Buongiorno. Il computer non presenta particolari problemi, tranne uno spegnimento improvviso una volta al mese circa (cavoli......che sia femmina???), che comunque non causa grossi guai. Lo strano (ma forse voi mi direte che è normale), è che ogni tanto emette un rumore tipo quando si attacca o si disattiva una periferica esterna, e ciò mi da l'impressione di qualcuno che mi stia ravanando dentro..... Allego il file. Grazie per le eventuali risposte. Ed

Il log mi sembra pulito, che il computer si arresta una volta al mese è proprio strano, Windows non smette mai di stupire.

Prova a fare una scansione con MalwareBytes
