Crash athw8x.sys Windows 8

Bonjour,
depuis quelque temps, mon PC redémarre inopinément avec un message d'erreur. J'ai mon PC depuis 1 an et demi et les premiers problèmes ont commencés il y a environ un an, mais j'ai eu des périodes de 2/3 mois sans aucun problème entre temps puis des jours avec 5 crash dans la même journée.
J'essaie donc de résoudre enfin ces problèmes, je dis ces parce que j'ai du avoir une dizaine de message d'erreurs différents en tout. J'ai fait un rapport WhoCrashed et voici ce qu'il me dit pour les plus récents :

J'ai réinitialisé mon PC il y a quelques jours pour voir si ça irait mieux mais ça n'a rien changé. D'après WhoCrashed il s'agirait d'un problème avec le driver athw8x.sys mais je n'ai rien trouvé sur internet pour le mettre à jour. Si quelqu'un pourrait m'aider.
