Ok I really have no idea what happened but for some odd reason, I couldn't hear any audio from my computer. I mean, its been fine for 2 years but now, there is no audio coming out. I have an HD Realtek audio and whenever I try to troubleshoot it, it says the audio is perfectly working but I couldn't hear any sounds though. Plus, my winamp won't open now!!!!!!! I was just using it a moment ago and when I restarted my comp, I could no longer open my winamp and it keeps on saying this: I already checked the sound and audio devices 5 times now and I couldn't see any errors that can kindle the audio problems... @#$! I need help guys...
Uninstall and reinstall the sound card drivers. If that doesn't do the trick then your soundcard is probably malfunctioning or windows as a whole is malfunctioning.
