Disattivazione scheda audio

[Ghena]

Da qualche giorno, quando apro il pc, la mia scheda audio veiene disabilitata.
Infatti non sono in grado di ascoltare musica e tutti i programmi relativi mi dicono che non ci sono periferiche installate.

MA in realtà la mia scheda è ben funzionante a dir del sistema...
