I've seen this happen with onboard video cards but the details are hard to find about your PC.
Hi,
i've been having a problem with my keyboard in PC games , i'm using windows 7.. it's all going fine during the gameplay all button are working fine .. but in the control setting menu or whenever a tip shows up buttons are undefined .. see the photo to know what i mean....

that's from "max payne3" .. the game is working well and all buttons are working as they should but as you can see they are undefined in the controls menu or whenever a tip shows up -although they actually are working- , note that this only happens with the letter keys the numbers and "ctrl,alt,shift" are just fine..
also note that i've tried in other games and still the same problem , I've also tried another keyboard and still the same issue..
