Bonjour,
 
Je viens à vous dans l'espoir de trouver une solution. (enfin, mon épouse, ci joint le copier/collé d'un topic crée sur un autre forum, sans réponses. Si vous pouviez nous aider, cela m'arrangerai, ca me gonfle un peu de lui avoir offert une config de gamer, et de ne pas être foutu de le faire tourner (et ca la gonfle encore plus! merci   ).
 
Lorsque j'entre en jeu (GW2 pour être précise), le pc crash systématiquement. Le code erreur correspond à un problème de driver. Mais tous les drivers ont été mis à jour. On a vérifier la ram; le cpu, tout est ok. Je ne sais plus quoi faire.
 
Voici ma config :
 
carte mère MSI Z170A GAMING M7
processeur Intel Core i7-6700K (4.0 GHz)
carte graphique MSI GeForce GTX 980 Ti GAMING 6G, 6 Go
DDR4 G.Skill Ripjaws V 2 x 8 Go, 2666 MHz, CAS 15
SSD 240 Go SATA III
hd 3 x 1 To
 
Système d'exploitation : Windows 10
 
Le pc fonctionnait parfaitement jusqu'au formatage qui a précédé son acquisition (je l'ai vu tourner sur Dying Light). La config a moins d'un an

Je viens de faire une analyse avec WhoCrashed. Voici son rapport :

Conclusion
2 crash dumps have been found and analyzed. No offending third party drivers have been found. Connsider using WhoCrashed Professional which offers more detailed analysis using symbol resolution. Also configuring your system to produce a full memory dump may help you.
 
 
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.

Bon après tentative de fixer le problème du ntoskrnl.exe, le pc ne plante plus mais le jeu fige et j'ai plus accès à rien à part le menu via la touche windows. Des idées?
edit : j'ai parlé trop vite.
