Decided to upgrade my RAM from 8GB to 16. I currently have this kit and I purchased this kit . The only difference I saw was the color, yet when I install the new RAM, no HDMI signal is being received on my monitor, my keyboard and Mouse don't power on and I am unable to do anything. I can use either my old kit, or my new one, but not together. When I purchased the kit the only difference I noticed was the color. Any help would be greatly appreciated.
