The search itself sound card, that is a separate charge, mounted on her chips, it is necessary where placed and the motherboard — its connectors are in most cases installed all the expansion card. To gain access to the motherboard of a desktop computer, you must remove the left panel on the system unit. Do this by unscrewing the Phillips screwdriver on the back side of the chassis the two screws with which the side surface of the housing fixed thereto.

Among these expansion boards and look for your sound card.
It is likely that it will not appear there — most modern motherboards have built-in microchips for sound processing and do not need a separate sound card. To know the type and version of this built-in sound processor can be the labeling of the corresponding chip on the motherboard.
To open the system unit is not necessary, if you only need information about the computer installed in a separate or integrated sound card. This can be done programmatically — for example, with the help of AIDA64, provides a huge amount of useful information about installed in the computer hardware, used settings and current status.
Information about sound card, look in the section called "Audio PCI/PnP" section "Multimedia" menu. For example, the data line on the built-in motherboard sound processor might look like: Realtek ALC1200 @ ATI SB700 — High Definition Audio Controller PCI.
