O my motherboard has 4 ram slots and now only 1 of them seems to be working, something only comes up on my monitor if I put one ram stick into the working slot, if i put another ram stick into another of the slots, nothing comes up on the monitor

Putting in one ram stick into any other slot also doesn’t work, nothing comes up on my monitor

Xmp was causing problems for me before this happened, turning it on made my pc freeze and turn off on its own

So are 3 of my motherboards ram slots dead?
