Ok. Re posting this in a different way. Think something accidentally got uninstalled. Have no sound whats so ever on the computer. When I go into device manager there is a yellow question mark in other devices. Not sound,video,game controllers. When I right click the ? mark, there are 2 things that drop down. One says Audio Device on High Definition Audio Bus and two says Video Controller (VGA compatible). They GIVE me the choices to update; disable; & uninstall.
When I click properties it says to reinstall.
Says this... The drivers for this device are not installed. (Code 28)
To reinstall the drivers for this device, click Reinstall Driver.

If I try to reinstall it asks me for a disc. I do not have one. Not sure what I have to reinstall. DriverMax was not that helpful. I don't really want to keep TRYING these driver help downloads. I just want to know what exactly to do. This is the info I got from my computer. I am sorry I don't know more than this. It is not our main computer, thought it was rebuilt. I really appreciate any help. My kids are driving me nuts wanting sound for their games, lol. Thank you!

I am online for a while if I can answer anything else about this in order for your help. Thanks again. Is it onboard audio or do you have a separate sound card? If it is separate, you could look on the card itself and find the manufacturer and model type and go to the manufacturer's website and get the driver straight from there. If it's onboard, you should be able to go to either the motherboard's manufacturer's website or the PC manufacturer's website and get the drivers from them. Go to the following page on the motherboard manufacturer site, and download the audio driver from the downloads section.

It sounds as though the video driver is not installed either, so you may want to get that driver from the same page while you are there.

Good LuckLooks like a fresh install. Go to the ECS website, download the drivers for audio and graphics (oh, yes, you're graphics also need a driver for the games =P), install and you're done.
