Hi 2informaticos !
Thank you for your answer. I am just getting back to it today, and actually I can't finish the OS loading. The artefacts comes while booting and seems to freeze the Mac.
I guess that if it's iGPU related it's game over for this board. But is it if it's RAM related, how difficult is the RAM replacement ? It's a 4Go board with only 4 RAM chip, it could worth the try, do you thing ?

If memory test fail, replace the chips.
Be aware, such failure can still be caused by CPU...
