When I type the letter "o", it typed with number instead "o9". I noticed that. I already uninstalled the driver (PS2 keyboard) and restart but no luck after all. I tried to clean the keyboard, not fixed also. other key is working fine (i.e. row: Q, A, Z. L,>) aside from 9, and O. When I type the Number 9, it also displays o9 instead of just the number 9. and o9 instead of just the letter "o".
