Question Monitor not diplaying after installing new RAM sticks

[NonS3nsd]

Hello again. So to kick things of i went to buy new RAM sticks (2x8gb) with the supported MHz rate. Now when I installed them with my other 8gb stick my monitor won’t display HDMI or Displayport. Also EZ DEBUG LED CPU is on. What I’ve tried: All dimma slots with all RAM sticks, CMOS reset, basic power on and off, HDMI cable to CPU port and reinstalled CPU. Nothing mentioned did NOT work. I would appreciate really much if someone had the time to help me!!!
