Hi there,

I have a pentium 4 desktop computer at home, well it was running fine since 2 weeks... i had remove hard disk to place on another computer as slave and the re-inserted the hard disk back, but since then, i don't have any audio devices on my computer, the audio is integrated. When i go to Control Panel/Sound and Audio Devices there is no audio devices.

When going to the audio tab the Sound Playback and Sound Recording are grayed out and i can't choose any of them.

I tries to go to Administrative Tools/Services to check whether the Windows Audio Startup type was set to automatic and it was correctly set to automatic.

I tries to install several sound drivers like Realtek and SIS but the problem is still not resolved.

Here is the information for my Motherboard:
