I just reformatted my computer, everything is alright except no sound. I opened control panel, sound and audio device, and it says I do not have audio device. I am sure I have a sound card and my computer had sound before I reformat it. Why does this happen and how can I solve the problem? If possible, please type in Chinese.
Thank you very much.

Oh, thank you for all the answers.
However, I think some of you misunderstand my question...
I am not asking to translate this into Chinese...
I am asking for solutions of my " no sound problem".
But still thanks for your answers...
