PC wont power on.

[Erlhyenaplays]

So earlier today, i was putting a second GPU in my PC. I did not know at the time, but my PC was on. There is a spark somewhere in the PC, where the GPU touched, and now everything is broken. Nothing turns on, no signals of power. I tried switching out my motherboard, nothing. I did hear a faint buzzing in my psu, though, and replaced it as well. Nothing. I an all out of ideas, can anyone help me.

Parts list: AMD ryzen 5 4500,
enermax liqmax III 120 rgb AIO,
AMD radeon 5700 xt,
former mobo: ASUS ROG strix b550-f gaming wifi II,
new mobo: ASRock x470 sli/ac,
former (prob broken) psu: EVGA SuperNova 550 G2,
new PSU: corsair cx450m

 

The newer parts i replaced the presumably broken parts with have been sitting out for about 6 months, if that is helpful.

Well, you've replaced the motherboard and the PSU without results, so either the PSU and board weren't destroyed or (more likely) there's other stuff beyond them that got destroyed. 

 

 

Next up would be trying with different CPU and GPU (in the "new" board).

The GPU wouldn't be the cause of the PC nt turning on, would it? I could understand that is it didn't show video to the display, but i doubt it would be causing this problem.

We already know you have a second GPU, so there's no reason not to try it to eliminate it as the cause.

ok.

[Middcore]

By the way, I notice both of the original PSU and the alternate one you tried are modular. You did replace all of the modular cables when you swapped, right?

So, a weird thing happened. The beeping sound is back. I should've expected this, but it was prob broken. I did find some signs of it possibly being broken, sugh as it being slightly wettish and stuff. Certainly not expecting that.

I'm kind of confused. The beeping sound is back? I don't see where you ever mentioned a beeping sound before. 

 

You say something is "slightly wettish" but I have no idea what part you're referring to.

so there was a buzzing/beeping sound coming from the PSU before i replaced. The new one has it too. the new one had some ink from a printer on it in various places.

Define 'on'.  Was on on where the CPU and case fans were spinning?  Or was it 'on' by meaning you hit sleep instead of shutdown, or was it 'on' that you did a shutdown through windows and left it plugged in?

 

At this point it doesn't much matter, but you need to understand where you went wrong.  Every manual that comes with a GPU specifically says to 'UNPLUG IT'.  

 

My diagnosis:  It's all e-waste now.  All of it!  Why?  Because you worked on a live circuit.  GPU slots can get up to 75w from the motherboard slot alone and you reverse shorted it through the slot, your motherboard, and out your PSU.  You are very lucky you didn't explode a capacitor in your face or catch your PC and/or room on fire.  You likely also fried the electronics in your case so the power button doesn't work which is why you can't turn it on.

 

My advice is to stop plugging good parts into anything you used 6 months ago and just start completely over.  If you're going to continue to try and build pcs, get a fire extinguisher to.

 

What new psu did you get that has what you call printer ink on it?  It's probably not printer ink, it's probably from a busted cap.  Capacitors contain a conductive liquid called electrolyte.  What in the world is even going on, are you trolling or something?  What PSU is it, was it brand new?  Where did you get it?

 

I haven't seen something this silly in over 30 years, when a customer didn't have an available 16 bit slot available on his motherboard, so he took it out in the garage and filed the pcb down and made a new slot so it would fit in a 32bit pci slot.  Guess what happened, it exploded soon as he hit the power button and nothing on that system ever worked again.  Just wow.

Idk, the liquid was purpleish, and only on the label, and stored in a bag. The GPU works, but ty for your suggestion. Also, I HIGHLY doubt that 'everything' was fried.

New thing: Whenever i turn on and off the power through the swithc on the psu, there is a strange red flash of light on the mobo under a heatspreader

the MOBO in question is the asrock x470 SLI/AC

The strange red flash of light you're seeing might be a busted capacitor shorting or some other form of short. It is NOT SAFE to use this component as the short can generate significant amounts of heat and may even set something on fire. It might even damage any other components that may still work when trying to turn the system on or supplying it with power using the PSU. Please for the love of god DO NOT TRY to use this system if you're not sure what you're doing.

It looks more like a LED light than anything else

I showed some tech-savvy friends the thing, and it flashes blue randomly sometimes. It is not a short.

At this point we have one PSU that is compromised from what you did trying to install the new GPU, and one PSU that is suspect from... something... happening while it was in storage.

 

To figure out anything about what other parts still work to be salvaged, you're going to have to get your hands on a third, known good, PSU for testing.

am planning on getting one for xmas, and will turn my computer in to a computer repair shop. Will update when further info is acquired.
