Ho provato a riavviare il pc e mi è ritornato il messaggio di errore del driver e che si è ripristinato... che devo fare?! che può essere?

Se pensi di avere una qualche "infezione" dovresti andare a postare la cosa nella Sezione specificamente dedicata a "Virus, sicurezza e privacy".
Il tuo problema avrebbe maggior visibilità, in questo modo, precisamente agli occhi di chi più se ne interessa.

Devi aprire un altro thread (nella giusta Sezione) e ri-postare quel che hai postato qui.

Allora in prima istanza ho fatto il riavvio è tornato poi quando ho proprio spento e poi riacceso non è più tornato.

che devo pensare?!

Quoto Logic: se tutto funziona, è il caso di sentirsene contenti e seguitar così.
