Salve a tutti.
Il mio pc ( Windows XP Home Edition SP3 ) non ha particolari problemi, però spesso quando devo entrare in internet con google o aprire un sito in generale, si blocca completamente per circa un minuto e a volte addirittura sono costretto a riavviare per poter ripartire.
Una volta ripartito funziona bene per un pò di tempo ma poi senza preavviso ricapita.
Ho notato che accade più frequentemente dopo che il pc é rimasto acceso con lo screensaver per un pò di minuti.
Ho già scansionato il tutto come mi avete suggerito di fare ma non ho trovato nulla.
Quì sotto vi allego il risultato di Hijack per vedere se almeno voi trovate qualcosa.
Forlse il mio PC é arrivato alla fine dei suoi giorni? E' un pò vecchio.
Ciao e grazie.
