i installed a asus m3a motherboard yesterday and everything works brill. the only problem i had was an annoying crackle coming from the satelite speakers, and everytime you moved the mouse it made a noise. even the clock ticking on the desktop. so went into the speaker settings, found a slider that said pc beep and turned it right down and the crackle dissapears with no loss of volume to music being played. so i just wondered whay is pc beep and what is the slider controlling. if i dont respond to any messages after 9.30 i will later on, work calls. i would like to know the answer, i googled it, but nothing.
