The computer boots up with a black screen, and everything on the host is normal, but it is a black s

Already tried System Restore?

The reason why the computer screen is black when you turn on but the host is normal is that the graphics card is malfunctioning, the monitor is a problem, an operating system error, and so on.

1. The graphics card is faulty.

This is one of the most common reasons. The graphics card is an important component that converts the graphics signal sent by the computer's host computer into a visible image on the screen. If the graphics card fails, the screen will go black.

This possibility can be ruled out by observing if the graphics card's cooling fan is working properly or by checking the graphics card's connection status.

2. Display problems.

The monitor may be faulty, such as a loose power cord, a poor cable connection, or damage to the monitor itself. These issues can all lead to a black screen. You can try replugging the monitor's power and signal cables to make sure they connect well.

If the problem persists, you may need to replace the display or fix it.

3. Operating system error.

Sometimes, an error in the operating system will also cause the screen to go black. This could be due to some system file corruption or driver conflicts. You can try to enter safe mode to check the integrity of your operating system and try to repair or reinstall the relevant drivers.

The precautions for turning on the computer are as follows:

1. Make sure the computer connection is stable.

Before turning on the computer, make sure that the computer's power cable, data cable, and other peripherals are securely connected. Check that the power cable is plugged in and not loose, and that the data cable is well connected to peripherals such as monitor, mouse, and keyboard. If you have a wireless device, such as a wireless network card, make sure that the signal between it and your computer is good to avoid unstable network or interrupted connections.

2. Prepare the system CD-ROM or USB flash drive.

Before booting up, it is best to prepare a system CD or USB flash drive in advance in case the system fails or the system needs to be reinstalled. When the computer encounters system problems when the computer is disbanded, it can be repaired or reinstalled with the help of a system CD or USB flash drive. This preparation can help you save time and keep your system in optimal condition.

At the same time, it is necessary to ensure that the disc or USB flash drive is clean and free of scratches, so as not to affect the operation process.

Summary. If you can enter safe mode normally, in that mode, delete the software or driver that caused the computer to go black, and then restart the computer to give it a try.
