Merci pour ta réponse.
A défaut de passer pour un noob, je ne sais pas exactement quel driver je dois télécharger...
J'ai fait un tour sur DriverCLoud et sur le site d'AMD, mais je ne sais pas quel driver choisir (pas vu de atikmdag.sys par exemple).

Fais une analyse avec le logiciel de Touslesdrivers dans la section Mes Drivers:

https://www.touslesdrivers.com/index.php?v_page=29

Super merci, je l'ai trouvé, je le télécharge.
Une fois l'ancien driver supprimé avec DDU, ou dois-je stocker le nouveau driver et comment l'installer? Double clique dessus ? MAJ depuis le gestionnaire de périphérique ?

Je n'ai jamais utilisé de carte ATI

Il devrai en principe avoir un Setup.exe ou un Autorun.exe

Oui le fichier en téléchargement est en .exe.
Je delete donc l'ancien en Mode sans echec, et lance directement le nouveau driver en .exe
Merci pour vos réponses, j'updaterai le thread à la fin de la procédure.

Ok Merci !

Oui je suis bien administrateur du PC. Je ne suis pas sur pour l'UAC...

À tu un ou plusieurs antivirus - anti-malwares ?

Un seul anti virus --> Avira , se lance au démarrage
Un seul anti malware --> Malwarebyte, se lance manuellement
