The computer suddenly stops, the black screen does not stop alarming

The graphics card is in bad contact or broken.

If there is a hardware problem, open the chassis to check whether all parts are installed properly when the power is off.

Summary. Question 1: What should I do if the computer suddenly loses power and then turns on and the screen goes black?

Answer: first soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., if you do not install drivers, patches, software, find out what is not suitable, do not install.

The computer suddenly loses power during normal operation and then starts automatically, but the display screen is black.

Question 1: What should I do if the computer suddenly loses power and then turns on and the screen goes black? A:

First soft and then hard,This macro question is caused by software conflicts、Inappropriate driver、System problems,You can restore the system in safe mode,Or collapse the book can not reinstall the operating system,Don't install software、Patches、Drivers, etc.,If you don't install drivers、Patches、Software,Don't install inappropriate things。

You've done a great job! Can you elaborate on that?

The CMOS setting of the motherboard is abnormal, this situation is not necessarily caused by man-made, the sudden power failure of the computer in operation, and the accidental heavy chain Sun Juqi may make the Bicheng CMOS setting abnormal, which is also the reason for the black screen of the computer monitor Solution: Restore the CMOS factory settings, remove the CMOS battery on the motherboard, wait for 5 minutes, and then reinstall the battery.

Summary. Hello dear <>, 1Poor heat dissipation.

Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal. 2.Memory reasons.

When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard. 3.Power issues.

The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small. 4.Software factors.

Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down.

The desktop computer suddenly stops running with a black screen, and after trying to turn on the computer again, it has repeatedly stopped running on the black screen and then automatically restarted, and it cannot be turned on.

If you feel that my answer is still satisfactory, you can click on my avatar for one-on-one consultation. Finally, I wish you good health and a good mood!

<> someone who repairs the computer looks at it and says that it detects a problem with the hard drive, is it possible? After opening it, one of the disks was missing.

It is also possible that system issues lead to disk loss.

Summary. Hello Dear Glad to answer for you There may be many reasons why the computer often goes black, and it is recommended that you try the following methods:1

Check the power supply** and power cord. After the power is off, check that your computer's power cord is not properly connected or loose, and plug it back in if there is a problem. 2.

Check if the graphics card is working properly. You can try to reseat the graphics card and clean the graphics card slot. 3.

Check the memory. Use some memory detection software to do some testing and testing on the memory to see if there is a problem with the memory. 4.

Replace the power supply. Power problems can also cause the computer to go black, so consider replacing it with a new power supply. 5.

Check your computer's cooling system. Overheating the computer can also cause a black screen, you can check the fan, radiator, heat sink, etc., if you find dust or debris, you need to clean it.

Kiss you Zisheng is good to answer for you There may be many reasons why the computer often blacks out screen, and it is recommended that you try the following methods:1Check the power supply** and power cord.

After the power is off, check that your computer's power cord is not properly connected or loose, and plug it back in if there is a problem. 2.Check if the graphics card is working properly.

You can try to reseat the old graphics card and clean the graphics card slot. 3.Check the memory.

Use some software for internal wheel memory detection to do some testing and testing on the memory to see if there is a problem with the memory. 4.Replace the power supply.

Power problems can also cause the computer to go black, so consider replacing it with a new power supply. 5.Check your computer's cooling system.

Overheating the computer can also cause a black screen, you can check the fan, radiator, heat sink, etc., if you find dust or debris, you need to clean it.

Dear, if the above methods cannot solve the problem, it is recommended that you send your computer to a professional computer repair shop for repair.

If any indicator does not respond, on the premise of ruling out the power adapter, it must be that there is a problem with the power chip of the motherboard or a problem with a short-circuit breakpoint.

If the indicator light responds to a black screen, if you say black screen is carefully shining a flashlight to see the image, this is a pseudo-black screen.

Changing the lamp tube will do the trick. If you say that the black screen is the knowledge of no image, the screen is slightly bright, and the black screen is late,This is a more typical symptom of the graphics card door chip,Need to change to a new and improved version of the chip,If the real black screen is generally the graphics card or the hole backup memory problem may be greater。

Solve the hardware failure of the notebook, and you are welcome to ask directly if you have any questions. Direct Hi Ask and User Information Deduction Kou and ** Ask are OK.

If the power supply is insufficient, or the hardware fails, you can detect your power consumption, which is to calculate the total power consumption of your hardware, and then divide it to get your overall power consumption, because the conversion efficiency of the silver spike power supply is about 80%, and then compare the rated power of your power supply to see if it is enough.

There is also a hardware failure, you can see if there are any burned, swollen capacitors on the motherboard and graphics card.

In addition, there are products on the stationmaster's group **, cheap ***.
