Q: macbook restart 3 bleeps

I have a Macbook Pro Mid 2012.

 

Sometimes my Macbook crashes sometimes after showing some blue horizontal boxes on the screen. Restarting is not always possible and the macbook gives 3 bleeps.

I removed both RAM memory parts and installed 1 brand new one carefully and cleaned the macbook from dust.

 

Apple hardware test says everything is OK.

 

However; I still got the problem. Anybody can help? I don't know what to do anymore.

MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.4)
