I have a problem when playing games such as Deus Ex -Human Revolution or Call of Duty 4 : Modern Warfare, where when using the WSAD buttons to walk, a directional key will "stick and continue to force me in that direction. The only way to stop this now is to pull up a game menue and then exit back out of it. My keyboard is clean. This is strictly happening when playing these games. Any ideas would be appreciated. I have googled this topic for hours with no solutions.
