Computer Crash
One of the more complicated reasons why laptop screen goes black is a crash. This could occur for a variety of reasons and is often very difficult to fix. You will have to take the machine to a computer repair shop, and they will open up the laptop there to find the cause. Needless to say, this could set you back by a few hundred dollars as well. The crash could be caused by overheating, or maybe even a loose power supply cable. One solution for you is to play an audio file if the laptop screen goes black. If it does not play at all then something is wrong with the entire system, but if the audio file plays then it is just the laptop screen that is troubled.
Virus
There are a few computer viruses that can cause this problem, but most antivirus programs can effectively deal with such a virus. Update your antivirus software regularly and make sure you download all possible firmwares, and this sort of virus will be successfully thwarted. If your machine is infected with such a virus then your video drivers will most certainly be affected, and even your video card could get contaminated. All this results in your computer screen going black, and in some instances, your laptop screen may even go blue.
Drivers and Programs
The video drivers are crucial for making the computer monitor function properly. On some occasions though, these programs can stop functioning due to some reason. If your laptop screen goes black after startup on a consistent basis, then maybe it is your video drivers that are malfunctioning. To avoid this situation, you should constantly upgrade your video drivers, and should also refrain from using pirated video drivers. Spend those extra bucks on getting licensed drivers, and you will save a lot of unnecessary expenditure in the future. Read more on how to upgrade laptop video card.
