If your computer has sound problems it could be caused by one of a number of things. Sometimes it is caused by formatting your hard drive. Other possible causes are:
1. A virus that has infected your system
2. Bad installation of your sound driver
3. A configuration problem with your sound card
4. Or simply a problem of compatibility between your operating system and the sound device that you are currently using.
In either scenario, you can try to fix this problem by following the steps below:
Check that the audio controllers

Windows 8, move the cursor to the bottom right corner to open the Charm Bar and select Settings. Then click PC Info and then click Device Manager available in the upper left.

If no yellow exclamation point appears, then you must check:
Speaker Connection (jack properly threaded into the green socket on the PC, power-control ...)
Windows mute feature (small speaker in the taskbar),
the sound heading in the control panel (explore everything everywhere, do not hesitate).
If the audio controller appears as the name of the Device High Definition Audio Controllers, under the audio,video tab, and Device Manager a driver for the audio controller is missing or not recognized properly.

Start Menu> Control Panel> Performance and Maintenance> Administrative Tools> Services
Start Menu> Menu "All Programs"> Administrative Tools> Services
For Vista / 7, click on the blue circle at the bottom left, type Run in the Search bar and confirm with Enter. In the Run window, type services.msc and confirm with Enter.
For Windows 8 (valid for Vista / 7 as well), press Windows Key + R simultaneously to display the Run window, type services.msc and confirm with Enter. In the Services window, check the "Windows Audio" service is started automatically.
If it is not, right click it and start it.

If you have a backup partition, it is possible that the drivers are on it.
