Thinking about it, though, it would seem more likely that one of the bridges (north bridge?)(which would mean their cooling mechs aren't doing very well in the laptop chassis) would be in its death throws because the cpu is less involved when data is transferred between components like disks, usb, and video. The cpu is only dragged into the action to start the process and monitor that it has been completed, or to handle something the component can't handle like decoding or encoding. Does that make sense or am I talking gibberish?
