Ordinateur s'eteint navigateur ouvert

Bonjour,
mon soucis est le suivant:
Mon ordinateur (windows 7-32b) s'eteint dés que je lance un navigateur.
J'ai un ecran bleu direct avec "bad pool header" inscrit.
Le soucis est que le texte de mes fenetres a disparu.
Malgré tout j'ai réussi à faire un SCAN via Hijackthis et ZHP
Pour Info, la vérification du C: et de la mémoire n'a rien donné. La température (via speedfan) est correcte 42°.

Je transmet le fichier de Hijackthis sur ce post en espérant que quelqu'un est une solution:

Logfile of HijackThis v1.99.1
