Aurora R8, memory change, no boot up?

So after 2 Years of using my alienware aurora R8 with factory ram of 8Gb, I Decided to upgrade to 16GB

I bought some Corsair Vengeance LPX DDR4 3200 mhz 16Gb ram (2 Modules) And after installation, my pc didnt show any signs of software running. My screen (which was working) was full on black. Even after removing them, and re-installing the factory made 8GB ram sticks, i have been waiting for 10 minutes for any sort of response. I can hear the Liquid cooling and fans running, but as I said, no response. Any advice would help tons
