I've had my keyboard for only 4 months and it just suddenly started repeating the keystrokes too fast. I would press it and then it would cause 2 or 3 more strokes. I just woke up and this was happening. Also, I cannot play some games because of how it causes multiple inputs and my character ends up stuttering and moving like that. I have tested this keyboard on other computers and my only guess is that it is a problem with the keyboard.
