I have an ASUS Notebook. Every 10-20 minutes, the screen goes black. Once you wiggle the mouse, the screen comes back, but it is not caused by lack of activity because it will happen in the middle of something I am doing. I recently purchased it, and assume it is not a hardware problem, but I turned off all of the settings that would cause it. As you can imagine this is incredibly irritating when trying to watch a movie. What is your suggestion?
