Q: I disconnected my MAC when going on vacation when I went to power it up I got the tone but then a grey screen followed by 3 loud beeps has anyone ever had this happen?

I disconnected my IMac (Intel) when I was away when I reconnected it after the powering up tone I had a grey screen followed by 3 loud beeps and the beeps continued.  Has anyone had this happen to them?   I have tried to reboot in "safe mode" by holding "shift" key down after tone but that did not work.  Any other suggestions?

    3 beeps indicate a RAM problem. This could be:

     

    • Incorrect RAM
    • Failed RAM
    • Unseated RAM

     

     

    Did you upgrade the machine's RAM ?

    My son did I believe when he was visiting and he's not here now. Is this a simple fix?

    Yes.  This Apple document describes how to access the RAM on the various models of iMac: iMac: How to remove or install memory

     

    First step would be to remove and reset firmly the RAM modules and give it another try.  If that fails, remove the new RAM modules and replace with the original Apple modules that came with the Mac. 

     

    The more reliable sources for Mac RAM modules are Crucial.com and otherworldcompution.com.  Both are very reliable and will guarantee your satisfaction. 

     

    Check to see where your son got the modules.  Also check the modules  carefully to make sure they match the specifications for your iMac exactly.
