Many people who own computers are not necessarily proficient in computers. For example, I, as a computer nerd, often encounter some problems and feel at a loss. For example, when I use a computer, I will have a black screen, leaving only a face of my own. In fact, there are many reasons for the computer black screen. Don't worry, I'll teach you some tricks to easily handle the computer black screen.
The first situation may be because of the display. This situation is caused by the failure of the display itself, which leads to the black screen of the computer. For example, the power cord of the display is faulty, the power plug is not in good contact, the power switch is broken, and the internal circuit of the display is faulty. At this time, we need to use more computer hosts to try to eliminate the cause of the fault.
The second situation is the problem of the graphics card. The graphics card is the eye of the computer. If the computer has a black screen, remove the reason for the display. The second step is to check the graphics card. If there is no signal from the graphics card or there is a signal that cannot be sent out, the display will not light up. For this type of fault, troubleshooting is a little difficult. It is recommended to find a professional for troubleshooting.
The third is the most wordless reason, that is, the power supply. It's really hard to cry and laugh. The computer that once made up by Xiaobian suddenly has a black screen. After a long time of searching, I haven't found out what the reason is. At last, when I was discouraged, I saw that my cat had broken the power supply. At this time, I just need to change a power supply.
So the troubleshooting of the computer black screen is really unexpected from time to time. We can check all aspects of the computer black screen to see where the problem is. For example, we can deal with the problem again according to the problem, or we can refer to some books. How to deal with the computer black screen? We can avoid panic. If you can't, ask a computer technician to help you repair it.
