Plantage pilote graphique AMD

Bonjour à la communauté.
je viens vers vous suite à un plantage de pilote graphique (carte sapphire R9 280Tri-x).

J'ai acheté un nouveau SSD pour mon système W10. Je suis passé d'un samsung 120 Go à un crucial 240GO. Fait j'ai un clone à l'aide du logiciel "acronis true image for crucial". j'utilise le micrologiel et je passe le SSD en cache comme demandé (à vrai dire je ne sais pas ce que c'est).
Je n'ai rien changé d'autres.
J'ai utilisé l'ordinateur sans soucis durant une journée. Le lendemain j'ai commencé les plantages à répétition avec BSOD.
vu sur les forums, j'ai utilisé le logiciel WHOCRACHED pour identifier le pilote en cause. J'avais déjà un doute sur le pilote graphique. Il me confirme qu'il s'agit du atikmpag.sys. Je le passe en .old, je redémarre, rien de nouveau.
Je mets mon pilote à jour à l'aide de Driverbooster, rien de nouveau.
Je télécharge le nouveau logiciel radeon software, rien de nouveau.
Je mets W10 à jour, rien de nouveau.
Maintenant ce n'est plus atikmpag.sys qui me pose problème mais amdkmdag.sys.
Existe-t-il une solution du type, effacer TOUS les pilotes commençant par "ati" ou "amd" pour mettre les pilotes à plat et télécharger le dernier. Je pense qu'il y a un conflit mais je ne trouve pas. Je n'y arrive plus, je tourne en rond. Je ne voudrais pas effacer n'importe quoi non plus.
D'ailleurs je ne trouve pas amdkmdag.sys même dans les fichiers cachés.
Je peux utiliser l'ordinateur pour des applications simple et non gourmandes en ressources mais j'ai aussi constaté que dès que j'ouvre quelques fenêtres en plus, c'est la M***E !
J'espère avoir été clair.
MERCI POUR VOTRE AIDE !!!!!!
