Hi I have recently upgraded my operating system from windows XP to windows7. Before installing the windows 7 I took back up for all my music files and then moved all the files again. Actually I am not able to play a single music file, the thing here is that when I play any music then my system freezes and nothing happens. The only option remains in front of me is to restart the system. I don’t know what is wrong with it and why I am not able to play the music files in windows 7. Please help me in this case and also let me know why this problem is occurred.
