Keyboard Keys Randomly Sticking

My Name is Jeff(Jack) - Nov 22, 2015 at 08:33 AM
When im playing a game, my keys keep randomly sticking, my keyboard is perfectly clean. When i click super fast and hold a key, the key i press Toggles or something.
When i click too fast it makes my game freeze, exit or not respond.
Is there any way to fix this annoying thing?
