Il mio pc presenta i seguenti problemi:
1) La procedura di accensione si completa dopo vari tentativi in quanto il pc ripete varie volte le operazioni fino a quanto (dopo circa 10 minuti) non riesce a completarla.
2) Durante l'utilizzo del computer e durante la navigazione in internet il pc si spegne e si riaccende da solo.
3)Il pc non installa più nessun programma anche se scaricato da cd e non completa alcune operazioni tra le quali ad esmpio Reg Seeker.
Allego il LOG di hijack sperando che sia utile per risolvere il problema grazie ai vostri suggerimenti.
