There is no signal input during the use of the computer. Is it turned off. What's going on. Now let me tell you about the solution of computer no signal input. I hope it will be helpful to you!
Solution of no signal input in computer
The first step is to turn on the display without signal input, and preliminarily determine that the display is good. At this time, first check whether the connecting line between the display and the host is connected properly. If it is not connected properly, connect or re plug the data cable connected to the display. If possible, try another data cable.
Unscrew the chassis screws and open the chassis cover.
Press the clips on both sides to remove the memory module.
If there is no signal input when the data cable is replaced or turned on, it indicates that the failure is the problem of the host hard disk. First check the memory prone to failure. At this time, open the host chassis, take out the memory module and wipe it back with an eraser on the golden finger of the memory.
Replace the cleaned memory into the memory socket.
If there is an independent graphics card, take out the graphics card in the same way and wipe the golden finger with an eraser. Generally, the problem that the boot is not obvious is solved when it is installed back.
Summary
The above is my hard-working solution of "no signal input to the computer", which is more convenient. Hope to help you!

Computer common problems and faults
1. The computer runs too slowly
In addition to the hardware factors, the computer speed is also closely related to the system. First of all, you can insist on whether the disk space is full, especially the C disk of the computer. If it is close to the limit, you need to delete some content to get more space, so it is recommended that the application should not be installed on the C disk as far as possible. In addition, some startup items of the computer system can be reduced to achieve faster startup speed.
2. The computer network speed is too slow
If your network speed is too slow, you might as well log in to such as Speedtest Net to test the network speed. If the speed is really slow, check the router. If it is normal, you can call the broadband provider to inquire whether there is a problem with the network service. If the wired or WiFi network cannot be connected all the time, there may be a problem with the network card hardware. Try downloading and installing the latest driver first. If it still fails, there may be a hardware problem and it needs to be replaced.
3. The computer keeps restarting
The continuous restart of the computer is usually caused by two aspects. One is infected with the virus, so we can enter the safe mode to check and kill the virus. If the situation remains the same, it may be caused by poor heat dissipation of the hardware, so you can clean the computer after all the hardware has been updated normally.
4. Block pop-up advertisements
Many times, when we install software, we will accidentally install some spam plug-ins, which will slow down the computer or pop up advertisements. Through some anti-virus software, we can remove the contents of these spam plug-ins, such as 360 anti-virus software. In addition, you can also shield Trojans or phishing websites by installing such protection software, so as to provide you with a green and safe online environment and ensure the normal operation of your computer.
5. The wireless network cannot be connected
Sometimes, windows can't connect to WiFi wireless network all the time, or the display is limited all the time. We can try to solve the problem through the "troubleshooting" and "automatic detection and repair" functions in the system first. If the problem persists, check the router or PC hardware step by step.
6. Website security certificate
If the prompt "there is a problem with the security certificate of this website" appears frequently when using the browser to surf the Internet, it may be due to the incorrect setting of the system clock. Usually, the CMOS battery of the PC motherboard will keep the clock running. If it fails, you can try to replace the battery.
7. The printer does not work
In addition to ensuring that the printer driver is the latest version and has enough paper and ink, we can try to restart the printer, find the contents in the system tray, check the print queue and ensure that the "printer offline option" is not checked. We must pay attention to these detailed problems.
8. Unable to open email
Usually, if you can't open the attachment of e-mail, it is because the corresponding software, such as PDF file, is not installed on the computer. Therefore, you can install compatible software to correctly identify. In addition, e-mail attachments cannot be opened if they do not have the correct extension.
