Is this a sign of a dead motherboard?

When i turn on my pc it turns on then shut down immediately.

I tried everything
Removed it from the case
Replace cmos battery
Put in a cardboard
Tried 3 different psu's
Try one ram at a time
Clean up my ram
Remove graphics card

Is my mobo dead? Or the processor is the one dead?

Might be the a lot of things, it might even be a short circuit somewhere.

To get a better diagnostic, connect a PC Speaker (you should have one in your computer case) to the motherboard so during the Power On Self Test you can listen to the error beep code.

Refer to your motherboard manual to check what the error beep code you listen means.

I thought of that too, back when it was inside the case i loosened the mobo screws then when i open it it didnt shut down the problem was it has no display. So i replace/clean the ram, re applied thermal paste but still no boot. Then the next day it happened again shutting down after opening. I loosened the screws again, nothing. I reroute the wires that goes behind it. Nothing, i said f*ck it take everything apart (cause i thought it was a short circuit) i put it in a cardboarf but boom still nothing. 3 different psu 3 set of ram. 2 set of cmos battery but nothing

Ireally suspect its the motherboard because it is 5 yrs old. If the processor is dead why did it shut down even if a applied thermal paste twice.

I tried again today and its even worse now. From 3-5 seconds now it immediately shutsdown. So no beeping

It looks like either the motherboard or the cpu died. However can't say for sure wich one.

Ouch i dont have money right now to buy a cpu. But a used motherboard will be a lot easier and cheaper to acquire. What are the chances its the motherboard?

Thankyou for all of your responses

Thankyou guys for all of your responses it turns out there is a dust in the processor pins i gently brush them off. And my ram have a dirt that eraser cant clean. So use a cutton buds and alcohol to clean that up
