Pc won't boot

[Vatsug]

Hi guys i was just wondering if my suspicion is tru but my pc won't boot up and keeps clicking on and off when I press the power button. Im wondering if i need a new psu or if it could be a different problem altogether

I am uploading a video to give some visual insight into what's happening

Did your PSU come with a self test detection tool? Most high end PSU include this, otherwise you can use the paper clip method to test a PSU.

You can google for simple instructions.

dont know if you've tried anything to trouble shoot yet?

 

but remove power cable from psu and also remove 24pin from motherboard, press the pc case power button a few times replug everything in and try.

No i haven't tried anything yet

So try removing the 24 pin as I mentioned, its either the psu protection kicked in and sometimes removng the 24 pin as well as the power cable resloves it.

failing that it could be the psu detecting a short somewhere in the system and thus also protetion kicking in,check all cables are firmly in 24pin, 4/8pin mobo, gpu, drives etc

so if its a short try removing everything not needed to get the system to power on and stay on and try to fnd culprit i.e

 

gpu

ram (just leave 1/2 sticks in try different slots)

drives

remove everything not necessary for the system to power on, fans leds everything

check cpu socket

reset bios

oh and if all that fails rebuild out of the case as could be causing a short somewhere

For now i have it unplugged

[Vatsug]

Welp i got it down to bare bones and it still turns off... uploading a vid now

Found out the screeching is coming from the motherboard

[aledsav1]

ok screeching is never a good thing, usually means some sort of electrical load that is not right.

 

you def have the 2x4 pins in the cpu connector on the motherboard yes? I see a cable going that way...disregard i can see you had it plugged in from first vid, just double check all cables again

 

remove all nvme drives as well, I can see the obvious one in the top slot is there also one behind the lower heatsink?

 

have you also checked the cpu is in correctly no bent pins etc

 

Not sure on the history of these parts?

 

 

[Vatsug]

I reseated all the parts individually and still no dice

[aledsav1]

Well as it stands you only have the option for more trail/testing etc, ideally you have another psu (even though its firing up)/motherboard and chip to cross reference in order to determine where the issue lies, am not sure of that board if it has led display for errror code or just leds indicating where the board is not progressing past, though if its only on for a second or 2 then even thats of no use.

If everything is connected correctly at both the motherboard end and psu end and firmly plugged in and the cpu/socket is intact then my thoughts are the mobo is faulty or still being shorted somehow.

[Vatsug]

Yeah i think its just the motherboard.  I had issues with it before but it was doing fine till recently. It finally kicked the bucket i guess.
