Why does the keystroke sometimes fall off when pressing the space bar?

Question

Keyboard

I noticed such a thing when you play a game where you have to run with the shift key pressed and frequently pressing the space bar, that pressing the space key disappears from the key responsible for running, i.e. the character stops running and stands, but I did not release the key. After pressing the run key again, he starts to run, but sometimes when you press the spacebar, the character stops again. Everything was fine before. I tried to reinstall the motherboard drivers and installed the video card driver to the heap. Also this situation is not related to a specific keyboard. Because At home I have 2 keyboards, one mechanical, the other old membrane. Initially, there was a membrane keyboard, but when I started playing, I noticed that pressing the button subsided. I changed the keyboard, I thought everything would be fine, but the problem remained the same. On thisThe site checked the operation of pressing the keys and yes, indeed, when you press the spacebar, sometimes the button press disappears, but I keep this button. Who knows what could be the problem? Now launched a virus scan, a little later I will unsubscribe about viruses.

I myself understood what the problem was, it was very stupid of course, but the program called "punto switcher" was to blame. Maybe someone will have the same problem.
