Ecran noir 30 seconde au démarage.

Bonjour,

On m'a conseillé de venir poster mon problème ici, ce que je fais.

Tout d'abord merci d'avance de vos réponses !

Depuis quelque temps (hier après midi précisément), lorsque j'allume mon PC portable, il s'allume, le logo de chargement W7 s'affiche, et quand il a finit, l'écran devient noir, je ne peux rien faire, et au bout de 30 ou 40 secondes, il s'allume normalement, en arrivant sur le choix des sessions.

Certes ce n'est pas trop dérangeant, mais cela reste un problème, je trouve cela étrange car je n'avais rien fait de particulier sur mon PC avant la première apparition du problème.
Depuis, j'ai fait une mise à jour de tout mes pilotes, j'ai fait des scans de mon PC à l'aide d'Avira et de Malwarebytes, mais le problème est toujours présent.

Une petite précision qui s'avérera certainement inutile, mais après toute ces mise à jours et scans, un autre problème est survenu : Je ne pouvais plus accéder à internet ! J'étais connecté à mon routeur, mais je ne pouvais rien faire. Il s'est avéré qu'en fait l'option "utiliser un serveur proxy" s'était activée d'elle même, et je l'ai donc désactivé, et ais retrouvé internet.

Voilà, quelque info sur ma config qui pourrait être utiles:

MSI GE620-216FR
Intel Core I7-2630QM
Nvidia GeForce GT540M
8GB RAM DDRIII
Merci d'avance !

Voilà également le rapport fait à l'aide de hijackthis :
