The following are some solutions: Check the power supply: completely power off the computer, wait a few minutes and then turn it on again. If the computer starts normally, then a power supply failure is suspected. You can try to replace the power supply or check the power supply connection. Troubleshoot hardware: If the power supply is OK, the problem may be hardware.
First check whether the external wiring of the computer is connected properly, and re-plug each connection to see if the fault is eliminated.
Restart now. When the computer is turned on and the host power is turned on, the power light is on but the monitor is black. After the computer is turned on, the screen is black and there is no display or a prompt similar to no signal.
There are many solutions to the problem of a black screen with no signal when the desktop computer is turned on, such as checking the video cable, checking whether the independent graphics card is loose, checking the memory stick, checking the cooling fan, checking the power supply, checking signal transmission problems, etc.
You can try to replace the power supply, or check the power supply connection. Troubleshoot hardware: If the power supply is OK, the problem may be hardware. You can try to re-plug and unplug hardware devices, such as hard drives, memory modules, graphics cards, etc., to ensure that their connections are correct and tight.
Restart now. When the computer is turned on and the host power is turned on, the power light is on but the monitor is black. After the computer is turned on, the screen is black and there is no display or a prompt similar to no signal.
Make sure all cables are connected correctly Sometimes the black screen problem on desktop computers is caused by incorrectly plugged cables. Therefore, you should first make sure that all cables are in the correct jacks. Includes power cord, display cord, and all other wires. Always unplug the computer and monitor before doing any work.
Solution to black screen when computer starts: Check whether computer components are inserted securely. First, check whether the monitor cable is securely and reliably inserted into the host interface, and then check whether the contact between the graphics card and the motherboard IO slot is good.
The main reasons why the computer has a black screen without signal are as follows: Check whether the connecting cable between the monitor and the computer is tightly installed. It is recommended to re-plug the connecting data cable or replace the data cable.
1. Restart immediately. When the computer is turned on and the host power is turned on, the power light is on but the monitor is black. After the computer is turned on, the screen is black and there is no display or a prompt similar to no signal.
2. Solution to a black screen when the computer starts: Check whether the computer components are inserted securely. First, check whether the monitor cable is firmly and reliably inserted into the host interface, and then check whether the contact between the graphics card and the motherboard IO slot is good.
3. Make sure all cables are connected correctly. Sometimes the black screen problem on desktop computers is caused by incorrect cable insertion. Therefore, you should first make sure that all cables are in the correct jacks. Includes power cord, display cord, and all other wires. Always unplug the computer and monitor before doing any work.
4. Solution to a black screen when the computer starts: Check whether the computer components are inserted securely. First, check whether the monitor cable is firmly and reliably inserted into the host interface, and then check whether the contact between the graphics card and the motherboard IO slot is good. First, check whether the display signal cable and host interface of the computer host are loose.
1. It may be that the monitor and the host video cable are connected incorrectly or the video cable is loose. The computer monitor has a black screen with no signal and no signal input.
2. Generally, the following situations often lead to a black screen after the computer is turned on: There is a problem with the monitor, or there is a problem with the connection cable between the monitor and the host. There is a problem with the memory or poor contact. There is static electricity on the motherboard, causing it to become unresponsive. The discrete graphics card has poor contact or a problem. The motherboard is broken or has a problem.
3. The host power supply is damaged or the host power supply quality is poor, which often causes our black screen failure.
4. Generally, the following situations often lead to a black screen after the computer is turned on: There is a problem with the monitor, or there is a problem with the connection cable between the monitor and the host.
5. The screen of the desktop computer suddenly goes black. First, determine whether it is a software problem or a hardware problem. The method is very simple, which is to redo the system. If the situation improves, it means there is a system problem. Otherwise, check the hardware. When troubleshooting hardware, the focus is to start with the simplest and easiest things to do, such as dust and heat dissipation.
1. Restart immediately. When the computer is turned on and the host power is turned on, the power light is on but the monitor is black. After the computer is turned on, the screen is black and there is no display or a prompt similar to no signal.
2. The host is normal and the display screen is black. First check the power indicator light of the display screen. If the indicator light does not light up, try plugging the power plug in again. If the indicator light is on, check whether the data transmission cable between the display and the host is loose or broken.
3. Solution to a black screen when starting the computer: Check whether the computer components are inserted securely. First, check whether the monitor cable is securely and reliably inserted into the host interface, and then check whether the contact between the graphics card and the motherboard IO slot is good.
4. Make sure all cables are connected correctly. Sometimes the black screen problem on desktop computers is caused by incorrect cable insertion. Therefore, you should first make sure that all cables are in the correct jacks. Includes power cord, display cord, and all other wires. Always unplug the computer and monitor before doing any work.
