The computer often freezes, sometimes with a black screen, what s going on?

Black screen fault analysis ideas and solutions 1. Black screen failure caused by computer host failure Black screen failure caused by computer host failure can be mainly divided into the following categories: 1Failures caused by the host power supply 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 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 accessories Poor or damaged computer accessories are the main causes of black screen failures in monitors. 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 incorrect or loose connection between the memory, graphics card, etc., and the motherboard, resulting in poor contact, 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 failure caused by overclocking Overclocking 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 for black screen Others such as incorrect CMOS settings on the motherboard and incorrect BIOS jumpers on the motherboard can cause a black screen failure, in which case you can change the settings according to the motherboard 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.

When you encounter this kind of failure, you may wish to think more carefully, consider the causes of the failure, and solve the failure, know yourself and the other, and get twice the result with half the effort.

The computer has a virus. Install anti-virus software.

The black screen of computer freeze can be caused by the following reasons:

1. Poor heat dissipation: This is a problem that many people will encounter, generally caused by the CPU or monitor, which will cause the computer to suddenly go black during use, and the computer will not be able to start normally no matter what, and the computer is particularly hot. The CPU is the hardest hit area in computer heat dissipation.

If it is caused by this reason, it is recommended that you can disassemble the computer for dust removal, and if you have strong hands-on ability, you can replace the fan and thermal grease.

2. Memory module failure: generally caused by loose memory module, or the memory chip itself has a problem, or it may be caused by insufficient memory capacity, if the memory capacity is not enough, the memory should be added, or replaced with a larger memory module, we should eliminate the cause of memory module failure according to the specific situation, if it is a problem with the memory module itself, it is recommended to replace the memory module.

3. Hard disk failure: Sometimes, after the hard disk is used for a long time, there will be aging or improper use of bad sectors, bad sectors, such hard disks are easy to have problems in the process of computer operation, resulting in computer crashes, we all know that all the data of the computer is saved in the computer hard disk, if the computer hard disk has a problem, the computer can not read any data, of course, it will cause a crash. If conditions permit, you can replace a new hard disk, if conditions do not allow, you can use special tools to repair and maintain the hard disk.

4. Move the computer position: In the process of using the computer, some relatively large vibrations will cause the internal hardware of the machine to loosen, which will lead to the computer crash caused by poor contact, it is recommended that the computer should avoid moving the computer as much as possible in the process of use, if it is necessary to move the computer, the action should be as light as possible.

5. If there is a problem with the computer system: it can be solved by reinstalling the computer operating system.

1. Viruses. 2. System files are corrupted.

3. Timing software or scheduled task software works.

4. The power supply of the chassis is insufficient, the DC output is impure, and the dynamic response is sluggish.

5. Poor thermal stability of memory, chip damage or wrong settings.

When the CPU needs to supply a large amount of power when running large-scale 3D games and other software that occupies a large number of CPU resources, the power supply is not enough and the power supply is overloaded, causing the power supply to protect and stop the output. After the power supply stops out, the load is lightened, and the power is started again. Since the time for protection to recover is very short, the performance given to us is that the host automatically restarts.

When the harmonic content in the DC output of the power supply is too large, it will lead to errors in the work of the digital circuit, and the performance is a frequent crash or restart.

CPU workloads are dynamic, and so are the current requirements, and they require dynamic responsiveness. Some poor quality power supplies have a long dynamic reaction time, which can also lead to frequent crashes or restarts.

After updating the equipment (high-end graphics card, large hard disk, **card) and adding the equipment (recorder hard disk), the power exceeds the rated output power of the original power supply, which will lead to frequent crashes or restarts.
