A black screen error is often caused by a software glitch. This most frequently occurs when dealing with a program that takes over your entire screen. Typical culprits are PC games, or media players running in full-screen mode.
In these instances, the computer should otherwise appear to run well. Diagnosis should be easy to reproduce. Simply launch the program for a game or media player, and view it in full-screen mode.
Solving the problem, however, can be difficult; if the bug lies in the software, there may be no solution. You can try fixing it by running the program at a different resolution.
Also, try running the software as an administrator and, if issues still continue and the program is quite old, try enabling Windows compatibility mode.
Hope this gives you some insights.
