I've recently got back into playing some PC games, however yesterday I started experiencing some weird problems. Whenever I'm inside a game, the keyboard either chooses not to work at all, or it registers keypresses very rarely. I have no idea why this happens.
I can type completely normally outside of games, and have tried using another keyboard to no avail. This indicates a software problem somewhere, but I have no idea how this could have happened or how I could fix it.
I've seen various bits on the internet of people with similar/the same problems however none are conclusive.
