Keyboard goes into a "mode" randomly

Hello,
Sometimes on rare but not too rare occasions, my keyboard enters this type of mode where every character I type is replaced by the same character but with an accent or caps locks. When I'm in game (mostly Overwatch), I press TAB but it shows me all the tabs I have open in a grey rectangle box in the center of my screen instead of the Overwatch scoreboard. Similarly, when I try to type in game nothing happens. Sometimes it works on other apps such as Viber. The most recent time this occurred was today, and this was the result : "SHé áLéáY Dmessaged". I tried to write "she already messaged" but that came up instead. Are there any fixes to this problem? It's very annoying having to restart my PC every time this happens.

I honestly can't be bothered to do any of the above, excluding the re-installation of drivers. I'll just say it's a K70 LUX and hope that someone has a similar problem and solution.
