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!

    I’ve tried just directly shorting the power switch on the mobo to rule out issues with the case switch, but that didn’t help.

      Well, reading this and the rest of this thread, I can’t think of anything else. Since you ruled out pretty much everything else, I would now put my money on one of the parts shorted during cleaning… anecdotally I’ve heard parts dying by shorting them with your fingers, but it never happened to me, so that would be pretty unlucky.

      Last time I did a cleaning of a particularly dusty system, a dustbunny flew in the PCI-e port without us noticing (it was dark and circumstances were not ideal). With the GPU Re-inserted, that was enough for the system to behave similarly to yours, but you re-seated everything so… That would eliminate this as a possibility.

      You could share a photo of the current situation, a top down of the mobo? Eliminate chances you are missing something by secondary means(as opposed to just text)?

        Sure thing, here’s a photo:

        top down photo of motherboard

        It’s sitting inside the case but not installed, no cables connected, Edit: RAM is out. RAM is right there in the photo 😅 . I left CPU in because I don’t want to have to do that one yet again 😆

        This photo makes it look quite dusty haha, but this is after cleaning!
