Bonjour,  
 
alors voila le matin quand je demarre mon pc, je dois m y prendre a plusieur fois avant que windows se lance.  
je m explique :  
 
1er lancement le pc s allume mais rien n apparait a l ecran.  
2eme lancement (en appuyant sur reset) le pc redemarre et reste bloquer au lancement du bios.  
3eme lancement (toujours reset) le pc se relance et cette fois-ci windows se lance correctement.  
 
je precise qu a part ce probleme de demarrage mon pc n a aucun probleme de fonctionnement.  
 
voici l analyse de mon pc :

Merci d avance pour vos reponses.Configuration: Windows XP

Si ca bloque avant windows, ce log ne sert a rien.. Il bloque où au deuxieme démarrage? à la detection des periphériques ?

et tu as fait un redemmarage depuis
