Ciclo idle e rallentamenti pc

Postdi THECAPITAN » 14/10/07 17:13

Ciao ragazzi! ...Ho un problema davvero strano a cui non riesco proprio a dare una spiegazione.
Il mio pc subisce dei continui rallentamenti durante i quali qualsiasi operazione praticamente si blocca.
Durante questi rallentamenti ho provato a vedere il task manager.. ed ho scoperto un eccessivo utilizzo della CPU tra il 50 e 60%, e con ciclo idle che resta attorno al 90-99%. Certo, è vero che il ciclo idle del sistema deve essere sempre prossimo al 100%, ma il problema più importante si presenta sotto un'altra forma. Infatti, ogni volta che faccio partire un file audio o video, i rallentamenti sono accompagnati da forti fruscii audio ad intervalli irregolari. Ho effettuato diverse scansioni, ma niente di nuovo. Anche il log di hijackthis è pulito.
La cosa strana è che è successo tutto improvvisamente. Ho provato anche ad installare/disinstallare gli ultimi programmi ma credo che il problema sia stato generato da altri fattori. Posto comunque un log di hijackthis:
