Pb de redémarrage intempestif

Bonjour,

Je me trouve actuellement dans une situation délicate mon PC redémarre tout seul est intempestivement avec un message d'erreur qui me dit :
" Plug and play a cessé de fonctionner "
J'ai donc pensé a une infection car le ventilo tourne le PC et quasi neuf et n'est pas poussiéreux et les drivers du moniteur sont à jour et ne présente pas de défaillances visibles. J'ai essayé de détecter le problème, rien avec un scan online bitdefender 2010 et trendmicro. J'ai trouvé quelque trojan avec a-squared que j'ai supprimé. J'ai donc lancer un log hijackthis et je suis la pour demander votre aide pour l'interprétation du log que voici
