How do you record your computer screen without using a microphone or speakers?

im using a pretty screen capture

tool - PCHand Screen Recorder.

it could record anything on the

screen. and i think it is the perfect assistant to create

instructional video for u. what's more, it could record any audio

and keep synchronous with video. it is easy to use, i think it is

pretty good.

hope it could help u.
