Problème: IRQL_NOT_Less_Or_EQUAL

Bonjour,

je n'arrive pas à trouvé la source du problème ... j'ai installé le Logiciel Crystaldiskinfo, RAS mes deux disque fonctionne correctement, j'ai reset windows ... toujours le même problème
j'ai fais un Diagnostic mémoire idem... RAS, j'ai installé le Logiciel WhoCrashed voilà les résulta: Crash dumps are enabled on your computer.
