Teorias na Web

2. Ele fez algo com o "CRDA"

Meu sistema + plano de fundo

Dell XPS 13 com 12.02 pré-instalado. Eu consegui travar o meu sistema há dois dias (também problemas com wifi, nenhum wifi foi detectado) e como não consegui consertá-lo, pensei em usar o modo de recuperação da Dell. Não, eu sou capaz de ver wifi, mas eu sou expulso :(

2. Eu tentei verificar se drivers 2x são usados, mas se esse é o caso, eu nem sei onde procurar: (
