Computer crashes are simply where one's body will just go wrong and either restart or freeze. A "crash" can be a term used to spell out whenever a PC is either struggling to process your commands, or comes with an error that causes it to stop running & restart. Although crashes are extremely common, and therefore are the result of a whole selection of different problems, in fact you are able to fix XP crashes very easily if you're able to repair the different conditions that cause them.
