The main chassis is working, and the monitor is not responding

There may be 3 aspects to judge:

1.Graphics card issues.

Replug it in, clean the gold finger, and see if the fan is normal.

If it doesn't work again, it will be replaced free of charge during the warranty period).

2.Cable problem (replugging, checking VGA or DVI interface) 3Display issues (Check if the electrical outlet is powered on.) If it's convenient, connect it to other computers to see if it's normal).

It's not possible to restore with one click. If you don't have a system disc ready, the optical drive can be used. Start the computer and press the DEL key, set it to a disc boot in the BIOS, insert the system disk and reboot, basically complete it automatically according to the steps.

Unplug the hard disk cable, use the CPU motherboard, memory, and independent graphics card to boot the smallest system, and if it does not light up, it means that one of the three or four major parts is broken. First of all, exclude the CPU (unless overclocked and burned, it will generally not be broken), secondly, try to change the memory, then change the graphics card to see, and finally the most unlucky situation is that the motherboard is broken.

Memory,Or the graphics card is loose,,Boot does not show,Don't continue to boot.。。

Open the case. Reinsert the memory, graphics card. Turn it on again, be careful not to plug it in backwards, otherwise the consequences will be very serious...

If the memory module or graphics card is loose, take it off, wipe the gold finger, and then try to install it.

You unplug the memory, wipe off the metal bar, and plug it in.

Look at the graphics card loose by the data cables are all looking.

Then turn it on.

First, the display problem of the graphics card, resulting in continuous input signal, but the input color is black, at this time, the display is actually bright, but because the color is black, it looks similar to not turning on the monitor, it is estimated that the system is installed incorrectly, or the configuration is a little reluctant to run vista, which will cause the boot speed to be super slow and cause the situation that is stuck on the black screen.

Second, is there no thermal paste on the CPU radiator, the CPU temperature is too high, it will also cause the situation of dying when it is turned on.

Third, the display problem, the green light on the display you said is on, then it proves that the display is receiving the signal of the host graphics card, but there is no display image, most likely caused by the burning of the internal parts of the display. (Of course, for this reason, it is better to put the last test).

Suggested workaround:

1. Check whether the connection between the host and the monitor is correct.

2. Boot into safe mode (press F8 when booting up, select safe mode) to check whether the graphics card driver is installed correctly.

3. If your computer has been purchased for more than half a year, it is recommended to apply thermal paste to the radiator.

Fourth, if the first method does not work, you can reinstall the operating system, remember, you must choose the operating system reasonably according to your own hardware configuration.

The case running monitor is not responding? The solution is here!

In the process of using the computer, we sometimes encounter situations where the case is running but the monitor is not responding. This situation can be due to a number of reasons, but there are some simple ways we can fix it. This article will introduce you to some ways to solve the problem that the chassis is running and the display is not responding.

Check the power cord, power switch, and outlet.

In the event that the case running display does not respond, the first step should be to check the power cord, power switch, and outlet. Check that the power cord is plugged in tightly, make sure the power switch is on, and check that the outlet is working properly. If you notice a problem with the power cord or outlet, you should replace it immediately.

Check the graphics card If the monitor doesn't respond when the computer is turned on, and every part of the case is working properly, then you need to check the graphics card. This may be due to a dirty gold finger on the graphics card or a loose graphics card. You can take the graphics card out, gently wipe the dirt off the gold finger with an eraser or paper towel, and plug it back into the motherboard, making sure the connection is secure.

Check the memory module.

Memory modules are also one of the important factors that affect whether the display is working properly. Check whether the memory module is plugged in, if the memory module is not plugged in properly and the monitor does not respond, you can try to insert the memory module again; If a memory module is damaged, you should consider replacing it with a new one.

Check the hard drive If the hard drive fails, it will also cause the monitor to become unresponsive. You can check if the hard drive is working properly by unplugging the data and power cables on the hard drive and then plugging it back in. If the problem still does not work, you need to replace it with a new hard belt reel.

Check the motherboard If none of the above methods solve the problem, then there may be a faulty motherboard. It is recommended to take a picture of each interface on the motherboard, and then replug and replace the ports that are easy to loosen, such as power cords, graphics cards, memory modules, etc., to see if it can solve the problem. If there is still no way to solve the problem, you need to consider replacing the motherboard with a new one.

Conclusion If the case is running but the monitor is not responding, the above methods can help you troubleshoot. However, if you are not very familiar with the internal structure of the computer, it is not recommended to repair it yourself to avoid more serious failures. In this case, it is advisable to find a professional to carry out the repair.

This situation may be caused by the case not being turned on and running normally, you can replug the cable between the monitor and the case to see if it is caused by poor contact. You can also unplug the memory module and wipe it before installing itIf there is a graphics card, unplug the graphics card and wipe it and then install it to try it, there is generally no problem, if the display still does not respond after the above operations, it means that there is a hardware problem with the memory or graphics card, and it can only be repaired.

Sometimes the connection cable between the monitor and the chassis will have the problem of loose plug socket, generally due to the aging of the computer, we can replace the new power socket, and then try to reconnect, if the problem is solved after reconnection, then it is caused by poor contact, generally not much impact.

We can also try to disassemble the host and unplug the memory module to wipe, because due to the dust of the computer memory module, it may also cause poor contact, the display has no picture, it is best to unplug the graphics card and wipe it, the computer host is the most likely to accumulate dust and cause problems, so we must often clean up the inside of the host to prevent short circuits.

If the above methods do not solve the problem, then it is a hardware problem, then we need to take a special after-sales store for hardware replacement and maintenance, it is not recommended to operate it at home.
