What is the matter with the display screen going black as soon as the computer is turned on

Poor contact of the graphics card will cause the problem of black screen, it is recommended to check.

Display wiring errors are common, usually because the host has installed a discrete graphics card, and the user is connected to the display interface on the motherboard when connecting the monitor, which is the case of a connection error, resulting in a black screen on the computer boot display, no signal input. The solution is simple, just reconnect the console and monitor.

Workaround and Steps:

1. First of all, check whether the two ends of the signal cable connected to the monitor and the host are loose and fall off, and if so, reinstall and fix it tightly.

2. Fix the signal cable, boot the test again, if the fault is still there, open the side cover of the computer host, and clean up the dust in the host first, especially the chip pins, CPU power supply part, and the dust in the slot.

3. Replug and unplug the memory. And wipe the gold finger part of the memory with an eraser to remove the oxide layer, rust and dirt. Reinstall the test.

4. After reinstalling the memory, if the fault persists, disconnect the power supply of the host, cut off the BIOS battery on the motherboard, and short the positive and negative pins in the battery slot for 6 seconds. Or according to the instructions, short the BIOS pins for 6 seconds to discharge (electrostatic) the motherboard, and then reinstall the battery or jump the jumper back to its original position. Power on the host again and start the test.

5. If the fault persists, remove all the power and data connections of the equipment that are not related to the start. Only the CPU, memory, graphics card, and power supply are left. Take the test.

6. Finally, the power supply and graphics card can be replaced for testing.

7. If the fault still cannot be eliminated, send it to a professional maintenance point for detailed maintenance.

Why does the computer screen go black after booting up, and how to solve it.

Revert as follows:

Tools Raw materials: lenovothink, win7.

1. The boot interface is to press F8 non-stop, directly open the advanced boot options, and then use the arrow keys to select the last correct configuration to enter, if not, enter the safe mode.

2. If the mouse arrow appears after the computer screen goes black, press Ctrl+Alt+Delete directly to open the task manager.

3. Switch it to the Process option in the open Task Manager interface to end the program.

4. Click "File" and select New Task.

5. Re-enter and click OK.

The reasons for the black screen are as follows:

1. One reason is system problems, such as incompatible computer upgrades, incompatible software installed on the computer and the system, or system file corruption, etc., which will cause the computer to start with a black screen.

2. If you encounter system problems, you can turn off the computer first, then restart, and press the F8 key continuously while starting up, and you can enter the advanced startup item.

There are several main reasons why the computer has a black screen:

1.If there is a large fault in the power supply of the computer host, the internal compatibility of the power supply is poor, and the power supply of the host is insufficient, resulting in a black screen, so it is recommended to go to the computer store to replace the computer power supply to solve the problem.

2.Problems with computer accessories, motherboard, memory, graphics card, these are all things that can cause the computer to go black.

The reason is that once you run a game with a large memory, it is easy to cause the accessories to not keep up with the running speed of the game, resulting in a black screen.

3.Problems with the internal wiring of the computer, and the poor contact of the internal wiring of the computer will also cause the phenomenon of black screen of the computer.

4.If the computer's CMOS settings are incorrect and the motherboard clears the BIOS jumper incorrectly, it can cause a black screen failure. This situation can be resolved by changing the motherboard settings.

5.The damage of the power switch circuit is also a major cause of the black screen of the computer, mainly because of the switch tube.

There are two possibilities: damage and damage to peripheral circuit components.

Hello dear <> ha, <>

My answer is <>

Please bear with me and take a look at <>

There are several reasons why the computer boots up and the display screen goes black:1The monitor or display cable is faulty.

First of all, check that the display cable is correctly inserted into the graphics card and monitor interface, and if the cable is loose, it can be replugged. If the line is normal, there may be a problem with the display or line itself, and you need to test other displays or lines to confirm. 2.

There is a problem with the graphics driver. If you have recently updated the graphics card driver, it is possible that the new driver is not compatible with the system and causes a black screen. You can enter safe mode to try to uninstall the new driver, or start the system repair option to restore the previous driver of the system.

3.There was an error in the system file. Loss or corruption of system critical files can lead to a black screen.

You can press F8 at startup to enter the boot options, select "Repair Computer" eggplant, and then go to "Advanced Options" and select "System Restore" to restore the previous system snapshot. 4.The memory module is faulty.

Faulty or incompatible memory modules may cause a black screen at the beginning of boot up, and you need to test each memory module to confirm the faulty module. If you have a spare memory module, you can replace the test. 5.

Hard drive failure. Corruption of system files or errors in the system boot record stored on the hard drive will result in a black screen at boot. You can use the recovery disk or USB flash drive to enter the repair console and run the hard disk detection repair tool to detect the hard disk problem.

6.Other hardware failures. Other hardware failures such as motherboards, CPUs, power supplies, etc., can also cause a black screen.

You need to confirm the specific hardware problem according to the light prompt of the computer. Motherboard lights can indicate CPU, memory, and other faults. 7.

The BIOS settings are incorrect. If you have recently changed the BIOS settings, it is possible that the self-test will fail due to improper settings and the screen will go black. It is possible to clear the CMOS and restore the BIOS to factory settings.

In short, to solve the problem of black screen on boot, first check the cable connections and the display. If the hardware wiring is correct, there may be a problem with the software driver, system files, or BIOS settings.

Hello, I'm glad to reply to you, the reasons and solutions for the black screen of the display screen when the computer is turned on:1Failures caused by the host power supply, damaged host power supplies, or black screen failures caused by poor host power quality are common.

For example, when you add some new equipment, the display has a black screen failure, after eliminating the quality and compatibility problems of accessories, the quality of the power supply is not good, and the lack of power is the main cause of the failure, at this time, you may also hear the horn in the machine alarm 12 consecutive sounds, replacing the high-power and high-quality power supply is the best solution to this kind of failure. In addition, some motherboards have ATX dual power connectors, and the wrong choice of jumper settings can also cause this kind of failure. 2.

Failure caused by the quality of accessoriesPoor or damaged computer accessories are the main cause of the black screen failure of the monitor. For example, problems with the motherboard (and the motherboard's BIOS), memory, graphics card, etc., may definitely cause a black screen failure. If the fault is orange, the replacement method is the fastest solution to replace the graphics card, memory, and even the motherboard and CPU.

3.The quality of the connection between the accessories, the memory, the graphics card, etc., and the motherboard are incorrectly or loosely plugged in, resulting in poor contact, which is the main cause of the black screen failure. In addition, if the graphics card is connected to the monitor, it can also cause this kind of failure, up to the AT power plug in incorrectly, or even if your hard disk or optical drive data cable is reversed, it may also cause a black screen failure.

4.Black screen failures caused by overclockingOverclocking or overclocking parts that are not suitable for overclocking will not only cause black screen failures, but also damage to accessories in severe cases. In addition, excessive overclocking or poor heat dissipation after overclocking to parts that are not suitable for overclocking, or damage to the cooling fan during normal use, not rotating at all, etc., will cause the system to protect itself and crash with a black screen.

5.Other reasons such as incorrect CMOS settings on the motherboard and incorrect removal of the BIOS jumper on the motherboard can cause a black screen failure, in which case you can change the settings according to the motherboard's instructions. In addition, software conflicts, such as driver problems, improper installation, improper DIY, such as incorrect BIOS flashing, incorrect power management settings, hardware damage caused by malignant viruses (such as CIH), etc., may cause the appearance of black screen failures on the display.

I hope it will be helpful to you, and you can always find the teacher if you have any other questions in the future. I wish you all the best in your life.
