Je n'ai plus de son, carte mère !

Bonjour à tous,

Il y a quelques mois j'ai dût reformater mon PC pour cause de virus.
Depuis ce jour, je n'ai plus de son. Je me suis donc renseigné et apparemment cela proviendrait de ma carte mère.
J'ai regardé dans mes CD et je ne trouve pas de CD correspondant à la carte mère. Ensuite j'ai fais une analyse de ma configuration.
