The computer software has been upgraded to a black screen, and it has also been displayed once

Black Screen Workaround:

1. If the monitor is not used for a long time, the monitor will automatically turn into sleep energy-saving mode and the screen will be black.

Solution: Take win7 as an example.

1) Right-click on the blank space of the desktop and select "Personalization" in the menu to open the personalization settings dialog box.

2) Click the red box in the above picture to select "Screen Saver" to enter the screen saver settings dialog box.

3) Set the screen saver to "None". And click "Change Power Settings" to enter the power settings dialog box.

4) Click "Change Plan" to enter the change settings dialog box.

5) In the blue box selection, click the drop-down triangle, select "Never", and then "Save Changes" to exit.

After setting, the monitor will no longer automatically go black.

Second, the display failure causes a black screen.

On the internal power board of the display, the capacitance of the power supply output part is aging, leaking, bulging, and failing. When the display is first turned on, because the capacitor is not completely necrotic, in a short time, the power supply is normal, so it can be displayed normally. After working for a period of time, the power supply is seriously insufficient, causing the backlight of the LCD monitor to go out, causing the display to go black.

Solution: Send the professional display repair point for repair, and the components will be damaged even worse, and the cost will be about 30---50 yuan.

Solution: Replug, install and fix the signal cable of the monitor. If the fault persists, the signal cable can be replaced.

Fourth, the performance of the graphics card is faulty and unstable, resulting in a black screen of the display.

Solution: 1. Test after updating the graphics card driver, if the fault persists, directly replace the graphics card for testing.

Note: If you are using an integrated graphics card, you can install a discrete graphics card for testing. Or directly replace the motherboard with integrated graphics for testing.

5. The motherboard performance is faulty and the operation is unstable, resulting in a black screen of the display. Solution: Directly replace the motherboard for testing.

The system crashed, only to reinstall it.

Summary. Hello, dear, this situation is generally normal, but don't recover after the black, there is a problem!

Hello, it's an honor for me to answer your questions, it will take a little time to sort out the answers, please be patient

Hello, I'm glad to answer your questions. When the computer is updated, the black screen is good again, which is a normal phenomenon! When the screen is black, Cheng Qingkong is taking the order to update and replace,As long as it can be restored to the normal state, it's no problem.,If the screen is black all the time, it may be that there is an error in the updater"<>

There are many reasons for the black screen of your computer.

The first is,The memory and graphics card are oxidized,Caused by poor contact with the memory slot or graphics card slot,Caused by the black screen,It has a black screen probability of 80%,The processing method is to turn off the power,Turn on the compartment,Dial out the memory,And the graphics card,Align the part of the memory and the graphics card gold finger (that is, where there is a copper sheet)Wipe it back and forth with an eraser at least 6 times,Blow the ash,And then plug it back,Boot is generally OK。

The second is the problem of power supply, when the filter capacitor of the power supply bulges and leaks, when the power supply is insufficient after starting, it will cause the power supply to start self-protection, power failure, no electricity, and naturally a black screen.

The third is,There is a problem with the connection cable between the host and the display,Unable to transmit data,Naturally, the screen will be black。

Fourth, it is a virus in the computer, there is a problem with the operating system, and there will be a black screen

Are you upgrading the hardware??

There are many reasons for the failure of the computer to turn on the black screen, such as the display is damaged, the motherboard is damaged, the graphics card is damaged, the graphics card is in poor contact, the power supply is damaged, the CPU is damaged, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

1.Unplug the data cable connected to the monitor and the console, and turn on the power switch of the monitor separately. Generally, if the display is normal, it will display the manufacturer's information of the display or a prompt that the monitor is not connected, if it can be displayed normally, it indicates that the display is unlikely to be damaged.

2.Check that the exposure is good. You can check whether the contact between the graphics card and the monitor is good, whether the contact between the graphics card and the motherboard IO slot is good, and whether the contact between the memory module and the motherboard slot is good.

3.If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound.

If the memory fault is ruled out, only the CPU and the motherboard are left.

Consider that it is a problem with the system files, or that the application is not compatible with the system.

If the app is not compatible with the system, then uninstalling the app will solve the problem, and if it is a system file problem, then the system needs to be reinstalled.

If the above methods still do not solve the problem, then send it for repair.

Reinstall the system in one step.
