Immediately after shutting down the machine, remove ram sticks and put them
in a microwave oven for 2 min, if it is 1100watts or higher.(longer if the
rating is lower)
Then hang them on your Christmas Tree.
PS: Hopefully your microwave oven doesn't become inoperative. (Putting a
small glass of water in it helps prevent damage.)
