My MacBook Pro 5,3 mid 2009 has been to the Apple Store about 3 times. Each time the problem comes back. See attached screen shot. The problem is that the screen image totally fragments.
My 1st motherboard never gave me any trouble, even with 3rd party RAM - but it had to be replaced because the SD card slot was tight.
Ever since the replacement, the resulting problem cannot be solved. First, Apple suspected it was the motherboard which has been replaced twice. Then Apple suspected it was the graphics card or LCD monitor, which were also replaced.
I tested the RAM using the Rember testing software, and that indicated the 3rd party RAM was ok. Note that this same RAM never gave problems with my original motherboard.
Initially, Apple thought it could be software-based, but the problem persisted even with a clean install.
Any ideas?
