K90 Q key acting up

Hey guys, I've had my K90 for about a year and 7months now. Lately, my Q key has been acting up. Every time I press Q, random letters show up. This is what shows up most of the time when I press Q: eiopqruw. I literally have to delete the other letters just to get it. It's happened twice so far. First time, it just went away. This time, it's not going anywhere and it's driving me to insanity :(

Looked it up and I cant find anything about it. Any ideas?



This is me just pressing q:

eiopqruw+789

+9eiopqruw78

+89eiopqruw7

eiopqruw+789

+eiopqruw789

eiopqruw+789
