Problème plantage du pc T.T

Bonjour,il y a quelque temps je viens de réparer ma CG ou le ventilo ne fonctionnait plus et maintenant l'apparition d'un nouveau problème.
Mon pc plante souvent lorsque je lance des programmes comme aion ou meme un antivirus. Une fois j'ai essayer de faire un scan antivirus mais il a planté au milieu du scan,la souris se fige et le son ne marche plus et puis reboot manuellement mais ce problème arrive parfois,défois sa marche parfaitement et défois non.Je vous le dit il n'y a pas de message d'erreur

Voici un rapport Hitjackis:
