This is a language problem. Somewhere somehow you computer is tring to comunicate with a keyboard of forign design, like Japanesse. I have seen this problem before when I loaned my PC to my Korean friend who used his own keyboard while talking to his family back home. I didn't fix it however, he came over and switched everything back to normal. But thats your problem. Just dont know how to fix it.
Life is like a womens underware. Hard as hell to get into, but fun as sin once you do.
