My server won't turn on 🫤 (lemmy.nz)

I decided to clean out my CPU fan as it was clogged, when I assembled everything again it won't turn on 🙁

It's an old desktop PC. There are no lights glowing on the motherboard at all, though there is none specifically labelled "power". Just CPU, RAM, BOOT. None of these light up, not even a flash when it starts.

I have reseated the RAM, CPU, power cables. Removed the GPU to check.

The cord leading in to the PSU works but I don't have a way to test the PSU itself or the out cables, but I have reseated them at each end.

This PC was working fine before. But with no lights on the motherboard I suspect either the mobo or PSU?

Mobo is asrock x570 PSU is silverstone 650w strider gold S series

Any help appreciated!

It's dangerous and you can blew it if you don't know what are you doing but by shorting two specific pins, it's possible to turn on the PSU and see it it's working or not

Did you use a vacuum on the fans and let them spin during the clean?

Not on the PSU fans, and was using canned air cleaning stuff.

Someone else posted a link about testing the PSU. I'll consider it.

When you tear down next, look for missing board components or any that lean at an angle they're not supposed to. Canned air has been known to shear poorly-attached caps or whathaveyou clean off the board. Or maybe one of the wires in the 12v cable is broken and it's delivering power just to most pins... The paperclip test just tells you if the PSU is dead dead, are you able to test with a multimeter instead?

Buzzing while the power supply is off makes me wonder if there's literal bugs in it, if it's buzzing while it's unplugged. I suppose the buzzing could also be remaining power discharging, if it happens just after it's been unplugged.

Honestly the canned air I have doesn't blow that hard, it struggled taking the dust off I doubt it could damage anything. I have had a look over the board and there's no obvious damage.

I'm thinking today's plan might be to buy a multimeter.

The buzzing is immediately after being switched off, so you could be right, could be power discharging.
