Problèmes écran bleu

Bonjour,

Depuis au moins 1 an j'ai un problème d'écran bleu sur mon ordi portable.
Je suis sur Windows 10 Famille .
Mon ordi est un acer avec processeur x64; et Intel(R) Core(TM) i3-4005U CPU @1.70GHZ.

Du coup pour les cartes graphiques :
Intel(R) HD Graphics Family et
NVIDIA GeForce 920M

J'ai installé WhoCrashed pour avoir des détails sur les crashs.
Voici les résultats :
crash dump file: C:\WINDOWS\Minidump\050917-31656-01.dmp
This was probably caused by the following module: nvlddmkm.sys (nvlddmkm+0x21C47A)
Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF806E622C47A, 0xFFFFCF8053F28418, 0xFFFFCF8053F27C40)

Bug check description: This indicates that a system thread generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 368.39 , NVIDIA Corporation).

The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.


Du coup je ne sait plus trop quoi faire et c'est pourquoi je pose cette question.

Si vous avez des solutions je suis preneur.

Merci
