When the computer screen keeps black, you can try the following methods to solve the problem: 1. Check the hardware connection
1. Monitor connection: - Ensure that the monitor power is turned on and the power cord is securely connected- Check if the connection cables (such as VGA, HDMI, DP cables) between the monitor and the computer are properly plugged in and not loose or damaged. You can try replacing the connection cable or connecting it to another computer for testing.
2. Power connection: - Confirm that the power cord of the computer host is correctly connected to the power outlet and that the outlet has power- Check if the power plug is securely inserted into the host power interface.
3. Internal hardware: - Open the chassis (if possible), check if the memory module, graphics card, etc. are properly plugged in and not loose. For pluggable hardware, you can try unplugging it again to eliminate the problem of poor contact- Observe whether there are obvious signs of damage such as burning or expansion capacitors on the motherboard. 2、 Check the power supply and monitor
1. Power test: - If conditions permit, you can try replacing the power supply for testing to eliminate power faults- Check if the power socket is working properly and use other electrical devices for testing.
2. Monitor testing: - Try connecting the monitor to another computer to see if it can display normally, in order to determine if it is a problem with the monitor itself. 3、 Enter safe mode
-If the computer can enter the BIOS or UEFI interface during startup, but the screen goes black after entering the operating system, you can try entering safe mode.
-In safe mode, the system will only load necessary drivers and services, which helps to eliminate issues caused by software conflicts or virus infections.
-The method of entering safe mode varies depending on the operating system, and generally can be selected by pressing the F8 key or Shift+F8 key combination at startup. 4、 Repair system files
-In safe mode, the system's built-in repair tools can be used to repair damaged system files.
-For example, in Windows systems, the "System Restore" function can be used to restore the system to its previous state, or the "System File Inspector" (SFC/scannow) tool can be used to scan and repair damaged system files. 5、 Update driver program
-If the black screen issue is caused by a driver problem, you can try updating the driver.
-You can download and install the latest drivers by visiting the official website of the hardware manufacturer. Especially for key drivers such as graphics card drivers and sound card drivers. 6、 Using the minimum system method
-After ruling out hardware connection issues, you can try using the minimum system method to locate the problem.
-Only keep the motherboard CPU、 Basic components such as memory and graphics card, disconnect all other devices, and then try booting up.
-If the black screen still appears, it indicates that the problem may be with the basic components; If it starts normally, it indicates that the problem may be with other devices. 7、 Seeking professional assistance
-If none of the above methods can solve the problem, it may be due to more complex hardware or system issues with the computer.
-At this point, it is recommended to contact a professional computer repair service or technical support team for further diagnosis and repair.
The continuous black screen on the computer screen may be caused by various reasons, and it needs to be investigated and resolved according to the specific situation. During the processing, it is essential to pay attention to safety and follow the correct operating procedures.
