Inserting IC's into the sockets creates a friction that cleans and almost
scrapes the contacts. It's the only way I know to clean sockets. You've
replaced the RAM and 74xxx series IC's, so I'd try swapping out more, like
the CPU, and anything else you can find. It might not be an IC but a
component like a blown cap, or maybe even a bad solderpoint. Check over all
solder spots with a magnifying glass. Look for cracks in the solder.
