Early IBM PCs and clones are mostly sockets, discrete logic and plain memory chips, which is part of why people repair them. When one will not start, the habit is to read the beep codes, reseat the cards and chips, then check the power supply before blaming the board.
Fault hunting on a 5150 is told in troubleshooting an IBM PC 5150, part one of a series. An intermittent fault on a 386 board is followed in the intermittent motherboard repair, which needs test gear. Four junk boards get powered up in the battery leak video, a way to check boards of unknown history before any repair. Old monitors are covered under crt.
A PC power supply has mains voltage inside and capacitors that stay charged after unplugging. A CRT monitor can implode if the tube is knocked or cracked, so wear eye protection and never lift it by the neck. Its tube and flyback also hold a high voltage charge, and mains runs inside. Leaked battery residue is corrosive.
