Why does the computer screen go black and black, it will automatically recover in about two seconds.

Reinstall the graphics card driver and reinstall the system.

The original cause and solution are as follows:

1.Cause 1: The graphics card driver is faulty, and the solution is recommended to uninstall the original graphics card driver, reinstall another version of the graphics card driver, or upgrade to the latest version.

2.Reason 2: The graphics card chip is faulty, the solution: It is recommended to replace the graphics card for testing, the chip failure is not something that anyone can repair, it is recommended to send it for repair.

3.Reason 3: The display is faulty, and the solution:

The possibility of display failure is obviously the greatest,After using it for a long time,Lamp aging、High-voltage board failure will lead to the occurrence of black screen and fiber rolling,And this phenomenon will appear more and more times,General users do not have the ability to self-repair,It is recommended to ask professionals to repair。

There are several reasons why your computer monitor suddenly goes black and then resumes automatically after a few seconds:

Display Power Management: Check your monitor's power management settings. In some PC and display configurations, the display may automatically go into power-saving mode or sleep mode based on a period of non-use.

When you re-operate the mouse or press the keyboard, the monitor will snap back to itself.

Graphics driver issues: There may be issues with the graphics card driver, causing the display to go black in some cases. Try updating your graphics drivers to the latest version, or if you already do, try rolling back to a previous stable version.

Connection issues: Check that the cable between your computer and monitor is securely connected. A loose connection can tie up and cause the signal to be interrupted, resulting in a black screen on the display. Try replugging the connection cables to make sure they're connected properly.

Frequency mismatch: In some cases, your computer monitor's refresh rate and resolution settings may not be compatible with your graphics card or operating system, causing problems with your monitor. Try adjusting your monitor's refresh rate and resolution settings to make sure they're compatible with your graphics card and operating system.

Hardware failure: In some cases, there may be a fault in the display processor hardware itself, resulting in a black screen. If none of the above workarounds resolve the issue, you may need to contact the monitor manufacturer or professional technical support personnel for troubleshooting and repair.

This condition can be caused by:

1.If the power cord or ** cable of the monitor is loose or poorly contacted, resulting in interrupted signal transmission, the monitor will automatically enter sleep mode and go black, and after a period of time, the signal will be detected again, and it will automatically recover. In this case, you can check whether the power cord and ** cord are plugged in tightly.

2.The monitor's refresh rate or resolution is set incorrectly, causing the monitor to not display properly. You can check and adjust the refresh rate and resolution in your computer's display settings.

3.The graphics card driver is outdated or corrupted, causing the monitor to not display properly. You can try updating the graphics driver or reinstalling the graphics driver.

4.The display itself has hardware failures, such as aging of the electrical accompaniment, lamp failure, and so on. In this case, you need to contact the manufacturer or maintenance personnel for maintenance.

If none of the above methods can solve the problem, it is recommended to contact the manufacturer or professional maintenance personnel for testing and maintenance.

It could be due to the following reasons:

The monitor connection cable is loose or malfunctioning.

There is a problem with the monitor or graphics card driving the Hu Zhan program.

Power supply** issues or voltage instability.

The display is hard and slippery is faulty.

There are times when our computer monitor screen goes black for a few seconds and then comes back, what is going on? Let me give you a brief introduction to the reasons why the computer monitor screen goes black for a few seconds and then recovers! Hope you enjoy it!

Analysis of the reasons why the computer monitor goes black for a few seconds and then recovers:

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor graphics card contact or;

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

The machine is infected with the CIH virus, and the BIOS is refreshed destructively.

Microsoft black screen, please patch.

Secondly: First, the frequent black screen is a kind of appearance of the display, which can only indicate that the monitor itself, and the host power supply, motherboard, graphics card, BIOS settings, and software are faulty.

Second, the main reasons for the black screen are as follows:

1. The graphics card driver is not perfect enough, and it needs to be reinstalled with a stable version.

2. The power supply of the host is insufficient, resulting in insufficient power supply of the AGP graphics card, and the insufficient power may be determined by the power factor of the host power supply, or it may be caused by poor heat dissipation.

3. The onboard power of the motherboard is insufficient, resulting in insufficient power supply of the AGP graphics card.

Analysis of the reasons for the black screen of the attached computer monitor:

Circumstance. 1. The display light is not lit.

1 Check if the power is on. If the monitor light is not on, it means that the power is not on, unplug all the plugs, and plug them back in every two minutes.

Circumstance. Second, the display light is bright green.

1 If the displayed light is normal, that is, the color is bright green, but the display is black, it means that the display is broken, and the after-sales service should be called for maintenance.

Circumstance. 3. If the monitor light is yellow.

First, check whether the cable between the monitor and the host unit is plugged in.

Unplug the two cables behind the monitor and the connector connected to the main unit, plug them back in after a few minutes, and see if the connector is loose or broken when plugging in.

Check if there is a problem with the memory.

If the memory is broken, the boot will sound an alarm and replace the memory module.

Check the motherboard. If it still doesn't work, then open the case, take the motherboard down, see if there is anything on the motherboard, see if there is any smell of burning, wipe off the dust, and put it back on.

4Check the graphics card.

Check if there is a problem with the graphics card, touch the graphics card with your hand to see if it is very hot, if it is very hot, let it cool down, wipe off the dust, and then go inside.

5 Check the hard drive.
