Perhaps, quite often, users of personal computers have observed such a picture when a black screen appears on the screen when a personal computer is turned on.
Why does the screen go dark?
Of course, the appearance of a black screen on a computer monitor does not mean anything good. We can say with confidence that the personal computer contains errors of a certain kind, which cause such a screen. Many, after the appearance of such a malfunction, rush to reinstall their operating system, believing that this will help them in solving the problem. It should be noted that it can be solved much faster and without reinstalling the OS. First, you need to check the hard drive for various kinds of errors and then restore the Windows system until such a problem occurs.
Solution to the problem
For example, quite often a black screen appears when an incorrect shutdown of the computer is carried out. Naturally, this is accompanied by the appearance of various kinds of errors and a black screen appears. In addition, various failures in the hard disk may occur, as a result of which some system files are damaged or deleted, after which a black screen appears.
First, the user needs to check the performance of the monitor itself. This is done as follows: disconnect the monitor cable that goes from it to the computer, and turn on the power of the monitor itself. If in this case the inscription No Sigmal appears, then the monitor is in order and working as it should. After that, it is advisable to connect the same monitor to another computer and check again, because it is possible that the problem lies in some components.
If the monitor screen darkens gradually when working with the device, then this may occur due to: breakage of the loop, malfunction in the matrix, as well as in the event of a video card failure. If the computer screen darkens as you move around the screen, then most likely the problem lies in the settings of the monitor itself. For example, for the most part, this is due to the high resolution of the screen, which is not suitable for your monitor. If this is the case, then right-click on the desktop and select "Screen Resolution" from the menu. Here you can move the slider down and check how the screen will work with a different resolution. Sometimes the problem can be related to the drivers. To do this, just go to the official website of the video card manufacturer, find the right ones for your device, download them, and then reinstall them.
