Nowadays, computers are used in a wide range of areas. For example, computers can be seen in hotels, studios, homes, and schools, because they can not only help us process data in daily work, but also use computers to access information, or Perform recreational activities and more. When a computer is running, it is a very complicated process. Sometimes it is normal for the computer to have some malfunctions. For example, today we are going to talk about some solutions to the problem that the computer host is turned on but the monitor is not responding. I hope it can help everyone.
Method 1(Recommended learning:PHP video tutorial)
The reason may be The computer host power cord is not connected properly, the monitor switch is not turned on, and the monitor power supply or monitor data cable is not in good contact.
When we find that the computer does not respond when it is turned on, we need to first observe whether the computer's power indicator light is on after pressing the power button. When the power indicator light is not on, is on, then there is probably a problem with the power supply. You can check whether the power cord of the host computer is connected to the external power supply, whether there is a line fault, etc. When the computer power supply is poor, the computer will not respond when it is turned on. These require simple troubleshooting to confirm. .
When the computer indicator light is on and the CPU fan inside the computer is running normally, generally speaking, it can be initially judged that there is no major problem with the power supply. Let’s check the monitor and look at the monitor power indicator. Is the light on and the monitor data cable connected properly? At the same time, observe whether the computer keyboard and mouse indicator lights are on. Generally, if there is no problem with the host, the computer keyboard indicator light and mouse indicator light are on normally. In this case, the problem often occurs on the monitor, such as the monitor switch is not turned on. , the monitor data cable is not connected properly, or the monitor power supply is faulty, etc.
The above computer does not respond when it is turned on. If we cannot find the problem after simple troubleshooting, it is recommended to use the replacement method. If you suspect that there is a problem with the monitor, you can try it with a good one. If the problem persists, replace the data. Try changing the cable. If it still doesn't work, the problem is likely to occur on the host computer. In short, try to eliminate as much as possible. This will make it easier to find the problem. Generally, the method for troubleshooting monitors is relatively simple.
Method 2
First press the power button of the monitor. If the indicator light of the monitor does not light up, please check whether the power cord of the monitor is plugged in. good. After the indicator light of the monitor lights up normally, if the problem cannot be solved, go to the second step.
Check whether the data cable connecting the monitor and the computer host is loose, damaged or damaged. If it is not for this reason, go to the third step.
Connect another normal monitor to the host and power it on. If the monitor displays images normally, it proves that the original monitor has an internal fault and needs to be repaired. If it cannot be displayed normally, go to step four.
It may be that the graphics card and other components of the host are faulty. It is recommended to re-plug the graphics card, clean the gold finger, and check whether the fan is normal. If it cannot be solved, please find a professional to repair it.
For a computer, it has many components, such as a monitor, a host, a keyboard, a mouse, etc., and the operation of the computer and the processing of data are also very cumbersome. If here If problems occur during this period, we don’t need to be too anxious or worried. As long as we try to use some methods and techniques to solve them, there will generally be no big problems. Of course, when you usually use a computer, it would be great if you could back up some important data to prevent loss and unnecessary trouble.
