Fuzz said:The system board on a computer is full of solder points. Given that, when a solder point is heated up and cooled down over and over again (such as turning on and off the computer) the solder becomes brittle and has more of a chance of breaking.
How about water from -4C to 0C?Ok, what does stuff do when it gets hot? It expands. What does stuff do when it gets cold? It contracts.
