Hi all,

I've just installed windows 8 64 bit Pro on my pc last month and i am loving its sleek and quick operation so much. BUt today when i am playing a fullscreen online games, the letters on the keyboard turns to numbers. i am a online game fan and also installed IObit Game Booster on my pc. the install process is vey successful and it has running onmy pc about half year. I've never expeienced this before upgraded to windows 8.
