless of the burning software you use.
    Since you have Toast 7, I suggest you review its manual or help topics for more information on what CD formats support session writing & using its preferences to change recorder settings from disk to session for them.

  • Why does my iMac display go off when I am starting up or waking up my machine from sleep..

    Why does my iMac display go off when I am starting up or waking up my machine from sleep..?
    When my iMac goes to sleep I then later try to click the magic track pad or keyboard and it will usually then show the initial password entry login screen and then go off. The machine is still on but the display is black and will sometimes flash up the screen again if I press the magic track pad or keyboard but will then black out again..

    Well, there are many different reasons why it does this. It might shut off due to power voltage problems, system overheats, or there is a System Problem. The reason it might be hard to boot up is because your power button might not work properly or your system hard drive is damaged.

  • Why is my imac so slow browsing

    why is my imac so unbelievably slow.I have a gig of ram?

    "I have a gig of ram?"
    What are the other specs? Processor speed? Free space on hard drive?
    Is the slowness limititd to some sites?
    Slow choppy web video is the most common complaint, and there is not much you can do about that. The newer video technology is optimized for Intel processors. That aren't many G4 friendly vidoe web sites around any more.

  • Why will my Imac (1 yr old) only print the full document in half a page?

    Why will my IMAC only print the full document in half a page? All updated IOS downloads.  My Laptop Mac does not do this, so I feel it is not the printer, but the actual computer.  The full document is printed, it is just half a page, other half is blank.  This is presenting a huge problem for school and also when I need to print a shipping label ( which I do often) for my business.  I have several printers and it performs the mistake on all of them.  Thank you!

    Make sure the scale in the Print window is set to 100%

  • Why does my iMac only have 1 GB of memory?  I hardly have anything on here.  I cannot download software update in order to get Turbo Tax to work.

    Why does my iMac only have 1 GB of memory?  

    Put in more RAM. Visit OWC, DataMem, or Crucial.com to purchase memory for your model. You computer would have more memory had you put more in a long time ago.

  • Why does my iMac appear many times in my network and labelled 1,2,3, etc

    why does my iMac appear many times in my network and labelled 1,2,3, etc

    Ok, I solved it.
    I followed this steps:
    1- Turn Off Wi-Fi from the Wireless menu item
    2- From the OS X Finder, hit Command+Shift+G and enter the following path:
    /Library/Preferences/SystemConfiguration/
    3- Within this folder locate and select the following files:
    com.apple.airport.preferences.plist
    
com.apple.network.identification.plist
    com.apple.wifi.message-tracer.plist

    NetworkInterfaces.plist

    preferences.plist
    4- Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if needed.
    5- Reboot the Mac
    6- Turn ON WI-Fi from the wireless network menu again
