Bonjour à toutes et tous,
 
Je fais appelle à vos compétences pour tenter de m'éclairer problème qui pousse mon pc à des bug a répétition  
 
A divers moments (en jeux, sur internet et parfois quelques temps après le démarrage) l'ordinateur  
- soit se met à afficher un écran éteint. Seul un redémarrage forcé permet d'en sortir.
- soit redemarre avec analyse du plantage mais sans donner d'éléments supplémentaires.  
 
J'ai un soupçon sur la carte graphique  (1 ou 2 fois des redémarrage ont eu lieu juste après un plantage du pilote.
 
Si quelqu'un parmi vous pourrait m'aider sur la question j'en serais fort reconnaissant.
 
Elmo

Bonjour, merci de détailler toute la config

Y a-t-il des artefacts (bugs graphiques) ? Le BIOS de la carte mere et les drivers vidéo sont-il à jour ?
 
Aussi, teste chaque barrette avec Memtest et si erreur détecté : SAV

Non je n'ai jamais de bugs graphiques.
 
Les pilotes de la carte graphique sont à jour.
 
Pour le BIOS j'avoue que là ça me dépasse un peu.  
Sur le net j'ai trouvé cette page (http://www.gigabyte.com/products/p [...] id=3164#dl) mais je ne sais lequel télécharger.

Aucune corrélation entre ces plantages et l'installation (propre !) de Win 10 sur ce vénérable P55 ??! (Au passage, un  i5 760 à 2.8GHz c'est criminel ! )
 
J'avais encore, il n'y a pas longtemps, une CM Asus P55 avec un i5 760 OC. Win 7 sur un SSD et Win 10 sur un autre. Le premier OS n'a jamais planté mais le second montrait des signes de faiblesse (BSOD) en cas d'absence de sollicitation. Attention aux pilotes installés en au auto par Windows ou manuellement (certains datant parfois de Mathusalem sur le site du constructeur).
 
 
Edit :
 
Of course !

J'ai effetué le test de la mémoire comme demandé (1h).  
Il s'est déroulé sans détecter de problème

W10 a été installé en upgradant W7 (petit doute sur la version antérieure) mais je ne peux pas assurer que tout a été fait "proprement".
Perso je préfèrerais retourner sur du W7.

C'est un pc que mon frangin m'a refilé, à l'époque je ne m'étais pas penché sur sa config

 
Bonjour, étant donné que ce problème semble aléatoire je crois qu'une vérification de la mémoire vive avec memtest86 pourrait vous mettre sur une piste. Sinon il se peut en effet que la carte graphique soit en cause (la RAM de la carte vidéo entre autre). Si vous avez un autre ordinateur a votre disposition, installez-y la carte graphique pour tenter d'isoler le problème. Bonne chance

Mieux vaut faire une installation propre de Windows 10 avec la bonne ISO téléchargée chez Microsoft. Quant au rollback vers Win 7, il est disponible pendant 31 jours.
 
Un problème de comptabilité OS/matériel n'est pas impossible. Un paquet de "vieilleries" sont apparemment passées sous Win10 sans aucun problème mais j'ai constaté IRL que certaines config n'étaient pas totalement stables/fiables.
 
Que donne l'analyse des fichiers dumps ? (Installe WoCrashed)

les deux derniers donnent ça :

9 crash dumps have been found and analyzed.
Read the topic general suggestions for troubleshooting system crashes for more information.

Note that it's not always possible to state with certainty whether a reported driver is responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.
