bonjour,

depuis quelques temps, l'image se fige mais sans écran bleu lors d'utilisation normale sur le net par exemple donc reset et au reboot j'ai droit à un bip long et trois courts donc reset et idem 2 à 3 fois d'affilée puis il redémarre normalement comme si de rien n'était.
j'ai également fait un nettoyage poussière au cas où et vérifier les connexions.

ma config est la suivante
CM Asus P6T SE + proc i7 920
Carte vidéo MSI N275GTX (MS-V177)
15 go de ram Corsair XMS DDR3-1333
alim corsair HX 650 w

mon bios est à jour ainsi que mes drivers Nvidia.

votre aide me serait très précieuse car cela fait déjà quelques semaines que ça dure.

merci d'avance

je copie également le rapport de Who crashed pour les derniers événements.
