What is the reason why the monitor is prone to black screen?

It is usually caused by poor contact between the memory module and the motherboard.

There may be several reasons for the black screen of the monitor:1Power issues:

The power cord plug of the monitor is not plugged in properly or the power cord is broken, resulting in the failure to supply power. 2.Graphics card issues:

The graphics card connected to the monitor is faulty, resulting in the inability to output an image signal. 3.Cable Issues:

The data cable connected to the monitor is not plugged in properly or the data cable is broken, resulting in the inability to transmit the image signal. 4.Problems with the display itself:

The display of the land indicator itself is faulty, resulting in the inability to display the image properly. 5.The operation system is a problem with the early accompaniment system:

The operating system is faulty, resulting in the failure to output the image signal properly. The above are only some possible causes, and the specific causes need to be investigated according to the specific situation.

Causes

1. If the graphics card is loose, unplugging the graphics card and reinserting it after shutting down usually solves the problem.

2. The system is overheating, including the CPU temperature is too high and the graphics card chip temperature is too high. You can install cooling fans in the appropriate locations in the case, or place the case in a well-ventilated area.

3. There is a problem with the plug of the monitor cable. The plug position should be adjusted.

MaintenanceThe protection of the monitor should pay attention to the following points:

1) Prevent unstable current.

2) Prevent interference from other electrical appliances on the display.

3) Wipe the screen of the monitor correctly when cleaning, do not spray the liquid directly on the screen, you can wipe it with a soft cloth.

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.
