Ornata Croma Acting up

So yesterday I was just doing my normal thing then I realized that my keyboard wasn't registering some of my keypresses. So for instance, I would try to type "Hello", but it would come out "Helo". This is for every key on the keyboard. I wouldn't think it would be the age of the keyboard because I had only got it earlier this year. Another problem was that it was spamming certain characters, randomly just out of nowhere and it didn't happen to offend. So I wake up this morning to write this and I have noticed that the issue is gone? no keys are messing up and it's fine? Would anyone know what happened to me as I am a bit confused .
