My server won't turn on 🫤 (self.selfhosted)

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!

Edit: I made a new post asking for hardware recommendations.

Edit 2: I managed to get a light on the motherboard, going to buy some more thermal paste and keep tinkering to see if I can get it started!

Edit 3: I never got that light to go again. In the end the comments on the other post convinced me that I had all that I needed for what I wanted (no upgrade needed), so I changed tack to seeing how to fix it. I had suspicions about the power connection still, so I bought a cheap PSU and tested it, no change. Then I bought a new motherboard (also a pretty cheap one, the cheapest that had what I needed and was also in a local store) and in the end that was the issue. Everything is up and running again now! Thanks for all the help everyone, you can now settle your bets.

@Dave is the power supply's internal fan spinning if you power it on without it being connected to a motherboard? Shorting Green (PS_On) and Black (Common)¹? That will help isolate the issue to the power-supply or motherboard?

Thanks for this. There was no green wire but I worked it out based on your link and got the fan spinning, so it seems the PSU is fine.

@Dave the PSU works but still might not be putting out all the right voltages. Unfortunately all further troubleshooting on the PSU and motherboard might need a digital multi meter. Can you get your hands on one?

[–] Dave 2 points 2 years ago (1 children)

I might go buy one today and give it a go. It would suck to buy a new mobo and find out it was the PSU after all 😅

[–] shom@fosstodon.org 2 points 2 years ago (1 children)

@Dave yeah mate, my money is always on the PSU and a multi-meter is always handy to have around. Keep me posted, I'm invested now 😂

[–] Dave 2 points 2 years ago (1 children)

I did it, got a multimeter, followed a youtube video and tested it out. All the voltages are right, coming through fine, so it seems the PSU is fine.

At this point though I'm starting to think I might just use the opportunity for an upgrade. New mobo and CPU, and probably get a buttload of RAM (currently have 16GB DDR4). Will probably do a new post asking for hardware recommendations.

@Dave Ah bummer, at least you know now.
I wouldn't shy away from buying a couple generations older, especially for a home server, loads of good deals to be had on those. Good luck and enjoy your upgrade!

The current stuff is only from 2019. Replacing it like for like is no fun, I want fancier stuff 😆
