Are sure to do anything like move the mouse, at this point? Or does this cause you to have to force shutdown? I have a similar issue with an HP model, as well. It will randomly happen and then I can't do anything, not even move the mouse. Sometimes the speakers will even freak out. I have to just force shutdown and start back up again. :P
Enough with my rant, it may be a GPU issue, if this has always happened since the day you got the laptop. It could be a driver issue if this happened only after your installation, if could be a missing or obstructed driver. You can always use Google to get drivers, for that matter. You could always look to calling support, as well.
