The computer automatically blacks out and won t start when it restarts, what s going on?

Should it be that your graphics card is overheating and there is a fan on your graphics card? How much video memory? Does the host reboot or continue to run after the black screen?

If you want to solve the problem, first find out if there is a problem, if there are other monitors, try another one, there is no problem with the display, check the temperature of the graphics card, the graphics card is no problem to see if the memory slot is plugged in tightly, and the back**connection is loose, eliminate them one by one, and the problem will be solved.

There is a problem with the graphics card.

Reasons why your computer has a black screen.

1. The quality of the memory, the memory is not plugged in properly, and the gold finger of the memory is dirty.

Treatment: Gold fingers can be cleaned with anhydrous alcohol or an eraser.

Don't plug the memory upside down.

2. The problem of the graphics card, the signal cable of the graphics card is not connected properly, and the gold finger of the graphics card is dirty.

Processing: Same as memory.

3. The display is not set properly, and the brightness.

The display can't withstand the high resolution of the graphics card.

Processing: Adjust the brightness button.

4. The power supply contact is not good.

5. Fake black screen caused by system settings.

For example: screensaver.

I think there is a problem with the ventilation of the case, which causes the CPU temperature to be too high, and it is very CPU to play farm, and it should be restarted after a few minutes after the black screen, because the temperature of the CPU has not dropped yet. It is recommended to use the next CPU detection software. For example, Master Lu, etc., the most important thing is to pay attention to the ventilation of the case, as well as clean up the dust of the case, too much dust will cause the motherboard to be in poor contact and cause a black screen.

The computer boot is done before doing it, and the screen suddenly goes black, and the boot is pure and can't be cleared.

Although the black screen after the computer is turned on, there is a probability that more than ninety percent of it is a problem with the memory module, which can be solved by a little "movement". But we can't rule out that the problem is caused by damage to the motherboard or other hardware. If you find that the computer screen is black, after trying to reinstall the VGA cable or unplugging the memory module and wiping it has no effect, the state needs to find a special computer repair shop for repair.

Cause. 1. It was controlled by a remote Trojan horse, and everything on the computer was in the hands of hackers.

2. Virus or malicious plug-in intrusion, resulting in system damage.

3. The driver installed on the computer is not compatible, and the computer will crash after running for a period of time.

4. The compatibility of the software itself, the serious conflict between the software incompatibility and the system conflict, and the computer crashes.

Common computer troubleshooting:

1. Reasons for keyboard failure:

1. If the numeric keys of the keypad are missing, it is possible that the numlock key is locked, and it can be opened through the numlock key, and this key is looping.

2. There may be a problem with the keyboard driver, you can update the driver to give it a try.

2. Solution:

1. Restart your computer. The computer will run for a long time will cause the driver to fail, if the usual fn key is good, once in a while it fails, you can restart the computer to give it a try.

The black screen after the computer starts, it may be that the system boot file is damaged or there is a virus, if you can hit the noisy number into the safe mode to restore the system in it and try to kill the virus, or enter the BIOS settings to set the first hard shot to the first loss of a boot item, it is not possible to reinstall the system to try.

The power supply is out of the air and the problem causes it to be unable to start, so it is recommended to check the power supply. If the internal circuit of the host is damaged, it is recommended to find a professional to repair it. The speed and stability of the fan are not good, resulting in poor heat dissipation, and the main cong empty machine cannot be started.

This phenomenon can also occur after the CUP is corrupted, the CPU is damaged and cannot pass the self-test, and the computer cannot boot.
