screen flickers and blacks out

This question is not answered

I have a dell inspiron with intel core i5, and an intell hd graphics card.  The screen will black out for a few secounds about every 3-4 mins, i also hear a beep when it blacks out.  I updated the graphics driver, the bios, and all windows 7 updates are installed as well.  Before i did all that i noticed that when i checked my graphics settings it was on extended display and when i would change that to single display the flickering would stop however the settings would automatically change themselves back after 5-10 mins.  Any ideas?
