Pb démarrage, navigation pc--aide et conseils rapport hyjackthis

Bonsoir,
Je suis en train de nettoyer mon pc, suite plusieurs dysfonctionnements:
exemples :
L'ordi s'éteint tout seul
Plus aucun fichier supprimé ne passe par la corbeille
Mon bureau a disparu (plus d'icônes, je le retrouve dans le poste de travail)
Plus possible d'ouvrir d'invite de commande (elle se referme en une seconde)
Plus possible d'éteindre/redemarrer correctement (je dois fermer la session puis desactiver)
A chaque démarrage, mes documents et une fenetre de script s'ouvrent ..
J'ai des phases de deconnection toutes les secondes
Je crois que c'est tout mais je doute ..

Tenté de réparer tout ça via la machine, sans succès.

Lancé un scan hyjackthis (l'analyse informatique me detecte des anomalies mais je voudrais vos conseils avisés)

voici le log

d'avance merci,
Enna

Bonsoir,
merci de ta réponse tout d'abord.
J'ai fait ce que tu m'as proposé, malheureusement le rapport est vide, rien de detecté apparemment .
Pourtant mes problèmes subsistent.
