Hi and welcomed to JustAnswer.com.

My name isXXXXX will assist you with your issues.

When did you have this problem?

Please remove the Power cable from your iMac. Press and hold Power button for 30 seconds. Connect Power back to iMac. Turn it on. Does it turn on or still have the same issue?
Customer: replied 3 years ago.

Still have the same issue.

Expert:  Nick H. replied 3 years ago.
Thanks for your reply.

The beeps indicate memory issues. You can do PRAM reset as follow:

  1. Remove Power cable and press Power button for 20 seconds.
  2. Connect Power cable.
  3. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  4. Turn on the computer.
  5. Press and hold the Command-Option-P-R keys.
  6. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  7. Release the keys.

 

If does not work, we will have to remove and test Memory sticks. Do you familiar with electronics? I will show you how to remove and reseat Memory.

Ok, lets do it.

Expert:  Nick H. replied 3 years ago.
Sure. Please CLICK HERE to see the instructions and photos. What we need is to remove all memory sticks out. Test one memory stick at a time to see if any or both faulted.

Let's say your iMac has 2 sticks A and B. Test stick A first then test stick B. We should find out which memory faulted this way.
Customer: replied 3 years ago.

I tried all memories individually... same thing. I even swithed them around, but no luck. I also tried a couple of memories I have laying around. Are you certain that my symptoms is a momery issue?

Expert:  Nick H. replied 3 years ago.
I am very sure that is the case. I have seen this issue many times. CLICK HERE to see the beep patterns. Look for number 3.

If you have time, you can bring your iMac to a local Mac repair shop or Apple Store to have it checked. For appointment to your local Apple Store, CLICK HERE.
