When a Win10 computer shows a black screen with only one mouse pointer left, it may be caused by various reasons, including graphics card driver issues, system file corruption, malware infections, hardware conflicts, or connection problems. Here are some steps and methods to solve the problem: 1. Check the hardware connection
1. Monitor connection: - Ensure that the connection cables (such as HDMI and VGA cables) between the monitor and the host are securely connected and not loose or damaged- If it is a laptop, make sure the external monitor (if any) is also connected correctly.
2. Power and battery: - Check if the power cord is plugged in properly and if the power outlet has power- Laptop users also need to ensure that the battery is fully charged or connected to a power adapter. 2、 Restart the computer and enter safe mode
1. Restart the computer: - Press the power button, wait for the Windows icon to appear, and long press the power button to force a shutdown- Repeat this operation about three times, and the system will automatically enter the "Troubleshooting" interface.
2. Enter safe mode: - In the "Troubleshooting" interface, select "Advanced Options", "Startup Settings", and "Restart" in sequence- After restarting, press F4 or other prompted keys to enter safe mode. 3、 Repair or update driver programs
1. Graphics card driver: - In safe mode, open Device Manager (which can be accessed by pressing the Win+X keys and selecting "Device Manager")- Expand "Display Adapter", right-click on the graphics card driver, and select "Uninstall Device"- After uninstalling and restarting the computer, the system may automatically install new drivers, or you can download and install the latest drivers from the official graphics card website.
2. Other hardware drivers: - If the problem persists, you can consider checking and updating the drivers for other related hardware, such as sound cards, network cards, etc. 4、 Use system repair tools
1. System File Inspector (SFC):- In safe mode, open the command prompt (administrator)- Enter the 'sfc/scannow' command and press enter to execute. The system file checker will scan and repair damaged system files.
2. System restore: - If the above methods are ineffective, you can try using the system restore function. In safe mode, open the "Control Panel", select "System and Security" ->"System" ->"System Protection" ->"System Restore"- Select the nearest restore point and follow the prompts to perform a system restore. 5、 Kill malicious software
-In safe mode, run antivirus software to conduct a comprehensive scan of the system, searching for and removing malicious software. 6、 Reinstall the system
-If none of the above methods can solve the problem, it may be necessary to consider reinstalling the Windows 10 system- After backing up important data, reinstall the system using Windows 10 installation media (such as a USB drive)- Insert the installation media, restart the computer, press F12 (or other prompted key) to select boot from USB drive, and then follow the prompts to reinstall the system. 7、 Precautions
-Before performing any repair operations, please ensure that important data has been backed up to prevent data loss.
-Regularly update the Windows 10 system and software to fix known vulnerabilities and errors, and improve system stability.
-Avoid using pirated software and software from unknown sources to reduce the risk of malicious software attacks on the system.
