The computer is connected to the Internet, and suddenly the screen goes black and there is no signal

If your PC is assembled, it might be a compatibility issue. Most of the memory and motherboard are incompatible, and you can change to another brand of memory. Especially Jinshidun memory, this brand is famous, so there are naturally counterfeits.

Check whether the CPU temperature is too high and the screen is black.

Look at this tip**, there may be several reasons:

1. This ** is mainly caused by software or hardware incompatibility Let's take a look at whether it has been newly installed recently, or what hardware! Wouldn't it be nice to remove it and see if it would be good??

2. If the memory supply is too high and the compatibility is poor, you can generally replace the memory module, or take it off the motherboard and wipe off the gold finger with a skin like a skin and try again. Some new machine configurations will also appear like this,It may be caused by playing large games that are not supported,This mostly depends on the graphics card is not standard,You should choose an appropriate card,Don't think about what super memory,Super CPU!

Files are missing. If there is a sound after the black screen, reinsert the memory.

If you can't enter the system, reinstall the system.

Reconnect the hard drive and the memory is reinstalling.

I've had this situation before, and the detection is that the graphics card is broken, I don't know if it's a problem, refer to it.

Poisoned, or hacked, one of my classmates just played dnf, played this, played this black screen, and was controlled by someone and stole everything.

That's not right! Mine is the blue screen! My display is a virus program attack on my computer! Caused! Yours probably too!

Solution: 1. If the data cable connection between the computer host and the monitor is loose, it will also cause no signal to be transmitted to the monitor, then check whether the ** cable on the monitor and the computer host is not plugged in.

2. Usually after the computer is turned on, the motherboard will generally "beep" to prompt the boot successfully, indicating that the boot self-test is completed, that is to say, you can hear a "beep" sound to indicate that there is no problem with your motherboard, and the display signal, it is likely to be caused by the loose or damaged independent graphics card, it is recommended to replace the graphics card, and connect the VGA data cable to the replaced graphics card interface.

See if it can be displayed;

3. If you don't hear a "beep", it may be the memory module on your motherboard.

After unplugging the CPU, use an eraser to wipe the memory module, the part where the CPU is in contact with the motherboard, and then reinsert it to see if it can solve the fault;

4. Many computer motherboards will not have a prompt sound when they are turned on normally, for this kind of motherboard, as long as they look at whether the fan is turning after turning on;

5. If there is a sound after turning on, but the display has not responded, and there is not even a "no signal" prompt, then except for the VGA cable.

In addition to the possibility of looseness, it is likely to be caused by damage to the power cord of the display, the power supply or the circuit board inside the display, so you can only replace the power supply, if there is still no possibility that the display is broken;

6. For no sound after booting, if there is no sound before booting, it can be turned on normally, and now the screen is black.

It is a black screen without any prompt when switching on and off the monitor, it may be a problem with the power cord or power supply, and it can only be ruled out by changing the power supply or power cord, if there is a prompt "no signal", then it is a problem with the signal transmission between the motherboard and the display.

The computer boot display shows no signal, generally because the memory module is loose or oxidized and the contact is poor, or the display data cable is not in good contact, or the memory, graphics card, display or data cable is damaged. It has nothing to do with whether you are connected or not. How to deal with it:

1.Shut down (if short press 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, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). 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 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.

The solution to the black screen of no signal on the computer boot display screen is as follows: Prepare materials: computer 1, first of all, the interface between the display signal line of the computer host and the host computer is checked to see if it is loose.

If the line is loose, just plug it back in. 2. Unplug the signal of the display, and check whether the interface and line of the signal line of the display are damaged. If the interface and line are damaged, replace it with a new monitor signal cable.

3. Check whether the monitor interface on the computer motherboard behind the host is in good condition. If the monitor interface is rusty or the interface pin is damaged, the rust can be removed and the interface pin can be corrected. 4. Open the side cover of the host to check whether the interfaces of the motherboard are intact and whether there are rats biting the wire.

5. Check whether the memory, slot and memory module are firm next to the CPU of the computer motherboard. If it is loose, reseat it. 6. Check whether the interface between the independent graphics card and the motherboard is loose.

If it is loose, please reinstall the graphics card. 7. If the computer host starts and hears a buzzer alarm, please remove the memory of the computer to check whether there are traces of burning. 8. If the memory is intact, please wipe the metal part of the memory with an eraser.

9. After the computer host is checked, check whether the display input interface of the display is damaged. Mainly check whether the pins of the interface are deformed. To sum up, if the hardware settings are found to be damaged, replace them or go to a professional repair point for repair, the problem of no signal on the display will be solved.

The computer boots up and shows no signal, which is not related to the computer network or no network, the computer boots up and shows no signal and then the screen is black, which is a problem with the connection line between the monitor and the computer host, and it may also be a problem with the graphics card.

The monitor shows no signal because it is not connected to the computer, it has nothing to do with the network, please check whether the cable is loose and whether the computer is working normally

Summary. Hello dear,The first reason is that the display data cable is not connected or loose,If it is a newly installed computer,The first time you turn on,The host is running normally,But the display has no signal on the black screen,First of all, you need to check whether the display power is turned on,Whether the display is turned on,You can look at the display power indicator。

If the monitor is plugged in and turned on, check that the cable between the monitor and the computer is connected properly. It may be because the display data cable is not right, many new computers, because the motherboard and graphics card are the first interface, for independent display users, if the display data cable is connected to the motherboard** interface, this problem will occur. You'll need to connect the monitor cable to the discrete graphics card** connector in the console.

If the keyboard indicator is not lit, press the "num" key or the "numlock" key on the keyboard and there is no response, it may be that the memory is loose or the memory gold finger is oxidized, you can try to shut down the computer and power off first, and then remove the memory module, and then clean up the gold finger, and then reinstall, you can also try to install it in another slot. Motherboard BIOS error or static electricity can also cause this problem, we can try to restore the BIOS settings to factory settings, we remove the coin cell battery from the motherboard, leave it for a few minutes, and then install the coin cell battery in place to restore the initial BIOS value. It is also very simple to remove the button battery, pull the buckle outward, and the button battery can be automatically ejected, and you can remove it directly.

If you can't see the coin cell battery on the motherboard, it may be blocked by the discrete graphics card, please remove the discrete graphics card and operate it again.

The computer suddenly blacked out and showed no signal: you can see if there are any of the following reasons: 1. The data cable connecting the monitor and the host is loose, and the data cable can be plugged in and unplugged again; 2. The data cable connecting the monitor and the host is off, and the data cable can be reinserted; 3. The data cable connecting the monitor and the host is damaged, and a new data cable needs to be replaced; 4. If the memory module is loose, re-insert the memory module; 5. If the graphics card is loose, re-insert the graphics card; 6. The computer motherboard is damaged and needs to be repaired at a professional maintenance point; 7. Check whether the display is connected to power, if not, it can be connected.

Hello dear! We'll be happy to answer for you. The computer suddenly showed no signal on the black screenA:

Hello dear, 1. It may be due to the poor contact of the connection port of the ** line, and there may be a problem with the connected data cable; Try plugging the interface back in, or use another ** cable to check whether it is caused by ** cable; 2. After long-term use, the metal contacts of the memory, the gold finger of the graphics card or the connection port of the hard disk will be oxidized, resulting in poor contact, black screen, and no signal output; Turn off the power first, then try to open the case or open the bottom of the notebook, dial out the memory, use the eraser against the part of the gold finger, that is, the place where there is a copper sheet, wipe it back and forth a few times, and then insert it back into the memory slot; 3. This problem may occur after long-term use, the graphics card will fail, so it cannot be displayed normally, and the screen will be black when it is turned on, so it is recommended to repair or replace the graphics card.

There can be a number of reasons why your computer suddenly goes black and there is no signal, here are some possible solutions:

Check the power connection: Make sure that the computer's power cord is securely connected and that the plug is not loose or disconnected. You can also try plugging the power cord back in to make sure it's connected properly.

Check the monitor connection: Make sure that the data cable of the monitor (usually HDMI, DVI, VGA, etc.) is firmly connected to the graphics card slot of the computer. You can try plugging the monitor cable back in and out to make sure it's connected.

Check your graphics card connections: If you're using a discrete graphics card, not an integrated one, make sure the graphics card slot and power supply are securely connected. Sometimes the graphics card may slack and crash, resulting in no signal issues.

Check Display Input Source: Make sure the correct input source is selected for the display. Some monitors may have multiple input options, such as HDMI, DVI, or VGA, confirming that the correct input source is selected.

Restart your computer: Sometimes a black screen with no signal can be caused by a software or driver issue. Try pressing and holding the power button for a few seconds to shut it down, and then restart your computer to see if the problem resolves.

Check for hardware faults: If none of the above methods resolve the issue, it may be caused by a hardware fault. It could be a graphics card failure, a memory failure with a search, or a motherboard issue. In this case, it is best to contact a professional computer repair technician for overhaul and repair.

Please note that the above methods are for reference only and are not guaranteed to solve all problems. If the problem persists, it is advisable to consult a professional computer repair technician for further troubleshooting and repair.

Overheating, wait for 10 minutes to open again, can open the album is overheating, you need to change the CPU or the silicone grease of the dust card.

Memory failure. The motherboard is broken.
