On my work computer, running windows 7. Dell. I use dual monitors. All of a sudden one screen went black. The second screen remained on but I couldn't restart the computer b/c the start button was on the other screen so I just held the power button down to shut it down. Now when I power it up, the windows 7 screen starts but then both screens go black? When I boot in safe mode by clicking F8 then both monitors work. What is the solution to get it back to normal. It's only a few months old.
Thanks in advance for help!
