try this?u can enter bios when open the pc and go to the "others" section.
there is a "System Beep" under that section, disable it and enable it again. then save the changes and restart.

my pc always like that :P whenever i install new software or do some changes, the sound disappears.

maybe this can work :D[七七 (9-7 11:39, Long long ago)] [ 传统版 | sForum ][登录后回复]5楼
