Averatec 5200 Black Screen

I've had my laptop for a while, over the course of the last month it would make beeping sounds and shut down automatically occassionally(maybe once every 4-5 days). Today i tried to turn on my laptop and the little led light shows that the screen is turned on and hd activity but there is only a black screen, I would sit there thinking maybe my screen may have blown or something, but it seems as if windows dosen't load(i tried to hook up my mouse and check to see if the light turns on which happens whenever windows boots up). Any ideas? Any help is appreciated thanks.
