MSI motherboard won't start, blue LED blinking

Hello,
I built a computer two and a half years ago, and it was working very well until now.
It turned off while I was using it, and since then I haven't been able to restart it.
Nothing happens, no fans or debug LEDs (red LEDs next to the RAM for CPU / DRAM / VGA).

I tried unplugging everything (graphics card and all cables except for the motherboard and CPU power supply).
I also tried a CMOS reset
And nothing changes.
However, when I hold down the power button, after a few seconds, a blue LED starts flashing. I can't figure out what this LED corresponds to on my motherboard (MSI Z170-A Pro). https://youtu.be/OUdACMzI3Jg
It flashes alternating between two sequences:
- 1 Medium, 8 short, 3 long
- 1 Medium, 8 short, 4 long
Each sequence is spaced about ten seconds apart...

Does anyone have any idea what this is and where I could find more information?
I don't want to admit that the motherboard is dead...

Thanks in advance
Configuration: Android / Chrome 73.0.3683.90

    MSI Z170-A Pro = according to the images, the capacitors are not underneath a casing
    I see at least twenty of them

      Hi, thanks for your reply.
      So for the backstory: at first I thought it was the power supply. I took it apart to test it outside, but I blew it up (literally). I must have made a mistake.
      So I bought a new one. It doesn't work with the new one either...

      Hi,
      You can try removing and reinserting the RAM sticks (even though honestly there's very little chance that's the issue, since it was a sudden shutdown).

      On your motherboard, do you see any capacitors that look faulty?

    blown connectors; especially around the processor

    they have bulging bottoms

      Hi, I can't find any, all the capacitors are in a metal case I don't know if it's possible to tell when they are dead.
