Bonjour à tous,
 
Voilà mon PC freeze de manière aléatoire et je n'arrive pas à decrypter le sens de la prose écrite dans /var/log/messages. J'ai l'impression qu'il est question de mémoire et de mon modem bewan adsl. Merci de vos lumières !
 
Désolé pour l'indigestion mais je sais qu'il n'y a que ça de vrai pour débrouiller ce pb....

Mdk 9.0 + modem bewan adsl pci + amd 900 + composants divers, fonctionnement sous black box, freeze au moment du retour de veille écran

Surement un pb mémoire en effet...t'as essayé un autre WM ?
 
T'utilises quoi pour ta veille écran ? (Xscreensaver, Xlock,...)

Pour la veille je pense que c'est xscreensaver, je dis je pense car jamais paramétré autrement que via kde or j'utilise blackbox. Je vais vérifier mes barrettes mémoire, merci du conseil !  

Petit cd bien pratique pour le faire : http://www.ultimatebootcd.com/
