Sound quit working.

TheEraserGI

Got an Acer Aspire AM3470G-UW10P. Had to install a NIC because the onboard LAN port died from a storm in the area. Now my sound is gone. Can someone recommend a solution on how to fix the sound or even what type of sound card I can get for it? Also, for some reason, I am unable to get into the BIOS on boot-up. I have tried all the normal buttons to push but can't get it to work. Thank you.

Please check if the audio device is detected in device manager.
Right-click on the Start button in the taskbar area and then click Device Manager to open the same. In the Device Manager, expand Sound, video and game controllers.  You should now see your audio driver name. Most likely you have Realtek High Definition Audio.

Right-click on it and then click Uninstall device option. You will now get the following confirmation dialog. Select Delete the driver software for this device checkbox and then Yes button when you see the confirmation dialog to go ahead and uninstall the device driver.

Restart your computer once and windows should automatically restore the driver.
Here's the weblink to install the Realtek audio driver :   Download
If you want to replace the audio card, you can get an Audio card that fits the PCIE card.
