Hi I have a query regarding my Toshiba Satellite A500 OS: Windows 7 premium Processor: Intel core i5 Ram: 6 G Recently whenever I try to play a music/movie file I will often get distorted sounds. Sometimes the files play better and at other times it seems like the ram breaks down . Also I noticed that the movie files seem to 'lag' whenever the sound got distorted. Initally I thought that the speakers were at fault so I plugged in some earphones but I still heard the same distorted sounds. This problem also extends to when I am playing games and generally whenever a sound needs to be played. Furthermore i noticed that when i turn off the internet connection the sound is perfect What's going on? ( I have virus/spyware scanned my pc, defragged and even gone as far as to format and reinstall everything, but the problem still exists. Furthermore, i noticed that the problem fixes when I close the internet connection... Any suggestions would be greatly appreciated.
