What is the reason for the frequent black screen of the computer?

I don't know if the black screen you are talking about is not bootable or is it easy to black screen in the operating system? If you can't turn it on, the easiest way is to buy a computer fault diagnosis card (not expensive, 15 yuan, buy one to use), use the diagnostic card to see what letters it runs, if it stops at C1-C6 or D3-D6, it is a memory problem; If it stops at 26 or ff or 7f, it's a problem with the graphics card. This way you can clearly see what is the problem.

The solution is to clean the slots (with a thin cotton swab dipped in nothing) and gold fingers (with a rubber sassafras). The computer has a black screen when it is in use, could it be the reason for the looseness? Does it come loose on its own during use?

Based on the above thinking, I think your computer is not a problem of bad contact, but a serious problem. Please check the heat dissipation of the CPU and graphics card first, many black screen failures are due to this reason. The solution is to change the fan and strengthen the heat dissipation!

If the problem cannot be solved, it is recommended that you send it for repair!

The graphics card may also be a power supply.

Erase the golden parts of the graphics card and memory sticks with an eraser...

When I came, I said two words: I want to say everything upstairs to say hehe.

Some graphics cards are not independent, they have to occupy memory, the memory is gone, the graphics card cannot be used, there are many reasons for loose memory, in short, it is easy to loosen. But it's generally fine if you don't vibrate the computer or anything.

The above questions are all possible, so I won't say more! Supplement 1 point, you see if your power supply is grounded, too much static electricity will cause computer instability, frequent abnormal failures, such as graphics cards, memory is more likely to be damaged!

There is also 1 possibility, the power supply is insufficient, if you do some operations to occupy resources, because the power supply cannot keep up, resulting in the power failure of some components in the protection state!

It will stop working, and of course the screen will go black.

Goldfinger oxidation is treated with an eraser.

It is possible that the motherboard is not of good quality and the slot is easy to loosen

Summary. Dear, hello, I'm glad to answer for you what is the reason for the frequent black screen of the computer There are many reasons, hardware configuration is incompatible, software failure, the general reason is the operating system at most, it is recommended that you reinstall the operating system once, and then the whole disk is antivirus, first solve the software problem, if there is no problem with the software, it is the hardware.

Pro-Gao Brigade, hello, I'm glad to answer for you what is the reason for the frequent black screen of the computer, there are many reasons, the hardware configuration is incompatible, software failure, the general reason is the operating system at most, it is recommended that you reinstall the operating system once, and then the whole antivirus, first solve the software problem, if there is no problem with the soft hole call, that is the hardware.

How to reinstall the operating system again.

The computer reinstallation system is generally divided into two types: standard original system installation and third-party image installation. The first kind of installation is to use the system installation disc provided by the manufacturer or to the installation part specified by the manufacturer, run the installation file in the installation disc or the installation part of the installation of the **, generally, according to the installation process prompts step by step. This method is the most original installation, which takes a long time, but the effect is better, and there are generally no compatibility problems.

The second kind of installation, is to the third party on the Internet to make a good system image file, put it in the boot U disk or Qiaobi CD, and automatically install the system to the computer hard disk directly by the image installer after starting, this method does not require much user intervention, the speed is fast, but it is prone to drive compatibility problems. The computer can be reinstalled through the disadvantage of the U disk mode and the hard disk mode, because there are few disc modes now, unless you use the original disk, generally the U disk if you install it yourself, you can ** system files, and then prepare an empty U disk, and then use the software to make a startup disk, put the ** system files in, you follow the prompts to install it. There are many ways to reinstall the computer system, which are often used by maintenance personnel, one is the method of starting the virtual disk of PE in the PE system, first of all, the important data on your computer is backed up, and then it is good to be unattended.

It takes about 40 minutes to reinstall a system, and the method of using the disc is only to boot from the disc when booting, everything else is the same.

1. Failure caused by the power supply of the host. Black screen failures caused by a damaged host power supply or 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 dual power connectors, and their selection of jumper settings can also cause this kind of failure.

2. Failure caused by the quality of old cracked parts. Poor quality or damage to computer accessories is the main cause of black screen failure of the monitor. For example, problems with the motherboard (and the motherboard's BIOS), memory, graphics card, etc., may definitely cause the occurrence of 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 connection quality between the accessories. The main cause of black screen failure is the incorrect or loose connection between the memory, graphics card, etc., and the motherboard. Moreover, if there is a problem with the connection between the graphics card and the monitor, it may also cause this kind of failure, until the AT power supply is plugged into the silver hole incorrectly, and even if your hard disk or optical drive data cable is reversed, it may also cause a black screen failure.

Computer black screen: The computer malfunctions and causes the display to be abnormal.

Hello, please analyze and solve it from the following aspects.

1 Computer poisoning or malware may also cause computer abnormalities, the solution is to upgrade the anti-virus software, anti-virus, if it really doesn't work, reinstall or restore the system. Reinstalling or restoring the system can completely resolve the software side of the problem.

2. Unreasonable configuration, uncoordinated, and incorrect BIOS settings will also cause computer abnormalities, so you should find more professional personnel to solve the problem when installing or upgrading hardware. You can send the configuration down to help you see if the configuration is reasonable.

3 The high temperature of the computer will also cause the computer to be abnormal, it is recommended to use Master Lu software to measure the temperature of the hardware, and then solve it.

4. Due to the voltage instability point, the power supply is not enough, and it will often cause computer abnormalities, if it is caused by these reasons, configure a voltage regulator, and replace the high-power power supply to solve the problem.

5 Caused by running large software and programs, such as playing big games, using large software, watching Blu-ray movies, etc., it should be caused by poor computer hardware configuration. The only solution is to upgrade the computer configuration and optimize the computer system.

6 Old computer Because there is too much dust in the case, it is easy to cause computer abnormalities caused by short circuits. Clean the inside of the chassis frequently.

7 Old computer Due to the long period of use, the capacitance of the motherboard circuit is aging, which will also cause abnormal problems in the computer. Only sent for repair or replacement.

8 Old computer hard disk will also fail after a long time, causing the computer to crash, which requires the use of hard disk testing software to test the hard disk, repartitioning the installation system can repair the hard disk logical bad sectors, can not be repaired, and only to replace the hard disk.

If it helps, please choose the answer you are satisfied with!!

There are many system problems. It is also possible to have a memory module. It is recommended that you unplug the memory module with an eraser. Sassafras metal strip position!
