So I'm building a pc that's basically like my existing pc for my friend and it won't post. The led light on the motherboard won't go farther than the yellow ram light. I'm not getting anything on my monitor. I've tried different ram and a different motherboard just to have the same issue. I've tried only using 1 stick of ram in eack slot and every configuration you can think of with the ram slots. I don't understand why I'm havothe same issue with 2 different motherboards and 2 different ram packs.
