Problemes graphiques et explorer

Bonjour, j'ai de nombreux problemes avec mon pc. Ils sont apparus en meme temps, ce qui me laisse penser qu'il ont la meme source. Je fonctionne sous vista sp2.

1er: explorer.exe ne se démarre pas tout seul au démarrage ( j'ai verifié avec regedit, la valeur est bien explorer.exe, et rien n'est décoché dans l'onglet démarrage)

2e: mes fichiers videos et photos ne peuvent pas etre lus. j'ai le son, mais pas l'image. Autre bizarrerie, quand je tente de visionner une image avec galerie de photo windows, ca ne m'affiche rien, mais lorsque je demarre une diapo, ca me les affiches !!!

3e: l'affichage de vista est différent. par exemple, dans démarrer, quand je survole documents, jeux ou autre, pas de design relief, reflet et tout, mais un banal surlignage. la croix pour fermer les fenetres, reduire et agrandir est aussi differente, elle est en design win98, mais la encore c'est bizarre, pas gris, mais bleu clair
Bref je ne comprend absolument plus rien, ca me soule largement car je cherche depuis plusieurs semaines sans rien trouver. J'ai spybot search and destroy, qui ne me trouve pas de virus, et je colle ci après une analyse hijackthis pour ceux qui le comprennent...
