fairly old, powering it down and unplugging/replugging every connector a
few times wipes oxide buildup off the contacts and usually solves the
problem.
That was particularly true back in the days of the "model T"
computers - where all of the ICs were socketed - and only the best
used high quality screw machine? sockets. Every memory bit was a
separate chup - with tinned legs.

On today's computers, with gold plated instead of tinned connections,
it is EXTREMELY rare.

I'd say, in order of likelihood- bad power supply (average ATX P/S up
to about 5 years ago only lasted 2 - 3 years) Bad caps on the
motherboard, or bad motherboard. What model board is it???? ASUS,
A-Open, etc and actual model designation???
