But when I downloaded a newer driver from the manufacturer website ,about halfway through installation process, the computer shuts off and restarts( not the same situation when playing wmv's and mp3's where it freezes and I have to power off) without seeing a message saying that installation complete like the case with the other drivers..This newer version of Realtek AC97, for some weird reason it will also install a media player called AvRack.And when the pc starts again ,there is no sound ,and the speaker icon (bottom right of monitor) is gone
Ok, this is the part that's confusing me. It sounds like you installed a new driver you downloaded from the net. Did you?
You then say this...
4) no I didnt uninstall anything....after the computer starts again , the speaker icon (bottom right ) is gone.So I go to"Sound and Audio Devices" in control panel and I find it the box faded.....So the only way I could get it back is by inserting the original motherboard CD and and reinstall the audio driver.
This makes it sound like you never installed anything but the driver from the CD.
In both the quotes, you say the speaker icon is gone
. So now... I'm more confused!
When troubleshooting a problem, you have to sometimes start from the beginning. That's why it was good that you installed Sp2. However, to continue troubleshooting, you should only install drivers from the CD that came with the motherboard. Even if you see a problem after doing that, that's ok... because, now we can look further without having to worry about updated drivers causing more problems. If you installed a new sound driver from the net, we now don't know if the new driver is conflicting with your board. We appear to be in the same place we were in the beginning of this thread with the only difference being it's with SP2 rather than Sp3.
When you installed the driver from the CD, what driver was it? Was it a Sigmatel, or AC97 version?
If you did in fact install a new downloaded driver, what I would do right now (if it were me), would be to run System Restore to the point before you installed the driver. Basically, go back to when you first had the system running with ONLY drivers from the CD. It doesn't matter if there are still problems with your computer sound, we just need to try to identify the driver issue.
After you go back, go to Start>run... type in winmsd
, click OK. Click on Components>Sound Device... post a screenshot.
