My computer is often turned on soon or in the process of use, the screen suddenly goes black, and then shows no signal input, and there is no unsafe thing to kill virus. Now let me tell you about the solution of computer no signal input. I hope it will be helpful to you!
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!
