Mobo probably dead? Need help

[AgentKneegrow]

so story is

I was just browsing / organizing some important things, then it crashed, no warning. (No bsod, no black screen, just instant crash/shutdown)

After that, i tried turning it on again but it wont boot. No LEDs, no fans, nothing.

Some things to note:
- i shutted down my computer and windows updated it , but it turned on by itself even though i pressed shutdown and update (before the crash happened)

- i already cleaned by computer 2 weeks before, already tried plugging all the power connecters and cables properly again.

i'm guessing it was the psu so i iwent and checked.

then i did the paperclip trick, and it powered on the fans. so i thought, maybe i have a faulty power button, but i shorted out the pins for the power switch but nothing, no bootup.

(i already tried cmos, nothing still.)

so do i have a dead mobo?

Any beep codes at start up? Have you tried clearing the CMOS?

it does not even start as i press the power button, so no beeps at all, nothing.

i did the reset cmos on my mobo (shorting it out) nothing either

what else to do?
