Upgrading memory to 8GB
I have a problem with upgrading RAM memory on my 13" MBP mid 2009.
When I've installed the new memory I turn on my MBP and there I hear a buzzy noise for a two seconds. It just keeps repeating itself over and over again. When I place the old memory back, it works perfectly.
Can anyone tell me what I did wrong and/or how to solve this problem.
Is this a good question?
