    First of all, welcome to Techspot.
    Maybe you should be a little more specific about your problem? What OS are you using, what did you download, and why do you think your download removed your driver?
    Have you looked at the Device Manager? If your sound card is missing a driver, you should see a yellow exclamation mark in the device manager.

    OK, that means you are missing a driver, just as you thought. Have you tried to search for a driver on Windows Update? To do this, rightclick on the entry with exclamation mark, select "Update driver software...", then select "search automatically for updated driver software".

    Can you see a name on your audio device, or just "Multimedia audio controller"?

    Sorry, it was just a little strange that the answer was almost what I asked, and the names are similar ;)

    OS means Operating System, like Windows XP or Windows 7. There could be drivers available for download, if you could tell me what operating system you are using, and a little info on your computer (laptop or desktop, what brand and model number, if any) I can look it up for you.

    Ok, that helped, now I know you have a Dell desktop computer, but it would be useful to know what model (like Dell Dimension 2400). You should go to and follow the instructions ("Choose by service tag" or "Choose a model"). Then you can download a sound driver OR post your model number/Service tag and I will look for a compatible driver.

    According to your service tag you have a Dell dimension 2400.
    You can try to download a driver here. Install it, reboot and let me know if it works.

    If UDI doesn't work then check the BIOS. Make sure that the on board audio is no disabled, which I doubt is the case, but give it a try.

    go to computer\properties\Device manager\sound
    check if your audio device is disable , and if it is enabled then try to reinstall the audio driver.
    after that if nothing happen try to reset the bios .
