The black screen of the computer when it is turned on and nothing is displayed, which is a more annoying problem. Such a fault situation may be a system problem or a hardware failure. Therefore, we need to troubleshoot and solve the problem step by step, so what aspects should we start to troubleshoot?
1. Check the power supply and display
Sometimes, the black screen of the computer may be caused by a problem with the power supply or monitor. You can check this by following these steps:
1. Make sure the power cord, adapter, extension cord, and socket are all properly connected and are not loose or damaged. If possible, you can test it by replacing it with a different power cord or outlet.
2. Make sure the monitor is properly connected to the computer and is not loose or damaged. If possible, you can test it out by replacing it with a different monitor or monitor cable.
3. Make sure that the power switch of the monitor has been turned on, and the brightness and contrast of the monitor have been adjusted to an appropriate degree. You can try pressing the menu key or other function keys on the monitor to adjust the settings of the monitor.
4. If your computer is a laptop, you can try pressing Fn + F5 or other key combinations to switch the display mode and see if you can display the screen on the built-in screen or external monitor.
2. Restart your computer
Sometimes, the black screen of the computer boot may be caused by an abnormality in the computer system or program. You can restart by following these steps:
1. Press and hold the power button to force the computer to shut down.
2. Wait a few seconds, then press the power button to start the computer.
3. Observe whether the computer can be turned on normally and the screen is displayed.
3. Enter safe mode
Sometimes, the black screen of the computer may be caused by compatibility or conflict issues with the computer system or drivers. You can try entering safe mode to troubleshoot and resolve the issue. Safe mode is a special boot mode that loads only the most basic systems and drivers and can help you diagnose and fix problems with your computer. You can enter safe mode by following these steps:
1. Restart the computer, and when you see the Windows logo or manufacturer logo, press the F8 key or other specified key to enter the advanced boot options menu.
2. In the Advanced Boot Options menu, use the up and down arrow keys to select "Safe Mode" or "Safe Mode + Network", and then press the Enter key to enter Safe Mode.
3. In safe mode, you can try the following:
(1) Check and update the system and drivers to make sure they are the latest versions. You can use Windows Update or Device Manager to check and update.
(2) Uninstall and reinstall the monitor drivers to make sure they are the correct version. You can use Device Manager to uninstall and reinstall.
(3) Restore the system settings and restore them to the previous normal working state. You can use System Restore or other recovery tools to do the restoration.
Restart the computer to see if it turns on properly and the screen is displayed.
Fourth, clear CMOS
Sometimes, the black screen of the computer may be caused by the wrong CMOS settings of the computer. CMOS is a chip that stores the hardware configuration information of a computer, and if the CMOS is not set correctly, it may affect the normal boot of the computer. You can try clearing the CMOS to restore your computer's default settings. You can clear CMOS by following these steps:
1. Turn off the computer and disconnect the power cord and battery.
2. Open the back cover of your computer and find the CMOS battery, which is a round, flat battery, usually located on the motherboard.
3. Carefully remove the CMOS battery, wait a few minutes, and then reinstall the CMOS battery.
4. Close the back cover of the computer and reconnect the power cord and battery.
5. Start the computer to see if it can be turned on normally and the screen will be displayed.
