Keyboard problem

The essence of the problem is that recently, sometimes the keyboard (or the system itself?) Freezes for a few seconds, and then immediately displays the characters that were entered from the keyboard during this freeze. The same happens in games, when you move with WASD, it also freezes, and then the character moves on the same keys that were pressed during the freeze (it is the keyboard that freezes, this is how the game works normally and reacts to mouse movement). Who faced this and what could it be connected with?
