Well sometimes after some hours of working (I can explore websites, play games or looking my photos) the screen is freezing.
I can hear the cooler is working. And when the screen is freezing, sometimes I can move my mouse, but it's not sensitive to any clicking and sometimes the mouse is freezing too. After reboot computer is working again. But it freezes each day by day.
I'm interested what's the problem. I have noticed that sometimes when it freezes, it's keyboard is very warm, because it's cooler is under the laptop. Maybe it's because of overheat? Or maybe it's Windows Vista Ultimate problem?
I don't know what to do and why it happens?
