Hi, a few months ago i encountered this issue with my system. I have 4 ram sticks each 8gb so in total 32 gb. For a while they were working fine and the system worked normally. Then one day it just stopped booting, i did my fault searching by stripping it down part by part to figure if any part was faulty. No problems with any of the parts. Then i took the ram sticks out and started with just 1 inserted, then it worked fine, added another one and it worked just fine, added another one and then it wouldn't boot again, so i figured 2 of my ramsticks were faulty, but i did the same procedure with all the ramsticks, inserted into all the different slots, and they all work just fine. Even tried it on different systems and they all work. The problem is inserting more then 2 and the system won't boot. I tried everything and i can't figure out what the issue could be. The ramsticks are Kingston HyperX fury 32gb (4x8) 2666mhz. Anyone have any ideas on what it could be? I also updated the bios on the mobo and it didn't solve anything. The last solution is of course formatting the entire thing, but i have my doubts that it will solve the problem.
