blown capacitor motherboard safe to use?

[beginner191]

Hello recently I brought a z97m gaming motherboard, to replace my older motherboard so i build my own pc, my system could not start up(boot half a second and turns off again problem), so I sent my whole pc to the pc technician, at first it was fine, he checking for my motherboard, then he switch a new psu to test out my computer, suddenly, my motherboard capacitor (probably) blown and there was smoke, the technician asked me to come back the next day as he too busy building rig for other customer too. Okay so I came back tomorrow, Everything works fine, my computer can start now with or without gpu. Now the question, is it safe to start up computer with a capacitor blown? Because I would risk damaging my cpu,gpu and ram etc if something goes wrong. and also is it covered under warranty? Sorry for the long story, no spacing and bad english I typed this from my mobile phone.

It's not going to filter ripple, which will cause extra stress on components as well as instability. It sounds like your technician was negligent. I would tell his boss to buy you a new board and to find a certified electronics technician instead of hiring schucks off the street that damage customer's goods.

Oh he caused the motherboard blow capictor - not good - he should have tested psu.

Under wear and tear capacitors do have a time before failure where they will no longer hold a charge or require more power or leak power. It might be good time start looking at new board / system for the future.

Yeah I'm agreeing with professor. Sounds like he didnt have power supply tester and your board was Guinea pig. Which is totally not cool at all and totally uncalled for.

Usually PSU outputs standard voltages. It doesn't matter weather it's 150W or 1200W psu. It might be a manufacturing defect. Most boards comes with 1-3 years warranty. Using damaged board will cause harm in future. Just Have a replacement, it's new motherboard and it's under warranty. Ask the seller for replacement.

1) We don't know what capacitor even blew. It may be one that isn't used right now but may be needed under heavier load or with a different peripheral attached.

2) Is it SAFE?
Again, I can't answer that since I don't know which capacitor blew. It could cause problems, it might not.

Since HE blew the capacitor he should really be replacing the motherboard (or PSU) for free, or it should be returned under RMA depending on what the rules are for the shop and product Warranty but I personally would NOT keep it.

sounds like this "technician" is an idiot and is trying to rake money from you. If a capacitor is blown, you will visually see it. If it is smoke, its likely an IC blown not a capacitor. Your initial symptom could be psu or motherboard related so its hard to know. If your motherboard has warranty and something is visually blown, send it back under warranty.

Thanks for replying all of you, I going to send the motherboard back to manufacturer and see what I can do, hopefully they give me a new one or I have to pay another 150 dollars to buy a new motherboard, missing screws is fine right?

Actually it just the capacitor or ic blown around the audio boost feature on the motherboard, but still the motherboard is safe to use right? I can still start up the computer, but I could risk destroying my other hardware, if my motherboard goes wrong. I better rma it

It's never safe to power (any kind of) damaged electronics. The damage may be increased and destroy other circuits in case of power surge. The good thing is your board still runs but it's damaged somewhere inside. Every single component in the board has some purpose whether regulating current or voltage that chips require or controlling power fluctuations.
You may not be using hardware part at the moment but for making it future proof it's recommended to replace damaged part or board.
I'd personally wait till new board comes and wont power on damaged board to make the situation worse.

RMA it. had an issue with this printer once (printer engineer is my trade), blew a board. Left it on overnight to replace the blown board the following day (this type printer needs to be powered 24/7 as its a high volume inkjet and requires to spit ink periodically). The next morning it had an error, another board had blown due to the one that was the original fault. So yes one blown part can spread like the plague.
