The computer monitor suddenly turned off automatically, as if the power was short, there was no resp

First rule out whether the display problem causes no display, take your monitor to other computers to try if it can be used normally, if you can't check whether the data cable is broken and internal components, if it can work normally on other computers, then you check the hardware in the host Follow-up question: Last month my monitor also had this situation, the monitor suddenly turned off, no response, and then I don't know how to get the monitor indicator light to turn on and you can use it! ：

Check the data cable when the monitor is charged! There is no signal, the display you want to turn on, you can't light it up, you have power now, you don't display, you can hear the sound of booting into the system, the host is working normally, the problem appears in the graphics card is not in poor contact, whether the data cable is damaged and the display is not normal, and the last one is the screen refresh rate is not set too high, you try to turn on the computer and press f8 until the display has a word, if there is a word, it proves that the refresh rate is too high. Follow-up:

Boot press f8 can't do it! I pressed,,The monitor indicator is not on,:The display power indicator is not on....Do you still need to ask?

There's a problem with the monitor! Even if the data cable is not plugged into the display, the power indicator should be on, is it your power plug that is not in poor contact! Try a different outlet.

Follow-up: I changed a socket and it doesn't light up! ：

If there is no power or the monitor power strip is damaged and the contact is not good, how to brighten, or take the monitor to another computer to eliminate it! If it's the same situation, it's okay to fix it.

There may be a false soldering between the memory module and the motherboard interface, or it may be a problem with the display picture tube, and there is also a loose wiring between the monitor and the computer. Please ask if your monitor indicator is on. That is, whether it is to confirm that the display can be turned on (turning on and going black are two different things).

Follow-up question: The indicator of the monitor cannot be turned on: Check whether the power cord is loosened at both ends, if not.

Try to plug it in with a good power cord, and if it turns on, it's a power cord problem. Follow-up question: Last month, my monitor also had this situation, the monitor suddenly turned off, no response, and then I didn't know how to get the monitor indicator to turn on and it can be used!

That's the display problem, take it for overhaul and see what the problem is. I haven't seen the real thing on the Internet, so I can only speculate.

You say, don't you? Follow-up: Well, is there any way to make the display light of the monitor light up?

Dude, take it and fix it

This can be due to one of the following reasons:1Power failure:

There may be a problem with the power supply that does not have enough power to keep the entire computer system running. 2.Display issues:

The monitor may have been damaged or the cable may not be properly connected, preventing it from receiving signals from the computer. 3.Internal Failures:

It is possible that the motherboard or other components are faulty, causing the computer to malfunction, which in turn causes the computer to lose power. Workaround:1

Check the power supply: Check whether the power plug and power switch are normal, and confirm that the power cord is tightly connected to the socket. In addition, the power supply can also be replaced to solve the problem.

2.Replace the monitor: If you're sure you're having trouble with your monitor, you can replace the monitor or make sure the cable is connected to the correct port for the creep.

3.Check for internal faults: If you are able to rule out the power supply and monitor issues, it is possible that the internal components of the computer are faulty, and it is recommended to disassemble and clean the inside.

I hope you can start the cherry blossoms to help the little master.

Summary. Hello, the power failure of the computer host as soon as the monitor is turned on may be due to the following reasons,1If the monitor is powered off after powering on, it may be a problem with the graphics card, check whether the power cord of the graphics card is plugged in; 2.

If the power cord of the graphics card is plugged in, check whether the BIOS settings of the graphics card are correct; 3.If the BIOS settings are correct, the graphics card itself or the graphics card interface on the motherboard may be damaged, and a new graphics card needs to be replaced. 4.If the same situation still occurs after replacing the new graphics card, it may be that the graphics card interface on the motherboard is damaged and you need to replace the motherboard with a new one. 5.

If the same situation still occurs after replacing the motherboard with a new one, it may be that there is a problem with the power supply and you need to replace it with a new power supply.

Hello, the power failure of the computer host as soon as the monitor is turned on may be due to the following reasons,1If the monitor is disconnected after powering on, it may be a problem with the graphics card, check whether the power cord of the graphics card is plugged in; 2.If the power cord of the graphics card is plugged in, check whether the BIOS settings on the graphics card are correct; 3.

If the BIOS settings are correct, the graphics card itself or the graphics card interface on the motherboard may be damaged, and a new graphics card needs to be replaced. 4.If the same situation still occurs after replacing the new graphics card, it may be that the graphics card interface on the motherboard is damaged and you need to replace the motherboard with a new one. 5.If the same situation still occurs after replacing the motherboard with a new one, it may be that there is a problem with the power supply and you need to replace it with a new power source.

Where is the power cord of the graphics card.

Hello, the power cord of the graphics card generally has 6 pins and 8 pins, which are connected to the 6 pin and 8 pin power ports on the motherboard. Generally, the power box of desktop computers has a 6-pin or 8-pin power cord inside, which can be directly connected to the power connector of the graphics card. Some console PCs require the purchase of an additional 6-pin family adapter or an 8-pin power cable to connect to the power connector.

Normally, the graphics card's power cord will be plugged into the power outlet on the back of the computer case. The power connector of the graphics card is generally 6 pins, you can take a look.

1.First of all, we have to check whether the power supply of the display is plugged in, whether the power supply is turned on, and it is estimated that many people have committed this aspect;

2.The second reason may be that the capacitor is broken, see if the capacitor on the motherboard is bulging;

3.If the above two points can't solve the problem, it is better to take it to the computer shop to repair it, after all, they are professional.

How big is your power supply, you can install the graphics card on other computers to try, if it is normal, you have to consider whether the power of the power supply is not enough, many assembly machines are not reasonably configured, the power supply capacity is small, there will be such a problem.

Problem Analysis:

There are two situations: the screen is not powered on (the power indicator is not on) or the power is turned on but there is no signal or "no sighal" is displayed, the former means that the power is not on or the power cable is in poor contact or damaged, and the latter is generally the memory module or display data cable is not in good contact, or the memory, graphics card, monitor or data cable is damaged.

Handling suggestions:1If the monitor is powered on but no signal is displayed, turn off (if short pressing the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, plug in and unplug the memory module again, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), and then turn it on after installation. The above may need to be repeated, and if it doesn't work, you need to replace the memory module.

If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.If the monitor is not powered on (the indicator light is not on), check whether the power switch is turned on, then check the back of the monitor, plug the power cord connected to the monitor upwards (the power cord can be replaced if possible), and check whether the other end of the power cord is powered on to the outlet.

4.If the display can be displayed when connected to another monitor or the display of this machine is connected to another normal host and still cannot be displayed, it means that the monitor is damaged and needs professional repair.

It is very likely that it is caused by CPU overheating, it may be that the CPU fan has made the stove obstructed, or the thermal conductive silica gel between the CPU and the fan has fallen off, and it can be taken to the computer hospital to take a look, if the CPU is overheated, it can be solved for almost more than 100 yuan.

Supplement: There is a layer of thermally conductive silicone between the CPU and the CPU fan, and this layer of glue will fall off after a long time, resulting in poor contact between the CPU and the CPU fan, and the CPU can not be fully dissipated, so after starting for a period of time, the CPU thermometer on the motherboard will detect that the temperature of the CPU is too high, in order to protect the CPU from being burned out, so that the power will be automatically cut off. Thermally conductive silicone is sold on the market, it is very cheap about 10 yuan a small bottle, but it is not a professional to make it, and it needs to be reworked, which is very troublesome, I still advise you to go to the computer hospital to repair it, it will not be very expensive.

Of course, there may also be a problem with the CPU fan, after a long time, due to static electricity, the CPU fan will be covered with dust, resulting in slower rotation, unable to dissipate heat normally, and there will also be the above problems, if it is a fan problem, either clean it or replace it with a new one. There are not many reasons for automatic shutdown, but they are generally as follows: (1) The operating system is overloaded, and the software is set to automatically restart to achieve the purpose of optimization.

2) The power API management module is faulty, and the temperature measuring probe fails, because the temperature is 60 degrees as soon as it is turned on, and the protection temperature can be adjusted higher. (3) When the power supply itself fails, when the system load is too large and the virtual memory is increased, and the load of the hard disk and CPU is accelerated and too heavy, the power supply cannot withstand the voltage increase due to the fault, resulting in self-power shutdown and replacement of high-power power supply. (4) If an automatic shutdown occurs when operating the application software, it may be caused by the program software, uninstall it first and then reinstall it, if not, it means that the program software itself has an error and cannot be used.

5) If it is caused by a virus, it is a virus that kills the virus. (6) If it automatically shuts down without operating, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Power Usage Scheme.
