I really hope someone can help me with this. Its driving me crazy. For the longest time on my computer, Ive been hearing this horrible loud high pitched screeching noise coming from my speakers whenever I play Mp3's. If I continue playing music, it will happen every 20 minutes or so, and I have to restart the song/movie over. I bought new speakers, but it solved nothing. People tell me it might be something with my sound card. I have no idea what I can do to fix this, please someone help!
