I'm not sure why but somehow while playing the keyboard is mess-up or something else happens to my PC. When i start the PC for first time there is no any problem but after some period when i press "m" key from keyboard the value is 0 in text field where i'm trying to type something and some keys around have "m" key have numbers instead letters as value. when i unplug or shutdown the pc and start again keyboard is back to normal until something happen again. I'm looking for reason why this happens, is it hardware or software problem.
