Here's my issue : I have a new computer with Windows 7. My Internet connection is usually fast, but when I play music or videos, it becomes suddenly incredibly slow. It can take several minutes to load a basic web page like Google. If I pause the music/video and refresh the page, it loads in less than a second. - The problem doesn't seem to come from my browser because I've tried with other browsers like Firefox and IE8 with no add-ons and it was still slow. It also affects other programs that use Internet (e.g. Vuze). - The problem doesn't seem to be my Internet connection because I have a second computer that runs with XP and the connection is always good. - The problem doesn't seem to be the media player because I tried with WMP12, Real Player and GOM player. - It might be a speaker issue because I don't experience this problem when the sound comes out of my headphones. It only happens when the sound comes out of my "Wireless Music System for PC" from Logitech. (this is a Bluetooth device). Can anybody help me to fix that?
