Blocage écran

Bonjour,

Je fais appel à vous car le pc (celui là même) d'un ami se bloque souvent, que ce soit à l'ouverture d'une page web ou d'une fenêtre windows. Le blocage est aléatoire.

Le CTRL+ALT+Suppr ne fonctionne plus à ce moment là, donc obligé de rebooter le pc par un appui long de la touche de démarrage.

Voici son scan HijackThis. N'y connaissant pas grand chose, je préfère attendre votre avis, en vous remerciant d'avance.
