My computer switch on and off the sound is small, the expert help me ah?

The first step, look at your sound has not opened, or there is no power connected to the sound, haha this is the most pediatric approach, but also the most easily ignored The second step, look at your computer's audio software has not been set to mute, but I think you will not be so stupid, huh The third step, right-click on my computer to open the device manager, check your sound card driver has been lost, or mismatch The fourth step, open your motherboard bios small settings to make the boot mode as the default mode of the computer, otherwise even if the above three steps are resolved will not have a startup thud. Open your motherboard bios, a small setup, so that the boot mode is the default mode of the computer, otherwise, even if the above three steps are solved, there will be no startup thud The above problems are all solved, probably your problem is solved.

Please accept if you are satisfied
