Bonjour,
Pendant que je joué, W11 s'est arrêté sans aucun message d'anomalie. J'ai redémarré W11 sans problème. Dans le journal des évènements, j'ai un message d'anomalie qui correspond à l'heure du plantage :
 
'ModernDeployment-Diagnostics-Provider'  
 
Sur les forums je ne trouve aucune information.
Par avance, merci pour votre aide.
 
Voici ma configuration :
 
Windows 11  64 bits
Processeur : RYZEN 7 5800X
16 GO de mémoire vive : DDR4 3200 MHz
Carte graphique : Sapphire R9 290 TRI-X OC UEFI
Carte mère : MSI X570S CARBON MAX WIFI
1 SSD M2 Crucial NVME 500 Go pour le système  
1 SSD de 250 GO réservé pour une application
1 disque dur 3 TO pour les données
1 graveur Blu-ray ASUS
alimentation ANTEC HCG650 GOLD
refroidissement : CORSAIR H60I PRO XT
 
 

Ce n'est pas suffisant pour diagnostiquer.
Il faut regarder tout ce qu'il s'est passé avant l'événement kernel-power.
 
Regarde aussi si ce n'est pas un BSOD avec le logiciel Whocrashed.

Bonjour et merci ,pour votre réponse.
Ci-dessous le résultat du logiciel Whocrashed. Si je comprends le 'report', il s'agis d'un problème hardware. Reste à identifier le composant. Tous les composants sont neufs sauf la GPU qui a plus de 10 ans et l'alimentation qui a 2 ans.
