Today, my new ram arrived and I really wanted to install it. I turned off my PC, took out the power cable, opened the PC, loosened the 2x4GB of ram, took them out, put in the new 2x8GB ram, tightened it, put on my PC, plugged it in... And my monitors turned on, yet they had no signal. Also, my keyboard is also off? I experimented by either putting in my old ram or just using one slot of ram, yet it is always the same ending. Might I have damaged my motherboard or ram slots or what can I do to fix it? Please ask any question that may help
