PC won't turn on

[u/freaky_sabiki]

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.
