Recently i have encountered a problem with my keyboard, when i hold down a button it will stay held down, however then the input will switch between being held down and not rapidly. sorry if this is not well explained here is a GIF on the onscreen keyboard: http://imgur.com/WUtjIqQ.
this has become increasingly annoying during games as action such a walking or running will constantly stop and start.
any idea what has caused this and how to fix it.
