Ecran bleu et reboot, erreur WHEA_UNCORRECTABLE_ERROR

Bonjour, je me permet de poster ici pour trouver une solution à mon problème.
En effet je possède depuis 1 semaine cette configuration Gamer achetée d'occasion.
- un boîtier Cooler Master Storm Enforcer,
- une alimentation LDLC BG-500,
- un processeur Intel Core i5-3570K,
- un ventirad Noctua NH-U9B SE2
- une carte mère Asus P8Z77-V LX,
- deux barrettes LDLC de 4 Go de RAM DDR3,
- une carte graphique Sapphire Radeon HD 7850,
- un disque dur Western Digital Caviar Green de 1 To,
- un lecteur/graveur DVD Lite-On.

Après nettoyage et réinstallation du système je m'aperçoit que des écran bleu et des reboot intempestif apparaisse que se soit au repos ou en jeux.
J'ai donc déjà essayé et remplacé l'alimentation, le disque dur les ram et effectué des test avec Memtest chrystaldisk .. sans résultat, je pense donc que le soucis viens de la carte mère.
Je n'ai pas effectuer les mises à jours de Windows 7 ni son activation par manque de temps et d'envie mais l'installation est propre (tester sur W7 et W8.1).
Les températures sont très correctes.
En vous remerciant par avance pour vos futur réponses.

Voici donc les rapport Whocrased.
