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

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!

Have you tried turning it off and on ag- oh.

In all seriousness, maybe a blown capacitor of any kind? You describe the PC working fine 'before.' When was 'before?'

There is no obvious damage on the motherboard, capacitors look fine.

"Before" was immediately before I turned it off and opened it up to clean out the dust. It was being actively used as a server.
