Hey guys Having trouble with my GA-z87x-oc where I was swaping out my c drive for another. Pulled out all of the other drives from the system and plugged in new one. System will now not post, shows black screen and throws A6 error code. Took out gpu, one ram stick( swapped both sticks and no change). Even took out new hdd still no post. Swapped out psu- no change Any ideas?
