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!

    Did you use compressed air to clean out the fans?

    It’s possible to fry circuitry if you artificially rotate the fans too fast, as this generates an electric field more powerful than the fans and their attached components are rated for.

    Probably rare to cause damage with modern computers but an old PC might be more susceptible to this type of damage.

      Not compressed air from an air compressor, just the canned stuff. I don’t think I spun any fans too fast. Plus the PC is only 5 years old.

      I joked the dust was what was keeping the PC running when this happened to me. But your explanation makes more sense. Dang
