hi, i have an asus g73sw. i had the same issue where both of my shifts stopped working, however more than just the shift keys were having issues. after ordering a new keyboard and experiencing the same problem i began to fidget with the component on my motherboard that my keyboard plugs into. i have gotten all of my other keys to work save for my shift keys. i have installed the driver and checked everything mentioned and still havent been able to solve the problem. can somebody tell me if i will be able to replace the individual component or will this require me to replace the motherboard as a whole *question mark*
