Salve, come dice il titolo del post ho spesso e volentieri System che porta la CPU al 100%, principalmente quando apro qualcosa di nuovo, rallentando anche molto il pc specialmente se apro una chiamata, un video o photoshop. Praticamente arriva anche a paralizzarsi per pochi minuti.
Il portatile lo uso per lavorare (faccio la disegnatrice e mi servono Photoshop e Flash) ma non posso fare nulla in queste condizioni.

Ho cercato informazioni su internet riguardo ntoskrnl.exe ma ho trovato solo informazioni relative al BSOD (cosa che per fortuna non mi succede), ho comunque provato a seguire qualcuno dei consigli ed aggiornare i driver ma non è cambiato niente.

Ho seguito i passaggi che devono essere fatti prima di postare e i vari antivirus, malware bytes ecc non hanno trovato nulla di strano.
Ecco qui il log di Hijackthis, spero di avere postato in modo corretto e che si possa risolvere il problema. Ringrazio in anticipo chi mi aiuterà.
