It started when i clean installed windows due to a crash.. but i then reinstalled it twice to try and make my samsung yp-z5 work.. i then sent it to samsung thinking it was a possible hardware problem.. it might have been the windows media player 11 i installed. then uninstalled... then later realized that i hadnt' fully uninstalled it.. but since i don't have the player i can't test it.. if you run itunes or rhapsody and installed zune or wmp11 software.. go to add or remove programs uninstall which ever one you have.. then go back to add or remove programs and look for windows media player 11 runtime.. remove that... if you haven't installed those.. well.. idk
