The word “freeze” has been suggested by Docteur Moundir. On the web, it’s a bringer of bad news. If your screen freezes, it means it’s blocked and you are faced with a blue screen, so that you have to "reboot", in other words restart your computer. This could mean that your computer has overheated because it isn’t properly ventilated. You will, in any case, need to review your configuration. The word "freeze" has also come to be commonly used by lovers of online gaming, to mean blocking another player, neutralising him, in other words preventing him from playing for a given length of time. Usually, it’s the administrator of the game who takes the decision to use this method to sanction a player who has been too aggressive, criticising or insulting other players. By immobilising him for several minutes, the administrator hopes to calm him down and bring him back to behaving normally.
