You may need to update the software drivers. Make sure you computers automatic updates are on. To see the status of the drivers, go to start, control panel, and sound. There is a drivers tab at the top. Click the link that says check for updates. Hope this helps.

Hi there.

If there is no sound coming out from your desktop, make sure that the audio card driver is installed or updated. To check on this, go to Device Manager ( START - Right Click My Computer - Properties - Hardware - Device Manager). See if there is a yellow exclamation point before AUDIO. If there is, then you need to download the driver from the Emachines website.

Thank you!

What I could recon from your question is that your audio driver is not installed in your reformatted PC.

Please be informed that any Driver software depends upon the PC make, Motherboard type and Operating System. You need to know all the three information's to do get going.

Please find the Driver software's of your Audio and video inside the installation disk provided with the PC at the time of purchase. As you have not mentioned your PC make I am unable to give you the direct download link. However you can download the same by visiting the website of the company that manufactured the PC.

Even here you need to be careful to download the correct software for your PC. You need to be exact with the PC make and Model number and the OS that you are using.

To install just Double clock on the driver setup.exe file and go on clicking 'Next' until you get the 'Finish' option and restart the PC.

Surely you do not have sound drivers installed on your computer. Google your computer model followed by "sound driver" and over the results, enter manufacturer's official website. Download the sound driver, intall it, and check the sound operation.

try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
