What should I do if the screen of the computer suddenly goes black?

1。Poor heat dissipation, it is important that the CPU is well ventilated. Working too long can also lead to:

CPU heat dissipation problems are also an important cause of computer failures. 2。There is too much dust inside the case.

Please clean it in time and keep the inside dry and clean. 3。It may be that the memory module is loose, and it should be pulled out to check whether it is damaged.

Aging or improper use of hard drives is also one of the reasons. Professional software can be used to troubleshoot, and if the damage is serious, the hard disk can only be repaired or replaced. 4。

There are compatibility issues with hardware and software. 5。The memory footprint is too large, ending unnecessary programs or the memory configuration is low 6.

Viruses are planted to kill and kill software. 7。If there are too many junk files or fragmented files, it is recommended that you clean up the system junk regularly.

Optimizer is not recommended for newbies! 8。Check to see if the capacitors in your computer's motherboard have burst.

9.It's too hot in the summer! Open the case!

It can be better! 10.Set up virtual memory There is a very large data exchange file in the hard disk, which is reserved by the system for virtual memory as a temporary storage place, many applications are often used, so the system needs to often make a large amount of data access to the main memory, so the speed of accessing this file constitutes a very important factor affecting the speed of the computer!

Generally, Windows defaults to the system to manage the virtual memory, and it will automatically adjust the size of the swap file according to the needs of different programs, but such a large and small size will put an additional burden on the system and make the system run slower! For this reason, it is best to customize the minimum and maximum values of virtual memory to avoid frequent resizes. To set the virtual memory, right-click on "My Computer" and select "Properties", and in the "Performance" dialog box in the "Advanced" option, set the "Virtual Memory".

11.Reinstall the system.

I'm experiencing this with my own computer.

Do you press the numlock button and there is a response? If it is normal, rule out the problem of the display, first of all, pay attention to the problem of the power supply and motherboard. Mine is the power supply capacitor bursting.

Change the power supply, clean up the dust again, wipe off the gold finger, and reconnect the wiring. Problem solved.

However, viruses and poor heat dissipation factors are not ruled out, so first simple, boot up, check the CPU temperature, graphics card temperature, OK, look at the power supply and motherboard.

If it is not loose, it is the oxidation of the memory and graphics card, resulting in poor contact with the memory slot or graphics card slot, resulting in a black screen, the treatment method is to turn off the power, open the compartment, dial out the memory and graphics card, and wipe the memory and graphics card gold finger back and forth with an eraser at least 6 times, blow the ash, and then insert it back, and it is generally good to boot up; The problem of power supply, when the filter capacitor of the power supply is bulging and leaking, when the power supply is insufficient after starting, it will cause the power supply to start self-protection, which is naturally a black screen; If there is a problem with the connection cable between the host and the display, the data cannot be transmitted, and the screen will naturally go black; If there is a virus in the computer, there is a problem with the operating system, and a black screen will appear.

Recently, the computer has been suddenly blacking out, what to do:

Recently, the computer has been suddenly black, and the computer has not been turned on to shut down and hibernate at a time

a- After the screen goes black, touch the monitor, signal cable, etc. and recover by itself. It belongs to the poor contact somewhere in the display system link (such as the signal line interface).

b-The black screen does not recover on its own and needs to be restarted. This black screen belongs to the computer has a protective action: CPU fan speed problem or does not rotate, U thermal protection.

Important: Computer power supply aging performance: always suddenly black screen, this situation is good to update the electrolytic capacitor inside the power supply.

A few dollars to solve the problem without changing the entire power supply.

Note: Recently, the computer has been suddenly black, and it has nothing to do with the software or system.

Black screen caused by software.

1. Sometimes after installing some software or hardware drivers, you find that after restarting, the computer can't enter the system, and the screen has been black, which is the black screen of the notebook caused by the software. If the screen is blacked out due to software, take Windows as an example, you can restart the machine and press the F8 key a few more times when turning on the computer to bring up the system's boot options menu.

2. After the system boot options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode. Then restart the machine and see if the laptop can fix the black screen issue.

Hardware-induced laptop black screen.

1. On the laptop, there is a sensor switch, when the screen is closed, the display screen will automatically turn off, so as to save power consumption. Some notebooks are mechanically touched, such as when the screen is closed, it will touch it, like a beginning to disconnect the power of the display.

2. There are many reasons for the black screen caused by hardware. Let's talk about the cause of static electricity first, sometimes static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to turn off the battery and power of the laptop, and then press the power of the laptop a few more times to let the machine release the static electricity.

Then connect the power supply, turn it on, and see if it can solve the fault.

3. The memory is loose or the memory has a hardware failure.

4. The LCD screen part of the notebook is faulty. There are some notebooks that are a little older, and this may be the case.

5. The hardware failure of the graphics card, the graphics card is responsible for the source of all the display output of the computer, so it has a problem, and there is no display on the screen. If the graphics card is broken, you can't solve it yourself, and you can only find the computer's after-sales solution.

It didn't work to ask a question, only the mouse worked, and the others didn't work.
