Hi there, I had some problem with my macbook pro a while back, in which the screen was getting blank/frozen and I had to force quit it, and when i tried to turn it back on, it started beeping and would not turn on…then I would wait some hours and it would finally turn on. It was acting like this for a while and I managed to fix it by repairing the disk in disk utility and it was working fine… Now, since yesterday, it started again, and i had to force quit it, but this time, it is not turning on at all anymore, and it only does the beeping sound when I try to turn it on…firts it does one beeping at a time, and then I force quit it again and turn it on again and it does a faster beeping sequence. Can anyone help me? my mac info is: Mac OS X version 10.6.8 2.4 GHz Intel Core 2 Duo 4 GB 1067 Mhz DDR3 I never did any work on it, never changed anything…it is just like I got it from the shop. Thanks

3 successive tones, a 5-second pause, 3 successive tones is the RAM integrity error. As Bernd recommended reseat your memory or replace it. Heres the Apple TN on boot up tones Tone Errors for reference

Hi Tania, how many beeps do you hear? Or is it beeping constantly without an interruption? Sometimes this symptom is caused by the memory. Have a look if it is seated propperly. Good luck

Start up and hold down the on/off button until led will blink rapidly and mac will start up fine.
