So originally, this is the problem that prompted me to find some help and then I found this site.
I downloaded this program called Super Anti-Spyware to check all the folders for any suspicious files (found none). I uninstalled some old PC games, something called "Wild Tangent", and "MyHPGames". Now, none of the music works for my media player (basic program installed in the computer I'm afraid. Don't know where to look for better programs) and the sound for my computer doesn't work at all. I'll hit mute and the air-y sound disappears, so I know it's not the speakers or the headphones.
First, how did I mess up the sound and music files without uninstalling the players or messing with any of that software?
More importantly, how do I fix the music and the sound without going back to factory restore or a restore point made three years ago?
