Ordi se fige, qui peut m'aider svp ?

Bonsoir.

Voici les symptômes de ma machine :
Après quelques minutes, l'ordi se fige et le reboot est obligatoire.
J'ai également Linux installé et n'ai aucun problème sous Linux ce qui me fait

penser que mon problème n'est pas hardware.
J'ai essayé de démarrer en SafeMode mais pas moyen, l'écran reste bloqué avec le

curseur qui clignote en haut à gauche.

Je crains maintenant une infection virale.
Voici le rapport Hijackthis.
Quelqu'un peut il m'aider svp ?
