I am facing a very peculiar problem: Sometimes the sound of my computer vanishes, and sometimes it is perfectly fine. I can ply songs for hours but sometimes the song stops in the middle and I have to restart windows to resume the playback. Lately this problem has increased tremendously, as every now and then I find my computer without any sound. I tried formatting the pc and installing all drivers provided in the cd provided. But nothing seems to work. I work on win 98se.My sound is on board. Please help me!
