Alright, i am using a Microsoft Digital Media Pro Keyboard, and it was working fine before, but now, whenever i play a game, or type, the keys seem to lag, severly. While racing and beginning a turn, it will either delay, or go right away but waaaay too long and send me into a wall. Or when playing a shooter like Crysis, it lags and causes me to just keep running. Please, can someone help me? Should i get a new keyboard?
