I had Windows XP reinstalled on my computer hard drive. When I got my computer back. The sound was not working. When I went to My Computer/ Hardware Devices, there were 3 yellow question marks on:
SM Bus Controller
PCI Device
Video Controller

Do I need to delete these and try to reload them. If so, is there a process or Disc i need to do this?

Also, (Originally) why would I not have sound?

Hi daniels012!

In device manager, right click each of these and select uninstall, restart the PC. Windows might load the correct drivers on it's own, otherwise we'll need to do it manually.

Sound isn't working, because the drivers for your sound card are not installed. Is it a prebuilt PC? Some specs couldn't hurt.:)

Also, who reinstalled Windows for you, a tech?

as far as loading the drivers manually
i always use unknown device identifier if ive known someone who has re-installed the operating system on thier machine but had no driver disks.
software can be downloaded from here and its freeware

just run it and it should give you a list of models and makes of all your components, then just goto the manufacturers website of your video & sound card etc and download the drivers and install them on your machine.

Here you go: T-5212 - Just click on downloads, ignore the BIOS and SATA downloads:D

These are all the drivers you need for your model - that's why I asked if it was prebuilt:)

I am not totally sure what to do, so let me ask.
Do I just download to the Desktop?
If so, do I just double click the file?

The Bus controller should get installed alongside the chipset driver

Perhaps you just need to restart the PC. If that doesn't work, download the file in the link above, uninstall the SM bus controller, install the driver from the file and restart the PC.

BTW, do you have sound?

I did exactly as you suggested, no luck. When I was unzipping it wanted to know if I wanted to overwrite every file. This is how I knew I had already downloaded the correct file.

No sound, it says "No Audio Device"

Alright, Start>Run... dxdiag and ENTER. What does it say under audio (sound)?

Let's try to install the sound card drivers in safe mode, might not work:D
To get to safe mode, restart your PC and start tapping F8 right away. When you get to the menu, select "safe mode with networking".
Open device manager, uninstall the PCI device (if it's still a question-mark). Next, under "sound, video and game controllers" check each entry - if you find anything related to sound, uninstall it (you won't get an option to uninstall for everything - in that case, ignore it and move on).
Delete the sound card drivers you downloaded and download them again. Run the setup, let it overwrite everything. Restart the PC (normally)

Hear anything?:eek:

did you run the unknown device identifier?
is the pci device mentioned listed as your audio device in the program?

may verywell be that you need to replace soundcard, assuming this is a desktop and not a laptop?
or is it onboard sound?

what is this?

It is a desktop with speakers that plug into the back as well as USB (I assume is for speaker power)

In my last post i suggested downloading and running "unknown device identifier"
as it will give you specifics on all components make and model etc in your machine, so that correct drivers can be found and installed.
but if this isnt even picking up your sound card then it may be a new sound card needed.
