MacBook Pro won't start and beep three times sometimes
Hi,
I have a MacBook Pro 15" from 2010. It used to work fine, but all of a sudden when I tried turning it on one day it wouldn't start up and give me three beeps. I knew this could be a RAM issue, so I reseated the RAM, after which it booted fine again. A day later however the problem returned. This time reseating the RAM didn't do the job. I assumed it was faulty RAM so I ordered a new stick of RAM. Once I got it, I replaced the old one, but the MacBook would still beep three times. After several attempts I got it to boot with the new RAM.
Up to this day, it will almost always beep three times and not boot, although sometimes it will boot. I am absolutely clueless, because an issue with the RAM modules seems ruled out. Does any of you have any ideas what the problem might be? Thanks.
