page blanche pour restauration system

J'ai désespérément chercher (mal sans doute) une solution à mon problème.
Je veux effectuer une restauration system et je n'ai accès qu'à une page blanche "restauration du système". ceci est arrivé après que j'ai voulu installer sp3 qui a avorté.. mais en m^me temps IE7 tentait de s'installer... rien n'a réussi et la restauration a disparu...
j'ai scanné avec : ad-aware, avst et avg et spybot, j'ai nettoyé avec ccleaner et turnup... rien n'y fait... j'ai même eu des déconnectioons de messenger avec le message : erreur sur IE... j'ai tenté de réinstallé IE 6 et/oi 7.... rien.
J'ai fait une tentative en mode sans échec... tjs rien.
De plus je trouve que mon pc rame depuis cet ......incident.
Je joins un rapport hijackthis après nettoyage.
