I'd clean the contacts with some isopropyl alcohol and also check for
cold solder joints on the memory sockets.
You'd have to remove the mainboard though and this can be tricky.
Also physically examine that all the pin legs of the ICs on the RAM
boards are solidly attached to the PCB.
There is the possibility of dead ram boards but that's rare compared to
cold joints,dirty contacts etc
