Loud beeping noise on mac

Video of the Day

Some Macs still use removable RAM modules and you can remove them and reseat them. After doing so, you can try to restart the computer again. This error will have to be addressed as soon as possible because a Mac cannot turn on without memory. If you hear 3 successive tones followed by a 5 second pause repeatedly, this is another sign there is a problem with your Mac.

This can happen when the RAM module is not seated properly or a problem with the connection between the RAM and the logic board is present. Ensure that the RAM module is pressed into the slot all the way and that the retaining clips are holding the module tightly in place. The Mac will display a loading screen and take care of itself; you just need to have patience. Have you ever had a strange startup sound when turning your Mac on?

I have a macbook pro 15 inch aluminum unibody that was the latest model when I bought it back in January this year. I have not added any ram or changed the hard drive or added any third party hardware to the computer. I am running Mac OS The computer had been going with with nothing unusual and I was browsing the internet in Safari when suddenly I heard this disturbing beeping coming from my mac.

The sound was quite short and quite loud. It reminded me of the beeps made by macs when you reset the pram. The beeps were quite random. The beeps seemed to become less frequent when I disconnected from airport and more frequent when I reconnected. Eventually I changed user and then left my computer for a time and then changed back to the affected user and the beeps had stopped. The beeps were definitely not my system alert sound as it sounded quite different. Also they didn't respond to changing the system volume, whereas my alert sound did.
