Tilde Key Unresponsive: If I Press The Tild Key Quickly As If I Were Typing Normaly, It Dose Not Register

ive been having problems with the tilde key on my Asus laptop. at first it was that it didint work at all, in games, in microsoft works, or notepad. i went searching online and disabled the driver for the eHome ir receiver (even though i dont own an ir receivers). after that i was able to use the tild key only outside of games. but heres the strange part, if i press the tild key quickly as if i were typing normaly, it dose not register. in order to use it i have to hold down the tilde key for about 1-2 seconds before it would spit out a stream of "````````````". then i could delete up to the first one. this is true for the laptops keyboard, and a wired dell keyboard i connected using usb.........
