No power to PC?

[Waffle_paradox]

So, around 6-8 months ago, I built a PC, worked great. Just around a week ago the PC stopped functioning. No LED's, no fans, no nothing. I tried replacing my PSU and motherboard, with no success. I'm honestly at a dead end here, can somebody help?

Have you tried testing if the wall socket even has power ? The circuit breaker might have tripped.

Try plugging the PC somewhere else. It's not rare for crappy houses to have many sockets on the same circuit breaker, you use up too many amps on the circuit and poof. The breaker trips and no more power.

Already done that sadly.

and you are 100% sure the socket has power ? You plugged something else in it and it worked fine ?

I have a charger plugged into it, fully functional.

have you tried swapping the wall outlet you're using? there's a chance a breaker was flipped.

Done that already unfortunately

So no power. No lights or fans spin. You already switch to a different psu and motherboard but still did not work. You even tried to use a different wall socket. If it's a gpu or display, it would at least light up. You already switch the psu and motherboard, so it should eliminate that being the issue some what. Have you tried to short the starting pin instead of using the start button? If you are using a avr/ups have you tried if that's working? If anything, have you tried to remove everything from the case and just built it on top of the motherboard box? if your cpu has igpu, you can try to boot it using only 1 stick of ram(try it on all slot available one at a time) and without the dedicated gpu. Try to boot it without anything connected to it first, not even hdd/ssd.

I've tried using both my power button and shorting the pins, no response. I've rebuilt it from out of the case twice. I'll try booting without anything connected once I can.

Just tried booting it without anything, no response. Maybe I'm unlucky and just got shipped a defective motherboard?

At this point, I'd say take the guts of the PC out of the case and try booting it outside on the motherboard box. Either there's a short in the case (extra standoffs do that), or the power button of the case is defective for some reason (which has happened to me before). Use a screwdriver on the front IO power pins to boot up the computer.

 

Do you use a power bar for the computer or is it plugged directly into the wall ? If using a power bar, is it switched on ?

 

I would strongly suggest bringing the PC to an IT tech who could help you diagnose the issue in person.

Forgot to mention it's been out of my case, sorry. And no, i don't use a PowerBar. I was thinking of taking it to an IT so I could get it diagnosed.

As stated, plug the power plug directly into a known good wall socket, no power strip or extension cord. 

On the motherboard, when you power it on, are any of the EZ Debug lights lit (ie) CPU, DRAM, VGA or BOOT? This will tell you what hardware has failed.

If no Debug lights on,

 

Remove all unnecessary hardware to boot the computer (ie) unplug All drives, internal and external.

Remove all but one RAM Stick. Switch the module and the port around.

If the Motherboard has integrated Video, remove the GPU (video card) 

Boot the computer. Do you see the Motherboard Manufactures Logo Splash Screen?

If so, boot into Setup (Bios) 

 

If you still get no lights or fans from the motherboard, it is usually the PSU, even though you swapped it out. Or you haven't plugged all cables from the PSU into the Motherboard.

 

If you can get into the Bios, shut down and add one hardware piece at a time until it fails, then you will know the culprit.
