So i have a new laptop, and i havent installed windows 7 updates in a while. I go to install the updates and now i keep getting this buzzing sound when I listen to music whether its online, or even an audio cd. It seemed to have done it after the install. When it buzzes randomly during a song or whatever, the cursor on the mouse then goes slow for a brief second during the buzz then goes back to normal. Has anyone experienced this before? I have a Dell Inspiron. Is there some kind of corrupted file that windows had on their patch for the updates? How do I uninstall it?
