Hi, I will start the story from the beginning. About a month ago, I had a bad ram stick, GSkill Trident Z RGB. Computer worked fine with it in, but had random crashes about once a week. Sent it back to GSkill and got the replacement pair today. Since then I was using the other 8x2 GB pair that I had. When I went to put the new sticks in, one of them lit u and one didn't, I took out and put back in the one that didn't, still nothing. I swapped the two to see if that would make a difference, then neither of them lit up, but the other two would still light up. I then tried one of the older sticks alone in that slot, nothing. Then I tried the last stick that had always worked in one of the slots that none of the other ram had been in since it was all working, and nothing. Now I have 4 sticks and none of them work in any slot. I have no idea if my motherboard is broken or if the ram is broken. I am worried that if I get a new motherboard, if the ram is frying it, it will break that too, and if I get more ram if the motherboard is broken, it will just fry the ram. And I for sure did not install them backwards or use any excessive force, they all clicked in as they should. Any help would be appreciated, thanks.
