So I have my K95 Plat (AZERTY) for about a year now and some months ago my keyboard just stopped working. The RGB always kept working but I couldn't press any button. The buttons that I was holding, were still "being hold", like in a game where I press the key to go forward and my Keyboard disconnects, I kept going forward. To fix it I had to pull the USB cable out and back in, then hope it would work, if not, I had to keep trying again. It fixed itself after a week but now I have the same problem that I had before, but worse. Now it happens when I start my PC and a LOT when I'm playing games/writing documents. It is very annoying when it disconnects when I am in the middle of a game.
Also I don't get a sound when it disconnects
