Right, you see the butons on your keyboard that are like like a dot (.) and the one thats like a longer dot (,) this is called punctuation. And the shift key also makes letters CAPITAL.

As for waht you need to do to get a "gd clock", well, increase FSB until the system fails to boot properly and then increase voltage (vcore) to the CPU.
