Bonjour

Après une utilisation variable dans le temps (10 minutes ou 1 heure), mon écran ou mon pc,s'éteint. Il se rallume quelques instants plus tard (1 ou 2 secondes) et mon système redémarre.Ma carte graphique est NVIDIA Gforce 7500 LE.D'après certains forum,ce problème pourrait venir de la carte graphique.Hier n'a été fait sur mon pc et aucun changement de pilote. Je suis très novice en informatique plutôt nul.Avez-vous une idée des raisons?
Merci pour votre aide
