The computer screen is not lit, and the console is still running

There is a problem with the cable connecting the screen, replug it.

Let's change the line that links to the display.

The reasons and solutions for the computer screen not lighting up and the host is still running are as follows:

1. Power failure. First of all, do a normal boot, see if your power supply is normal, listen to the sound of the fan and whether the power button is always on. If there is a solid light and the fan is running normally, it means that there is no problem with the power supply, if the power button is not lit, it means that the power supply is faulty and it is time to change.

2. Display the connecting cable. When the machine is not lit up after turning on, you can first see if the fan is running normally, and if it is normal, try to press the num key of the keyboard. You can also press the case toggle key and the scrlk key to see if the keyboard indicator is on, if it is normal, it means that the system is normal and there is no problem.

At this time, there may be a problem with the hardware display cable, try to replace a display cable to see if the screen can be turned on.

3. Excessive dust accumulation. When the computer equipment is used for a long time, there will be a lot of dust in the hardware inside, which will cause problems with the operation of the fan and the screen will not turn on. Generally, at this time, you can disassemble the host, and then use a small brush to remove all the dust on the fan, and then look at the fan of the CPU and graphics card, and if there is a lot of dust, remove it together.

4. Memory module problem. Poor contact of memory modules can also cause the user's monitor to not light up. You only need to press the card slots on both sides of the memory module, take out the memory module, and then use the eraser to remove the dirt and dirt.

Then plug it back again,Generally, you can solve the problem of not lighting the screen,Good friends can use another memory stick to try first,If it succeeds directly,It may also be a problem caused by the failure of your old memory module。

5. The problem of the graphics card and the memory module is almost the same, and the graphics card cannot be displayed after the problem, so the graphics card is unplugged first, and then the dust is cleaned, and then the dirt on the gold finger is erased with an eraser, and then inserted back to see if it can be lit.

The problem that the computer screen is not lit and the host is still running is mainly troubled from four aspects: screen switch, screen connection cable, screen internal fault, and host system. Let me talk about it from these three aspects:

1. The screen switch problem, the first thing to check if the screen is not lit is whether the switch of the display is turned on, find the switch and click it, if the switch is not lit, the switch is wrong, and if the switch keeps flashing, it means that there is a problem with the system.

2. Screen connection cable, check whether the cable connecting the screen is well connected to the host, and whether the plug is loose.

3. The internal fault of the screen, the inside of the screen will not light up, ensure that the host, screen switch, screen connection cable is no problem, the screen is not lit is the screen is damaged, you need to find a professional maintenance personnel for maintenance.

4. If there is a problem with the host system, the operating system installed on the host will be damaged, and a black screen will appear.

At this time, replace a good host, if the screen is on, it proves that there is a problem with the host system, reinstall the system.

Summary. The computer screen is not lit and the host is still running the analysis: the typical memory is not in good contact, and its essence is related to the quality of the motherboard.

It can be solved by the following methods. 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). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don'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.

Summary. 1.In general, if the computer screen is not lit up and the host is still running, there may be one of the following reasons:

1) Monitor failure: It may be that the monitor itself is faulty, or there is a problem with the power cord or connection cable of the monitor, resulting in the inability to display the screen normally. (2) Graphics card failure:

It may be that the internal graphics card of the computer is faulty, or there may be a problem with the power cord of the graphics card, which prevents the display from working properly. (3) Power failure: It may be that the power supply is unstable, the power supply is faulty, etc., resulting in the computer not being able to start normally.

4) Operating system failure: The operating system is abnormal, blue screen, etc., resulting in the computer not booting normally. The above is the possible reason why the computer screen is not lit up and the host is still running, if such a situation occurs, it is recommended to deal with it in time to avoid further losses.

It may be that the monitor itself is faulty, or there is a problem with the power supply or connection cable of the monitor, and the guide beam and the picture cannot be displayed normally. (2) Graphics card rubber key glitching: It may be that the internal graphics card of the computer is faulty, or there may be a problem with the power cord of the graphics card, resulting in the inability to display the screen normally.

(3) Power failure: It may be that the power supply is unstable, the power supply is faulty, etc., resulting in the computer not being able to start normally. (4) Operating system failure:

The operating system is abnormal, blue screen, etc., causing the computer to fail to boot normally. The above is the possible reason why the computer screen is not lit up and the host is still running, if such a situation occurs, it is recommended to deal with it in time to avoid further losses.

As described, at this time, you press the upper and lower case keys on the keyboard to see if the upper and lower case lights can be lit. If it can be lit, the graphics card is not working or the monitor ** line is not in good contact. If it doesn't light up, the self-test will not work, and the computer host will not work normally at this time.

The recommendations are as follows, 1Shut down and power off, take down the memory and use an eraser to erase the gold finger part. 2.

Press the power button 5-6 times quickly and wait for 2 minutes3Plug the memory back in, and then power it on. 4.

After that, it still doesn't work, get off the hard disk, turn it on again to see if you can enter the BIOS or if the keyboard light can be on, if not, the motherboard is a problem, and you need to send it for repair.

Dear, the computer screen is not lit, the host is still running, and the solutions are as follows: 1. Check whether the system is normal. If the host can turn on normally and hear the fan turning, but the screen is still black and the screen is not displayed, you can also pay attention to whether the light in the upper right corner of the keyboard is on, press the number lock or the case switch key at the top left of the keypad to see if the keyboard indicator responds. If everything is normal, it means that the system starts normally, but it is not displayed.

If it is abnormal, the system is not damaged, and the system needs to be reinstalled. 2. Check whether the connection is normal. If it is indeed a poor contact, just find the cable connecting the screen and plug it in.

If there is a problem with the line itself, you can replace it with a new one.
