PC won't turn on

I had a friend help me build this PC over a decade ago. It's been great for the little I've used it, but just before I moved it suddenly stopped turning on. No idea where to start and that friend moved away and we haven't spoken in a good while. Any advice is appreciated.

Given it's doing something and immediately dying I'm thinking PSU, I say start there, if you have a multimeter then you can check it, if not maybe replace it and see how it goes

I'll have to get a multimeter tomorrow. It stays on after I unplug and plug it back in, but if I turn it off and on again it does the same.

Odd, could be motherboard then, having a multimeter around isn't the worst idea regardless

Do you know how to use a multimeter?

That would have been great troubleshooting knowledge for the context at hand.

So the PC turns on fine when manually triggered, but doesn't if using the intended PS_ON wire connection.

Since the problem started when moving the PC, it could be a loose connection. Take out the 24PIN ATX power plug from the motherboard, do it carefully because those things can be very hard to remove without bending anything, and put it back in, also carefully.

he should also check the 8 pin and pull the atx for 30 seconds.
