da qualche giorno il mio pc frizza un po' quando gli pare. E come gli pare, dato che alle volte si impalla lo schermo (tipo fermo immagine) e alle volte lo schermo si disattiva proprio.
Io credo dipenda in qualche modo bizzarro dall'alimentazione, perchè sembrerebbe non succedere quando il cavo è staccato e perchè ho trovato che ci sono problemi con ACPI. E' mai possibile?
