What should I do if the keyboard on the computer boot display screen does not respond

Is it the keyboard or the screen that doesn't work?

Describe the problem specifically.

The problem that the computer boot monitor and keyboard do not respond and the solution:

1. The monitor plug is loose or the signal cable is damaged. Plug in tightly or connect with a new cable.

2. The keyboard socket is loose or damaged. Plug it in tightly or try it with a good keyboard.

3. In-machine volume.

Too much dust, causing the fan speed to be low. Remove the dust.

4. The CPU is overheated, and the motherboard self-test is over-temperature and shut down protectively. Check whether the CPU fan is turned on and rotated, if it does not rotate, the fan is broken, replace the fan. The motherboard fan plug falls off and plugs it back in. If there is a fault in the auxiliary circuit of the motherboard, check whether there is an electrolytic capacitor.

Drum top, replace the electrolytic capacitor or send the motherboard for repair.

The main reason for this situation is that the power supply on the host is insufficient, and the DC voltage is generally about volt, so at this time, it only needs to be rebooted and started by the computer.

In this case, most of the things are memory. Shut down the computer first and open the case, then unplug the memory module, use the eraser to erase the position of the gold finger, and then plug the memory back in, and boot the test. If it is not normal, it is a problem with the south bridge of the motherboard, and the motherboard needs to be repaired.

If the computer boots up the monitor and keyboard does not respond, it means that the computer has crashed and has not been opened normally, you can plug and unplug the memory module or hard disk and graphics card, and come out and wipe the gold finger with an eraser.

See if the computer is powered on, if it is not, just press the switch, the monitor and the keyboard are certainly not responding.

After confirming the power-on, if there is still no response, please check the signal cable of the monitor, if there is a problem with the signal cable or loose, there will be no response either, the keyboard may react, but the monitor does not respond, the reaction of the keyboard can not be seen. You can unplug the signal cable and reconnect it.

If the power is on, the signal cable of the display is also connected normally, and there is still no response when it is turned on.

The troubleshooting process is very simple, if the monitor is powered on and turned on, if you unplug the signal cable, there will be a prompt that there is no signal connection, indicating that there is no problem with the monitor. After confirming that there is no problem with the monitor, please check the graphics card, unplug the graphics card, wipe the gold finger with an eraser, clean up the dust with a soft brush, plug it back in, and turn it on after connecting, if there is still no response, please unplug and clean up the memory and other parts that can be plugged and plugged. Generally solves the problem.

If the above means are useless, it is estimated that the motherboard is broken.

1.It may be that the graphics card or monitor is faulty; If you use a discrete graphics card, you can unplug the discrete graphics card and try it with the motherboard integrated graphics card, or change the output port of the graphics card**; If it can be turned on normally, the former can try to use alcohol or an eraser to clean the gold finger part of the graphics card, and the latter may be the output port is faulty; 2.Try to change the monitor, but the probability of the monitor is relatively small, if the display indicator is green after turning on, but there is no image, it may be that the display is faulty; 3.

There may also be a failure of the **line, poor interface contact, etc., change a **wire to try to see if it can output**; 4.After powering on, the keyboard light is on, press the caps lock key on the keyboard, that is, the caps switch key, if the caps lock light can be switched, it means that the host has been able to start normally, but the display part is faulty.

Questions. I turned on the computer only the fan inside the case was turning, and the mouse and keyboard monitor outside didn't respond.

It may be a problem with the graphics card, if it is a discrete graphics card, clean up the dust and take a look, or change to the integrated graphics card socket to see if the display can be lit.

It may be caused by a problem with the computer hardware, usually a problem with the memory module or graphics card. It is recommended to replug the memory module and try it first.

The computer's boot monitor and keyboard are not responding, indicating that there is a problem with the main unit.

Suggestion. Shut down and reinstall the memory module.

If it's still the same, you need to check the parts. Power supply, hard disk, motherboard, etc. are detected step by step.

It is recommended to send it to a computer repair center for detailed testing.

Why is the computer booting up monitor and keyboard not responding? If the computer boots up the monitor and the keyboard are not responding, this is because it may be that you want to use the keyboard, there is no response, the monitor should be responsive, the keyboard should not respond, this may be the beam connection is not good, or the host of the computer is broken.

It means that there is a problem with the motherboard or power supply.

If it may be: 1. The motherboard may need to be repaired; 2. If there is a problem with the motherboard settings, it is recommended to restore the BIOS to the factory default settings; 3. Turn off the computer for a few minutes and turn it on again, sometimes the problem can be solved by itself. Step 1:

Unplug all unnecessary external equipment, only leave the mouse keyboard and monitor and power cable, after turning on to see if it can be used normally, if it can, it means that other devices cause the mouse to be unusable, plug it in one by one to boot the detection, see what is caused by the bottom. Step 2: If the above method does not work, follow the second method.

Press the del button on boot to see if you can enter the BIOS normally, if you can, it means that it is unusable due to system reasons, and reinstall the system. If pressing the DEL key does not enter the BIOS normally, then there is a problem with your motherboard mouse interface and send it for repair.

Questions. Now it's just that you can't enter the system by pressing del.

Can any other keyboard be used?

1. Check whether the keyboard of your computer monitor is connected correctly.

2. Check if your power is turned on normally.

The computer boots up, the monitor keyboard doesn't respond, it may be because there is a hardware problem.

This situation is called power-on without display, generally caused by the host, since the memory, graphics card and motherboard have done the most basic is not good, it is best to go out to find someone to help you detect, you need to use the power supply load to test the power output, if the power output is normal, then use the debug card to detect the fault parameters.

Is there a display? What's shown? If the keyboard doesn't respond, it may be a system problem, it may be a socket problem, and it may be a keyboard problem, your problem is not clear, so I can't judge that it is a ** problem.

It may be that the computer is faulty and fails to turn on the computer.

1. Your coms battery is dead. So your BIOS becomes factory set by default.

2. Your hardware has changed, and the BIOS configuration is different from your hardware.

To solve the problem, press F 1 to continue, or restart the boot button and the del button to enter the BIOS settings. In general, there is a selection of optimal settings for loading in the BIOS. You select it, press f10 to save and exit.

However, if your coms battery is dead, it must be replaced. Of course, if your console keeps the power on. (It's power off, but the power cord is constant) your BIOS information can also be saved.

This also makes it possible to do this without changing the COMS battery.

Are you talking about the display showing nothing after turning it on? "When the computer is turned on, the keyboard and mouse screen do not respond"What does that mean? I can understand that the keyboard and mouse are not responding, but is the screen not showing anything after you press the power switch of the host?

If you really don't know anything about the computer, it's best not to do it yourself, because even if the computer itself has no hardware failure, but in the current winter situation, it is easy to cause hardware damage if you do it yourself, according to my understanding, your situation is likely to be poor memory contact or static electricity in the computer caused by you can not turn on, although it may be a small problem, but it is recommended that you are still in the maintenance personnel, which will protect your computer, if you want to learn more about computer knowledge in the future, it is good to learn moreNow, don't be stingy with a little bit of money and cause the computer to really have hardware problems, don't know how to do it now in the winter human body has a lot of static electricity, there are hands to touch the things inside will burn out the things inside to find a professional to check it, your situation should not be a big problem, plug and unplug the memory, clear the CMOS battery This operation should be able to solve your problem, but I am afraid that you will have a bigger problem if you do not operate properly, For you, you can watch the professional can learn more, and you can also listen to his explanation,

1.Unplug the data cable connected to the monitor and the console, and turn on the power switch of the monitor separately. Generally, if the display is normal, it will display the manufacturer's information of the display or a prompt that the monitor is not connected, if it can be displayed normally, it indicates that the display is unlikely to be damaged.

2.Check that the exposure is good. You can check whether the contact between the graphics card and the monitor is good, whether the contact between the graphics card and the motherboard IO slot is good, and whether the contact between the memory module and the motherboard slot is good.

3.If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound.

If the memory fault is ruled out, only the CPU and the motherboard are left.

Dear, hello, I've kept you waiting, I'm glad to serve you, the computer host can be turned on, the keyboard light is on, the reason and method for the display not to respond are as follows: 1. After starting the computer, check whether the display has power, and if the display is not lit, please exclude it in the following order. 1. Replug (check) and replace the power socket of the monitor (before checking, please make sure that the power connection of the socket is normal).

2. Replace the power cord (go to the store and buy a new one) and connect the monitor and power supply. 3. Replace the monitor. 2. If the display can display the manufacturer's advertisement, please exclude it in the following order.

1. Replug the data cable, and then start the computer, if it can be displayed normally, please follow the steps below. 2. Replace the data cable between the monitor and the computer, and then start the computer after replacement. Check whether the display is normal.

2. Replace the interface between the computer motherboard and the cable or install a discrete graphics card.
