Right till yesterday all the ram slots are full. I can run my super computer 32gb no problem. Today my computer suddenly falter. so yea i went on the troubleshoot routine and found out my computer can only be booted with 1 stick of 4gb ram.
As long as i add more ram, it won't even boot to mobo utility just a black screen.

Thing i tested out
1) In the bottom half of the ram slots, only the very bottom slot (red) will recognize the ram. If any other ram is added in the above three slots, my computer will not boot (not even mobo utility)

2) As long as the very bottom slot have 1 ram and no other slots are filled in the bottom ram area, my computer will boot but no matter how many ram i put in any of the slots above the cpu, it will only say 4gb of ram.

so yea what's the problem lol. Is my ram slot broken? i need to buy a new mobo?
