Hi I'm new here. Nice to meet you all. I hope you can help me. 2 days ago, my computer was working fine, the monitor was fine and everything, But then my computer went to sleep and then I was unable to wake up the screen. I could hear the fan and the computer was responding, the lights, disc drive and everything would work, but my screen is black. The only way I can see anything is to hook it up to an external monitor. I thought it might be a problem with my video card driver so I updated it and still it isn't fixed.this computer is almost 4 years old if that means anything.
