keyboard problem

my keyboard does not respond when i type and it only works when i play gcph but i cant type in chat box, does anyone knows how to fix this problem?
i'm using on-screen keyboard when i type.:confused:

Oh..try typing in notepad if it types.

If it doesnt, theres a problem in your keyboard

bad connection or the energy is tangling with the other usb devices..try moving it to another port..o and remove the pic/spoiler it is too big.

i did experienced this too xD.
first of all ill just want to remind you don't boot your pc having a USB.
second of all try each key on the notepad. C:
