Hello.. I have ASUS laptop. Model name is ASUS K42JA-VX032D. I am using windows 7 ultimate 64 bit. Sometimes, when I see a movie then my laptop restarts. This happen 7 to 8 times in this week. And one more thing that if I play a movie in VLC player and I raise the volume then after some time system is crash. It shows me the blue screen "Fatel exception error" . May be it's called the 'blue screen of death'. What should I do with these problems. please suggest.
