Sound Card not recognised

[Guest]

am using XP SP2 on a Celeron PC with Mercury motherboard with onboard
audio. Recently the battery of the MB had to be replaced, after which the
onboard sound card does not work. The volume controls are greyed out in the
control panel and the volume button does not appear in the start bar.

The AC97 sound has been enabled in the BIOS, and the audio tab of the
'sounds and audio devices' in the control panel shows only three options,
modem #0 line playback, modem #2 line playback and modem #0 handset playback,
none of which seem to work. There is no yellow or red mark in the device
manager except for a HSP 56 MR modem. I use an external broadband modem so
this is not used.

It was working fine until the battery was replaced. Re-installing the
drivers from the mother board CD did not work.

Please let me know if there is any solution to this. Thanks in advance.

if the focus is considering the battery caused a problem then it is the
cmos/bios that may be causing you the problems. whenever the battery is
removed, the bios settings are reset to default. double check your bios
options with regards to audio, sound, pci,... are set to enabled. also,
check to see that the option to load bios in cache is disabled. there may be
an option that enables pnp by os.......


another thing to consider is that there may be a bios update as well. but
you need to go to your motherboards website and see if there has been
issued.....
