Re: Asus x556uj black screen
Did you make a backup first before trying the other bios ? ,if you did then post your bios backup ,also post pictures of the white/green labels on the motherboard, they are usually on or near the RAM slot .Last edited by SMDFlea; 03-27-2021, 07:20 AM.

Re: Asus x556uj black screen
I can't do it, other than cleaning the ME region, I cannot do any repair, I do not have the skills or knowledge or tools. The first three dumps are all different, they shouldn't be, and you really shouldn't have erased until at least two or three dumps are the same. Better yet, if you suspect the chip, get another one, it might be dying on you every time it's read or heated up. Good luck.
