      Could you also include the power supply specs E.g Cooler Master 850W Gold V2 NOT E.g 850w
      What ram are you using - and speed
      Did you remove the plastic cover on the ram chip
      Did you use thermal paste?
      have you tried without the GPU

          And these two? - Not trying to be funny. This happened just recently.
          Your ram is not compatible with your CPU. However, it should not be the cause.
          Can you try with just 1 stick of ram.

            Put 1 stick of ram into Slot A2
            Have you connected the cpu power to the cpu1 connection.
            Is your cooler connected to the CPU Fan1 or the cpu Pump1

              Looking at Pic 0111 It looks like the cpu power is not connected.
              I cannot be 100% sure because it goes blurry when enlarged.
