Sound cards enable your computer to play music and sounds through your speakers. Almost all new computers come with a built-in sound card. However, if your computer doesn't have one installed, or if you want to upgrade the sound playback or recording capabilities of your computer, you may want to install a sound card.
There are three types of sound cards: sound cards integrated on your computer's motherboard, internal and external sound cards. This article focuses on installing an internal sound card.
1.Unplug the PC and open the case.
2. Find the PCI slots on the motherboard. Most modern sound cards are designed with the PCI interface and connects to the PCI slot of your motherboard. A PCI slot looks like the slots on the following image.
3. If you have installed on your computer an old sound card, remove it before you put the new one.
4.Place your sound card on top of a chosen slot. Gently push down the card so it sits into position. Once the card is seated correctly into position, screw the card on to the case.
5. Finally insert the audio cable into the CD-IN socket. The other end of the cable should be connected to the Audio-out socket on your CD/DVD-ROM drive.
6. You should now close the case, turn on the computer and your operating system will detect that a new device was installed. Insert the CD with the drivers and follow the instructions on the screen.
