RAM-Problem after installing CPU cooler on new mainboard

[Dragalos]

I recently bought a new mainboard after my old one stopped working. When I got it I installed the CPU, RAM, a buzzer and plugged in the PSU to check if its working or not. It started and I didnt hear any beeps.
After that I started to build together the PC. When i installed the CPU cooler I had problems with tightening the screws for the backplate and I had a feeling that they were too loose. I didnt care that much about it because I first wanted to check if everything is working.
I tried to start the PC and everything worked fine. I started up a stress test to see if the temperatures are higher than normal and it turned out they are. I thought that I need to tighten the CPU Cooler more so I did it. After that the following error appeared when I tried to start the PC: "The following Channel memory did not pass CPU memory test.
Please remove the memory then plug again.
Channel B"

This was fixed when I took out the memory in B slot, but I didnt want to just use 8GB of RAM when I had 16GB so I looked in the internet and found out it might have been the CPU cooler that is too tight. I uninstalled the CPU cooler and reinstalled it again. But then nothing happened when I tried to start the PC. Just a black screen and a few beeps(4short beeps and the onboard DeBug LED showed 55 which indicates memory error) before restarting and doing the same sounds.

I dont know what to do.

Mainboard: ASRock Z87 Extreme4
CPU: I7-4790k
RAM: 2x8GB HyperX Savage 2400MHz
GPU: ASUS STRIX GTX 970
CPU Cooler: CoolerMaster Hyper 412S
PSU: XFX TS Series 750W

Thanks in advance for any answers/ideas to fix this problem.

Try removing the CPU and posting here a picture of the CPU socket.

Can the pins get bent when I tighten the CPU cooler screws? Because the PC worked already but after tightening the screws it stopped working.

They can, if screws not uniformly tightened.

To me it doesnt look like there are any bent pins.
Tell me if you need more pictures.

I would remove and carefully examine the back plate area (post a pic if you can) on the mobo.
Then clean and carefully re-install the back plate and then mount the the cpu and cooler.

They look ok. Try reinstalling the CPU , the cooler and test again.

I have noticed some weird white dots to the left of the backplate(seen in first and second picture). Could this be the problem and if it is how do I fix it?.

I did that already I even tried using the stock Intel cooler and it didn't work either.

Then I'd RMA both board and CPU.

For now I will only RMA the board as I dont think that the CPU is damaged.
I will update you when I have more info.
Thanks for your help so far.

No problem.

No problem.

I think I found the problem. One of the insulations on the mounting screws for my CPU cooler was missing and probably shorted the MB when I tightened them.
Now I have to wait until the screws arrive from CoolerMaster :/.
