When it starts up a Mac runs tests to check the hardware. It beeps to indicate where a problem may occur. 3 beeps indicates a problem with the memory. It is usually advisable to have an Apple service shop have a look at any Mac that is beeping at startup.

∙ 11y agoIf it's an iMac, you need new RAM or the RAM needs to be taken out and put back in.
If its a Windows PC (any kind XP, 7 etc.) the RAM needs to be replaced immediately.
The 3 beeps of your iMac is meaning "No good RAM banks", then a Vacuum Cleaner like noise turns on. Here is how to fix this problem:
Step 1. ~ Loosen the 3 screws where the speaker isStep 2. ~ Locate the 2 RAM chips on the side of the mac.Step 3. ~ Take out the RAM and put it back in.(put back in CAREFULLY!)Step 4. ~ Put the casing back on and re-tighten the 3 screws where the speaker is.Step 5. ~ After when you did these steps, your iMac MODEL SHOULD be up and running with the iMac introduction noise.Step 6. ~ You're done!
Hope this information helps you!
