There are multiple reasons for a screen going black:
A) If your computer is running low on power, it may put itself to sleep just before it shuts off. I have had this happen to my computer tons of times
B) Depending on your settings, you may have your sleep mode set really short. You can easily fix this by going into your control panel and playing with the settings you desire. The computer will go to sleep mode after however many minutes of inactivity it is set for.
C) If there are no lights flashing or anything running with the computer, it is most likely shut down. In this case, find the power button, turn it back on, and enjoy.
D) If you own a separate monitor for your computer and your computer is running, one of the wires may be loose or the monitor itself may not be turned on. Unplugging and replugging wires seems to be a good strategy.
