Il pc di blocca dopo 5 minuti

[galdaron]

Ciao a tutti, da qualche giorno ho un problema con il mio pc. Si avvia normalmente, avvia i programmi dopodichè dopo massimo 10 minuti si blocca. Funziona solo il mouse e niente più. Ho utilizzato il file hijackthis.log e riporto il file di log:

Scusa che significa ? Devo rimuoverle con il programma ?

Perdonami non sono molto pratico.
