PC won't post, 2 CPUs tried

[SeeEmAge]

Hello! First I have to say that my English is not the best...

 

My specs:

 

CPU: BEFORE Ryzen 5 1600, NEW Ryzen 7 2700X

Mainboard: MSI X370 GAMING PRO CARBON

GPU: ASUS Strix RTX 2080

RAM: 16GB HyperX

Etc. : Soundcard: SoundBlaster X AE-5

 

First thing. I had the Ryzen 1600 until yesterday. It worked fine but sometimes the LEDs of my Mainboard didn't start to shine and this was the indicator for me, that the PC won't post. After some restarts it starts to work again and then the problem comes back later than 1 month. Since yesterday I have the Ryzen 2700X and it worked really well. I didn't flashed the Bios (It was from April 2018). But since today it makes the same problems like the 1600... But now it done this after every restart and this only 3 times... now it stays in not posting. I changed the 2700X with the 1600 and it posted. So I flashed the Bios to January 2019. I swiped the CPU and it doesn't changed anything. Back to the 1600 It won't post too. I am working on since 4 hours and now I am clueless.

 

Edit: I have to say that I have a water-cooling since today.

 

I hope someone can tell me a tip. :) Thank you!

It is possible you have a failing power supply.

Try reseating everything, including all cables and cards.

 

That's magically worked for me in the past.

That, or(less likely) the motherboard itself is faulty.
