Macbook Pro 13" A1278 820-2936-B three beeps

Hi,

When i turn on the Macbook, it sounds 3 quick beeps each 3 seconds.
I've already swapped memories each slot; tested with new memories; checked screws on slot; checked pads soldered on Logic Board and still the same problem.

I read it also could be faulty Bios, or faulty graphic memorie? Am i right?


What else can i check?

Hi,

Still the same problem, 3 beeps, no boot no image.

Tried reset SMC and PRAM.
