Rapport hijackthis

Bonjour,

J'ai un soucis avec mon ordi : il reboote une ou plusieurs fois au démarrage (parfois 6 ou 7 fois d'affilée) et marche ensuite sans problème particulier.
J'ai essayé de mettre le pack 2 de windows pour utiliser IE7 mais j'ai un message d'erreur :
"c:\windows\system32\ntdll.dll ouvert ou utilisé".
J'ai fait cleanup, adaware (qui me trouve le trojan TR/Dldr.DNSChanger.GEN) et lancé un scan avec antivir (qui ne trouve rien à part :
"H:\pagefile.sys [WARNING] The file could not be opened!"

Voilà le rapport hijackthis :
