Whether you're a newbie or an experienced user, this guide will take you step-by-step to fix your problem and bring your computer back to life.

1. What should I do if the screen goes black when the computer starts up?

What should I do if the screen goes black when the computer starts up the host? This is a problem that many computer users may encounter in daily use. When we press the computer power-on button and a black screen appears on the host computer, first of all, don't panic. Next, you can try to solve this problem through some methods.

Check external connections

First, we should check all external connections, including monitors, power cords, keyboards and mice, etc. Make sure they are all firmly connected and have nothing loose or broken. Sometimes a poor connection will cause the host to have a black screen. After adjusting the connection, restart the computer to see if the problem is resolved.

Check the monitor

Secondly, you can check whether the monitor is working properly. You can try connecting the monitor to another computer to see if the screen can be displayed. If the display is normal, the problem may be with the host. And if there is a problem with the monitor itself, you can consider replacing or repairing it.

Check the power supply

In addition, make sure the computer’s power supply is normal. Check that the power cord is plugged into the outlet, that the outlet itself has power, and that the power switch is on. Sometimes power problems can also cause the host to fail to start normally.

Restart the computer

If none of the above methods solve the problem, you can try to force restart the computer. Turn off the computer power, wait a few minutes and then restart the computer to see if it can display normally. Sometimes a system failure or error will cause the host to have a black screen. Restarting the computer may solve this problem.

Enter safe mode

If the screen is still black after restarting the computer, you can try to enter safe mode. Press the corresponding key combination (usually the F8 or Shift key) when the computer starts. After entering safe mode, you can try to fix system errors or restore to a previous stable state.

Check the hardware

Sometimes the black screen of the computer host may also be caused by hardware failure. Check whether the memory module, graphics card, hard disk and other hardware are faulty. You can try to re-plug and unplug these hardware or replace with other available hardware for testing.

Update drivers

In addition, outdated drivers may also cause the computer to start with a black screen. You can try to update key drivers such as the motherboard and graphics card to ensure that the system can work properly. At the same time, you can also consider upgrading the operating system to the latest version.

Clean internal dust

A computer that has been used for a long time may accumulate a large amount of dust, resulting in poor heat dissipation or poor hardware contact. Regularly cleaning the dust inside the computer, especially the radiator and fan, can effectively reduce the black screen of the host caused by heat dissipation problems.

Restore the system

If the above method still cannot solve the problem of black screen on the host, you can consider system recovery. Use a system recovery disk or recovery partition to restore the system to factory settings, which will erase all data but may resolve system failure issues.

Seek professional help

Finally, if none of the above methods can solve the problem, it is recommended to seek professional computer repair help. Professional technicians can use more professional equipment and methods to help locate and solve the cause of the black screen of the computer host.

In general, a black screen when the computer starts the host may be caused by external connection problems, monitor failure, power supply problems, system errors, hardware failures and other reasons. Users can gradually troubleshoot and solve problems according to specific situations to keep the computer running normally.

2. Why does the computer often have a black screen?

1. When in sleep or hibernation state, it is in suspended animation and will be mistaken for a black screen. Just press to turn on the computer.

2. If the computer system is damaged or has a black screen caused by poisoning, directly restart the computer and enter the BIOS interface or press F8 to see if you can enter safe mode. If you can exit the BIOS interface or enter safe mode after booting, it means the hardware is It's not broken per se, it's just a problem with the operating system. Just reinstall the operating system.

3. If the temperature of the graphics card is too high, the screen will go black. You need to shut down the computer quickly to check whether the graphics card is burned out.

3. Why does the iPad tablet have a black screen?

There are two physical buttons on the iPad tablet, one is the home screen return button located on the front, and the other is the power lock screen button located at the top of the front. When the iPad screen suddenly goes black, we can try to hold down the power button on the top for about 10 seconds to see if the screen responds.

If there is no response, try pressing and holding the power and home buttons at the same time for more than 10 seconds. See if you can force a restart. If the force restart is successful, you will see an Apple logo on the screen. After the restart is successful, you can use it normally.

If the tablet is out of power, please let it charge first and then turn it on. The Pad's battery must be charged to more than 5% before it can be turned on normally.

If the above methods are not effective, it may be a hardware failure of the Apple phone. In this case, you need to take it to an Apple after-sales service or repair shop for inspection and repair.
