I have been having an issue with the keyboard on my Lenovo G50 where I can not press more than one key simultaniously. This is a recent occurance and it has been seriously affecting how I play. I go to strafe left or right or move forward or back and for some reason it will quit registering the key that I pressed after about 5 seconds, if I press another key, or if I press the Ctrl key. Anyone know what might be wrong?
