Re: Not IT, but a similar experience
Not sure about oxidation - I thought it used to be that RAM modules in the "black plastic rectangle with silver legs all along the long edge" type, chips basically, were heated while the PC was in use and cooled when it was turned off, and basically slowly wriggled out of their sockets. A carefully placed thumb press on the centre of each black bit, not touching the legs, fixed that.
Later: a laptop's own UEFI memory test was apparently fooled by its memory cache or something, passed. Booted with SystemRescueCD (Linux) and that memory test said, yup, a dead module. That was DDR-something.
