Why is the computer turned on but the screen is not responding?

The computer host is coming and the screen is not responding, this is generally the computer hard disk started, but the display is not started, my general practice is to shut down the power, and then open the chassis, plug and unplug the motherboard memory, and then plug in the power to turn on the machine.

You can try to solve it from the following aspects:

First of all, you need to determine whether it is a monitor problem or a host problem, try to connect the monitor to another computer, if it works, it is the host problem, if it doesn't work, it is the monitor problem.

1. Display problems.

Check whether the electrical socket is powered on, check whether the cable interface (VGA or DVI interface) is connected (important), and try to change the cable if possible.

2. Host problems.

1) Check whether the graphics card is plugged in or loose, whether the fan is working properly, clean up the dust on the interface, and try to change the latest graphics card driver.

2) Clean up the dust of the whole machine, keep the heat dissipation normal, and kill and kill the virus.

3. If you can't try it, you can reinstall the system and take a look.

If it still doesn't work, it is recommended to repair it.

The screen is not responding, check as follows:

1.Check whether the plug of the display screen is plugged in well Don t think I'm doubting everyone's IQ, but it is true that many people forget this step and turn on the host without plugging in the display screen, and it turns out that the display screen does not respond and thinks the computer is malfunctioning, so.

2.Check the cable between the console and the monitor If the cable between the console and the monitor is bitten by a mouse, you need to replace one.

3.Check if the graphics card is broken If it is not for the above two reasons, it may be because there is a problem with the graphics card, if it is a problem with the graphics card.

4.The problem with the display itself If it is not for the above three reasons, it can only be that the display screen is broken, and if the display screen of the computer is used for a long time, it is recommended to replace one.

It is possible that the screen is not plugged in, or there is a problem with the computer's hardware, although the power is turned on, but the CPU and memory are not working.

The screen does not respond after the computer host is turned on, and there are generally two possibilities in this situation, the first is that the system is not successfully started and is still in operation, and the second is that the system failure does not respond.

First of all, we must see whether the switch of the computer screen has been turned on, if the screen has been turned on, the host is on, and the screen still does not respond in the future, it should be because the system is running too slowly, or there is a problem with the monitor.

Confirm that the host is operating normally, check whether the screen has power supply, confirm that the screen is in open mode, and check whether the signal cable is connected correctly and loosely, many of my colleagues have not connected it correctly.

The computer host is turned on, but the screen does not respond, it must be that there is a problem with the computer host or the screen connection is problematic, anyway, there will be a problem, you can check the case.

The computer console is turned on, but the screen does not respond. It's your graphics card or the connection between the graphics card and the display.

The computer host is turned on, and then the monitor does not respond, if there is a condition to change the monitor to see, or change the cable, if it still doesn't work, it may be a graphics card problem.

If the computer boot screen does not respond, it may also be that your monitor is broken.

But in your case, there may be a problem with the display, and sometimes this kind of problem will appear on my mobile phone.

a.First, check whether the monitor is powered on normally, check whether the indicator light of the monitor is on normally, and make sure that the power cord of the monitor is connected correctly.

You can try to turn the switch on and off, pay attention to whether the monitor is responsive, if you turn the monitor off and turn it on, the screen prompts 'no signal' or 'no signal', indicating that the monitor is powered on normally.

b.Make sure that the signal cable (VGA DVI HDMI DisplayPort) is connected to the monitor side - also make sure that the other end of the cable is firmly connected to the display output (graphics card) of the computer, try to plug the 2 ends of the display output cable back in and out to make sure that all the pins are not bent.

c.Confirm whether the display output of the monitor is set correctly, for example, if the display output of the monitor is HDMI interface, the display output of the monitor needs to be selected as HDMI display output.

d.Replace it with the same cable (VGA, DVI, HDMI, displayport) and reconfirm.

e.Connect the monitor to another computer, confirm whether the monitor outputs normally, and troubleshoot the monitor.

If the keyboard light is not on, it means that the host is not powered on, and the hardware needs to be tested.

Hello, I have seen your question and am sorting out the answer, please wait for a while Hello, I have seen your question and am sorting out the answer, please wait for a while Step 1, you must first check whether the connection cable between the monitor and the host is normal; Step 2: If there is no problem with the cable, there may be a problem with the hardware of the computer host. Let's turn off the host first, and remember to power off the power supply for safety; Step 3: After turning on the host, you can see the motherboard and other components, usually the display screen is black, and this fault is usually caused by poor contact of the memory module; Step 4: Pull the clips on both sides of the memory module outward with both hands at the same time, and the memory module can be easily taken off; Step 5: Use a clean small brush to clean the memory module socket, and then use a drawing eraser to gently wipe the golden part of the memory module interface, both front and back; Step 6: Install the memory modules back to the motherboard in turn, cover the panel of the main chassis, screw the main chassis screws, and plug all the connecting cables back into the corresponding interfaces;

The computer host is on, the monitor does not respond, usually the contact is poor, if there is no problem with the discharge, there may be a broken graphics card, you can only go to the repair place to repair, if necessary, change the graphics card.

1.Whether the power indicator of the display is on, whether there is a prompt that there is no signal, if both are the host fault, if not, the display is faulty.

2.Whether the keyboard light of the host is on, whether you hear the sound of windos starting the desktop, if it is both, the graphics card or data cable is wrong, if not, the host is dismantled.

3.Unplug the power cord, disassemble the left sideplate of the host, pull out the memory, wipe the memory gold finger with an eraser, and then put it back in place.

Check if the computer is suddenly shut down caused by hardware problems, if you don't understand the hardware equipment, it is recommended that you take it to a professional computer repair point for maintenance and inspection, please do not disassemble it indiscriminately, otherwise the hardware equipment will be seriously damaged.

If the graphics card display is fine, check the cable from the graphics card to the monitor.

Is the monitor on? Is the cable loose? Isn't it too dirty inside the host?

You can see if the keyboard light is on, and the keyboard light is not on, the host may not be powered on, and you need to detect hardware problems.

You need to change the monitor to try, if you change the monitor and it still doesn't work, you need to check the graphics card.

Summary. Clause.

1. Check whether there is a fault in the VGA interface of the connecting cable.

Clause. 2. Check whether the power supply is insufficient or aging.

I went into the BIOS to restore the system, and then I clicked on the wrong one, pressed F10 and he restarted, and then the host could be turned on, and the display was not displayed, and I also tried to pick the battery, wipe the memory, the graphics card, and it still didn't work, there was a discrete graphics card.

How to install the system if the computer can't be turned on?

You need to go to the shop to repair it, whether it is not cleaned up or the hardware is damaged, this needs to be seen by professionals on site.

Oh oh okay.

During operation, it may cause voltage instability, let the maintenance personnel show you.

I unplugged the discrete graphics card.,And then the built-in boot it looks like this.,How do you get this.。

Find a USB flash drive with a system, enter the safe mode and reinstall the system, you may delete the image, you are the operating system is missing, the problem is not big.

Dear, do you have any other questions, if not, can you give me a thumbs up, I wish you a happy life
