Sound sound no sound

Clear DayMy system recently has the sound problem. No more sound 0r voice
anymore.
I tried to plug off Creative sound card, and use the on board build in sound
also cannot.
Last time both can use. Today I found something: 20:51 2004-08-30

1. I went to Control Panel, click Sound and Audio Devices.
2. At Volume, it shows No Audio Device.
At Audio, three Sound playback, Sound recording and MIDI music playback
all show No Playback (Recording, MIDI Playback) Devices.
3. At Voice, also the Default devices of Voice device and Voice recording
show
No Playback (Recording) Devices.
4. When come to Hardware, I can see the on board build-in sound device VIA
AC97
Audio Controller (WDM) is there.
5. When I click Properties, from General shows sound device name, location
bus 0,
device 7, function 5. The Device status is: This device is working
properly.
from Properties I can see Audio Device, MIDI Devices and Instruments
and Mixer Devices.
But when I read Properties, I found something. All three the Status
reads:
"Driver is enabled but has no been started", so the " Settings" is not
function.
6. The last Hardware. I tried to use Roll Back Driver, then come to
:hardware Installation.
But it says " VIA AC97 Audio Controller (WDM) has not passed Windows
Logo testing
to verify its compatibility with Windows XP. What it mean? All along
was OK with XP, and now can not!

I did reinstall Creative driver failed, so I tried to use onboard sound
facilities.

Any high hand can help? Thanks
