The computer has a black screen 10 while running

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

There are several reasons why a black screen may appear on your computer:

1) The display is powered off, or the display data cable is in poor contact;

2) There is no power supply to the motherboard;

3) Poor contact or damage to the graphics card;

4) Poor CPU contact;

5) Poor contact of memory modules;

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

Black screen at boot. Phenomenon: The black screen is turned on and there is no display, and there may be an alarm sound.

Phenomenon analysis: Poor contact between hardware, or hardware failure, related hardware involves memory, graphics card, CPU, motherboard, power supply, etc. The boot of the computer must first be powered by the power supply, then guided by the motherboard's BIOS self-test, and then through the CPU, memory, graphics card, etc.

This process is reflected on the screen called self-test, first through the graphics card BIOS information, then the motherboard information, then the memory, hard disk, optical drive, etc. If something goes wrong with any of these steps, the computer won't boot up properly, or even go black.

What to do: First, make sure that the external and internal connections are connected smoothly. The external connection has a monitor, a host power supply, etc.

There is a cable between the host power supply and the host power connector inside (sometimes the contact here is not good). The more common reasons are: graphics card, memory due to long use, long-term contact with dust in the air, resulting in the oxide layer on the gold finger, resulting in poor contact.

In this regard, rub the gold finger back and forth with a moderate amount of alcohol glued to cotton, and insert it back after drying. In addition, observe whether the CPU is working normally, turn on for about half a minute, and touch the heat sink of the CPU fan with your hand to see if there is a temperature. If there is a temperature, the possibility of CPU failure can be basically ruled out.

If there is no temperature, tidy up the socket of the CPU to make sure the contact is in place. After that, before the temperature, your CPU can be upgraded: (In addition to the above method, there is also a special move:

Clear the BIOS settings by unplugging the jumper or replace the CMOS battery on the motherboard. When all of these methods have been tried and failed, you can summon Big Prawn to come out of the mountain to help.

Have you adjusted the display settings in the display not to turn off, it is recommended to go to the display options of the control panel to take a look.

Turn off the various screensavers that come with the machine, and special screensavers are easy to cause black screens.

In addition, check whether the part of the graphics card that is in contact with the motherboard is loose.

A black screen but a vibrating computer is common with hardware failures, power failures, and software issues.

When the computer boots up, if the screen doesn't show anything, but the hard drive indicator light flashes as usual, the fan is working properly, or the problem may be on the hardware. This could be caused by a faulty graphics card, memory corruption, or CPU failure. Users can inspect the cables and connectors inside the computer to make sure they are not loose or corroded.

In addition, the user can also test whether the computer is working properly on a different monitor, and if the other screen is working, then the problem may be caused by the user's original monitor.

If there is no sound or light when the computer screen goes black, there is a possibility that the power supply is malfunctioning. In this case, the user can check that the power cord is securely connected, stuffy, and that the power supply** is not overloaded, making it difficult to turn on the computer's power.

Software issues can also cause your computer to go black. For example, there was an error at startup**, the operating system or startup items accidentally caused the error, or the system files were corrupted or infected by viruses. In this case, users can try to enter safe mode, fix the problem using recovery options or application solutions, etc.

In general, a black screen but normal operation of the computer can be caused by problems with hardware and software. Users can conduct targeted troubleshooting, determine the cause of the problem, and then fix it. If the problem is more serious, you can consider a professional computer repair shop to solve it. <>

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS setup and reset the incorrect option.

1 Long 1 Short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 Long 2 Short: Wrong monitor or graphics card.

1 Long 3 Short: Keyboard controller error. Check the motherboard.

1 Long 9 Short: Motherboard flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

What kind of black screen is it? Is it back in a flash or is it always black and won't recover?

Problems with the display or graphics card; Another possibility is a memory issue; There is also a smaller possibility of medium virus.

It needs to be repaired by a professional.

It may be that the temperature is too high, depending on the reason.

What to do if the laptop suddenly goes black.

Then you will have to restart your computer, or you can press the shortcut Ctrl+Alt+Home.

Computer poisoning is usually solved by reinstalling the system, and the anti-virus is sometimes not complete.

Of course, when reinstalling the system, you need to format all partitions to ensure that there are no viruses left.

In terms of system: the corn system is relatively easy to use, not only stable, but also very smooth.

What a game. settings.

It is estimated that it is caused by overclocking the resolution and refresh rate.
