I have a hewlett-packard pavilion, CPU is AuthenticAMD AMD Athlon(tm), window Me. Recently my little brother was playing a mini flash game and it got frozen, and after I reboot the window the sound is gone, at the device manager the sound device is disappeared; it didn't open anything when i clicked on the volumn control, and it doesnt let me select any options of sound of any programs like soundrecorder or mic; n the win media player said there is no sound device installed or the device might be used by another program when i tried to play a song. Please help me out, Thanks so much!
