Each time you start a video call / web cam / voice call in Live Messenger, Skype, Google Talk, Yahoo Messenger, my computer freezes completely, and gives an echo. I have to manually restart. Sometimes it comes with a blue screen and restart itself. I am using Vista, and this situation existed when I had XP on this machine. What's wrong? Hardware problems? There is no virus detected after scanning the computer with Kaspersky.
