I'm putting together a PC using some spare parts I've worked with before, but I'm encountering a frustrating problem. When I hit the power button, the LEDs flicker, but nothing happens beyond that. I disconnected everything except for one stick of RAM and the CPU, and I've even tried a different GPU. All components were operational when I took them out. The motherboard has been in my case for years and was functioning just fine until last week. I'm using an older Corsair 650W PSU, which I removed from my setup about three years ago. The CPU is a Ryzen 3 3100 that I recently took out of my daughter's PC. I've been unable to find any shorts in the setup. Is it possible for a PSU to fail just from sitting around for three years? I recall using a paper clip to test PSUs back in the day. Any suggestions would be appreciated!

It sounds like the PSU could be the culprit, especially since it's quite old and has been sitting around for a while. Capacitors can go bad over time, particularly if your PSU isn't a high-end model with solid state capacitors.
I did a PSU test, and it powers on with the correct voltage on all rails, but it won't power the motherboard. Seems like that might point towards a short, if I'm not mistaken.
Thanks, I'm leaning towards the PSU too. I originally bought it for my Q6600 build, so it definitely has some years behind it.
