Keyboard typing double letters

[chriswa2002]

Hey, i didn't know where to put this forum but, my keyboard is just typing double letters on key U, ive only had issues with that letter, ive had this semi mechanical keyboard (skorpion K10) like for 6 months now, or less. So lets say im gonna type "starbound", if i type too fast it types "starbouund", it only happens in certain words, it does not happen in all words, its super weird.
Thanks in advance!
