    Well after trying to figure out why I was missing letters on keyboard for the longest time.I found the problem to enabled hotkeys in HWinfo64.
    So what happens if you enable hotkeys in say the OSD RTSS tab.The hotkey works in game as intended but disables the actual key in a global setting such as virtual keyboard/internet/notepad.
    Fix was simple but not easy to find,so if you have the same problem most likely it is software related with a hotkey.
