The monitor suddenly has no signal, just restart it, why!

The monitor or the cable is gone.

The former means that the circuit is not on, or the power interface or power cord is poor or damaged, and the latter is generally due to loose or oxidized memory modules and poor contact, or poor contact with the display data cable, or damage to the memory cable, or damage to the memory, graphics card, display or data cable.

Handling suggestions: 1. If the display is powered on but shows no signal, turn off (if the short press on the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off Jian Huizao open the case, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail can also be scraped and removed), if possible, it can also be installed in different memory slots, and then turned on after installation (before operation, you should also release your static electricity by touching the wall with both hands or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice is fine (pay attention to the location: the right and left sides of the chassis in the shell that does not have an interface in the back, the positive ** attention of the shell: don't use too much force, of course, you can't be weak).

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 are invalid, turn off the power and open the chassis, replug and unplug 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 plug 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 socket.

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

Try a different battery.

The temperature is too low for a piece of hardware to work on the first boot, and it will automatically recover when the temperature rises.

There is no signal on the computer boot monitor, teach you 5 solutions.

It may be a malfunction caused by the poor contact of the data cable connector of your computer hard disk, you unplug it and plug it in a few more times to see if the computer can start normally, and then check other problems to see.

First of all, check if there is not enough power! Then look at the graphics card slot for dust! Then consider the problem of motherboard reconstruction! If the above two points are normal, you can only repair the motherboard, and under normal circumstances, you can't repair the motherboard!

1.The graphics card is not in good contact with the plug-in, the reason is estimated to be too much dust, and it is estimated that your resolution is too high and does not support your monitor. After changing the monitor, adjust the resolution and you're good to go.

2.Your situation should be out of the power supply, you can change the power supply to try, your black screen should be caused by the graphics card crashing, let's see, is it the heat dissipation problem of the graphics card, or the power supply of the graphics card, take a look.

Let me tell you for sure: at least the motherboard is broken. Or if you move to my house, I'll help you check, in addition to the motherboard, which is broken, my home is in: Huaguo Mountain Water Curtain Cave Building B Building 3 Unit 2nd Floor.

But you check me or anti-factory, it is recommended to find a trustworthy computer company to check out the anti-factory, some people say that the anti-factory is actually their own repair, and the replacement can be replaced, you still can't see it, understand!?

Your machine is an old machine, right, it's not good in the first place, bumps and bumps where it should be touched, and it's not good to touch it, just make a little spark or something. What's more, you may have been struck by lightning, and your machine is not the person who has been struck by lightning 9 times in your life.

I've told you my address, and if you don't give it to me, you're too bad, hoho

There is no signal on the computer boot monitor, teach you 5 solutions.

The first thing we have to find out the cause of this situation is the power supply problem, if the computer automatically restarts, half of the time there is a power supply problem, the voltage is unstable, resulting in insufficient power supply. At this time, the solution is to change to a new power supply.

The second may be caused by the poor contact between the memory slot on the motherboard and the memory, so you need to dial the memory that is present, and then use the eraser to wipe or blow on the place where the gold finger is pointed, the main purpose is to do a dust cleaning. Or do a replacement problem and it will be solved.

The third reason for rebooting is related to the heat dissipation. It may be that your CPU temperature is too high, the computer fan is not working, and the computer temperature cannot be lowered, when the temperature reaches the set temperature of the motherboard, the motherboard starts protection, and it will automatically restart, and the solution to the cause will naturally appear. All you have to do is bring the fan back to work automatically to cool down the CPU.

The third common situation is: there is virtual soldering in the video memory integrated block of the graphics card, which causes poor contact with the motherboard after powering on, and it will automatically restart.

The fourth reason for the reboot is, congratulations on winning the lottery. If you have a virus in your computer that damages the boot area and the system, it will reboot repeatedly, and the solution to this problem is to fix the boot area, so you will have to reinstall the system.

The first possibility is that the memory module is in poor contact with the motherboard socket. Open the main chassis, unplug the memory stick, see if the gold finger has been oxidized, wipe the gold finger with an eraser, insert it back into its original place, if the situation is still the same, try to plug it in another slot, generally there are four memory module slots side by side.

2 4 The second possibility is that there is a problem with the power supply. Any capacitor in the power supply may cause the computer to constantly boot and restart. If it's really a problem with the power supply, just change the power supply.

3 4 The third possibility is that there is a problem with the graphics card. The memory part of the graphics card may be in a high temperature state for a long time, and some of the original virtual soldering problems will appear. Either take it to the repair area for soldering, or change to a graphics card can solve this kind of problem.

4 4 The fourth possibility is that the electrical voltage is unstable. This possibility is estimated to be a little more likely to occur in the summer. In summer, the refrigerator and air conditioner are turned on together, which may cause the voltage to be unstable and the computer to keep restarting.

Precautions. Basically that's what it should be, you can take a look.

It may be that there is a problem with the memory module, and the guide computer cannot start normally, so you can try a new memory module.

The signal cable of the monitor is not connected to the main unit!

It may be a problem with the hard disk or a hardware problem, so let's take a look at the after-sales service.

Plug the memory back in.

The phenomenon you described should be a hardware problem, there may be a problem with the power supply or motherboard, check it carefully.

It's best to go to the after-sales service!

You loosen the six threads of the motherboard, try again.

Try reinserting the memory!
