ordinateur qui redémarre tout seul

Bonjour, j'ai déja posté ce mail mais je me suis trompé de page donc on m'a conseillé de créer un nouveau sujet, désolé si ca vous a dérangé! alor voici mon log mais je n'y connais rien!! a noter aussi que mon antivirus avastar ne voulait plu marcher tout à l'heure et il y avait un message d'erreur RPC
voila, merci d'avance
