When ever I'm on the laptop, every 20 minutes or so, music or an ad or a news feed will start playing. I exit out of all the progams I'm using and it keeps playing for a good 30 seconds before it starts again. I have even logged out but it keeps going there as well. I checked the sound mixer once to see if it was anything i knew but it just say "Source Uknown".
Please help
Thank you
