Corsair vengeance lpx 1x8gb 2400

This was the computer that I had built almost a year back but was unsatisfied with it because it never had enough ram to do multiple tasks at once. I had bought another stick of Corsair vengeance lpx (1x8gb 2400) but when I had installed it into the other ram slot the computer would turn on (leds on motherboard) and fans would start spinning but no picture was displayed (I’ve made sure my monitor works with second pc). I then switched the original stick to see if the slot was the problem and left the new stick out and it booted. Then tried just the new stick and no boot on either slot. I kept switching the rams sticks between slots and reseated my gpu and cpu multiple times (no bent pins on cpu) and got it to work once. It booted like normal with both sticks and was running ok. The computer recognized both sticks but said one was 2133 and the other was 2400 in the bios. In task manager it recognized 16gb of ram but was only using 8gb. I decided to try to switch the ram sticks between slots (to try to get it to use 16gb) which got me back to square one with no boot with two sticks and only the original one working. I’ve updated my bios and that hadn’t changed anything. Any help is appreciated.
