The personal computer has evolved beyond the utilitarian purposes for which it was originally created. Computers today have become personal entertainment machines, capable of streaming music and video from the Internet, playing DVDs and displaying games with 3-D graphics. One important component to enjoying music, movies and games is the audio; if the sound is too low, you may have trouble hearing. Fortunately, increasing the volume on your computer is an easy task.

Click "Hardware and Sound" from the Control Panel menu.
Select "Adjust System Volume," beneath "Audio Devices and Sound."
