So yesterday I got one new stick of ram. I put it into my pc and when I went to turn it on, everything seemed normal but I would not get display or power on my usb ports. I moved my old 8gb stick of ram to slot 2 because the new ram would've gotten in the way of the cpu fan. Now when I try to put my original ram into slot 1, it does not work. Only when my ram is plugged into slot 2 will it function. My motherboard is a Prime B360M-K and everything else works fine. I noticed later that the ram had different cas latencies so that might have caused the problem but I can't be sure. Sorry if my writing is horrible, English is not my first language.
