The computer rings 12 times in a row, and the machine monitor can t be turned on, what s going on, w

Constant ringing (long sound) – the memory is not plugged in or damaged.

Ringing non-stop – the power supply, monitor, and graphics card are not properly connected.

Unplugging the memory module, it should solve the problem.

The computer cannot be turned on and does not sound the self-test sound when it is turned on, and the display screen is black, which is caused by the damage of the computer's hard disk, and the specific solutions are as follows:

1. Shut down the computer and open the back cover of the case

2. Place the new hard disk on the hard disk shelf:

3. After that, fix the hard disk with screws

4. After that, connect the hard disk data cable inside the case to the SSD

5. Finally, place the hard disk rack on the hard disk rack in the computer, and the solid state drive can be used normally

There are times when our computer monitors take a long time to light up, what is going on? Let me give you a brief introduction to the reasons why it takes so long for a computer monitor to turn on! Hope you enjoy it!

Analysis and solution of the reasons why the computer monitor takes a long time to turn on:

The computer boots on the display screen for a long time to light up, there are about 2 situations:

One: the display is dark red at first, and it is actually displayed every few minutes, and then it has been dark red directly, which is the aging of the lamp, and it is necessary to find a professional computer maintenance solution;

Two: The display is not displayed after turning on, and it will be displayed after one or two hours, which is the aging of the chip, which is caused by the fact that the display is not turned off after the computer is often turned off, and it takes more than 100 yuan to change a piece.

Three: The display manufacturer can repair it, and the general home appliance maintenance department can also repair it, and take it to repair.

Analysis of the reasons why the additional display does not light up:

1. Check that the display is not powered on or turned on.

Generally, there will be a power-on indicator on the display, you can look on the display to see if the display has been turned on, generally if it is turned on, it will light up directly.

If you have pressed the switch and it still doesn't light up, then please check whether the power cord socket is powered on, try another socket, or try another power cord (generally speaking, the power cord on the LCD display and the power cord on the rice burger and the main chassis can be used universally).

Generally speaking, if you move the main unit frequently, when the light does not turn on, it is likely that the power cord is in poor contact or the wire inside is broken.

2. Check whether the VGA database of the monitor is plugged in.

When the power supply is okay. At this time, some information appears on the display, such as the display showing a prompt such as "no signal". At this time, it is necessary to check whether the line shown in the figure below is plugged in.

In addition, remember not to plug in the data cable of the display cable incorrectly, if you have a discrete graphics card, you should insert a discrete graphics card. If you don't have one, plug in the integrated graphics card.

There are also some netizens who may be independent graphics cards, but the display prompts "no signal", then it is possible that there is something wrong with the independent graphics card, first unplug the independent graphics card, clean up the gold finger part of the independent graphics card, and at the same time clean up the graphics card slot and then plug it back in.

The solution to the additional monitor not lighting up:

The first thing to do is to press and hold the power button to turn off the computer.

Remove the screws (usually two) on the back of the main computer and remove the case panels on the sides.

Open the case and you can see that there are two card slots next to the fan, and at least one card slot has a memory module (usually green) inserted into it.

If your computer turns on with a sound but a black screen, here are some things you can try:

2.Check the power status of the display stool liquid indicator.

Check that your monitor is turned on properly and that it is using the correct input mode (such as HDMI or VGA).

3.Reset your computer's hardware.

For desktop users, you can try removing the CMOS battery from your computer's motherboard, waiting a few minutes before reinstalling the battery, and then turning it on again.

For laptop users, try turning off the computer, unplugging the battery and power adapter, then pressing and holding the power button for about 30 seconds to release residual charge, then reinstalling the battery and power adapter and turning them on.

4.Enter Safe Mode for troubleshooting.

In some cases, Safe Mode may allow you to recover from a black screen state. In the Windows operating system, simply restart your computer and press the F8 key to enter safe mode.

5.Consider replacing the hardware.

If the above steps don't resolve your issue, it's most likely caused by hardware damage. You can try replacing some hardware, such as monitors, keycards, etc.

In short, when the computer has a sound but a black screen, you can refer to the above methods for troubleshooting, if the above methods cannot solve the problem, it is recommended to contact professional maintenance personnel for more detailed diagnosis and repair measures.

The hardware is tested, check the display to determine whether it is working normally, if there is, consider the system problem, it is recommended to reinstall.

Obvious. The monitor is breaking down. I believe that it will not be long before -0-It's going to have to be repaired.

This has never happened before.

Your monitor is broken either, take it out and take a look.

The solution to the black screen that keeps ringing when the computer can't turn on is as follows:

Desktop host: 1. If the CPU is overheated, clean up the dust of the CPU fan, and replace the fan if there is a problem with the CPU fan.

2. If the memory is caused by poor contact, plug and unplug the memory, wipe the gold finger part with an eraser, and re-insert it.

3. If the discrete graphics card is in poor contact, plug and unplug the graphics card, wipe the gold finger part with an eraser, and re-insert it.

4. If the motherboard BIOS is abnormal, unplug the power cord, cut off the motherboard button battery, wait for three minutes, and then reinstall the motherboard.

5. If the above operations cannot solve the problem, it is recommended to send it to the maintenance center.

Notebook: 1. Remove the battery on the back of the notebook, connect the computer only with the power adapter, and try to turn on the computer.

2. Only use the battery, do not connect the power adapter, if the boot is normal, then it should be caused by a problem with the power adapter or a short circuit in the power interface of the notebook.

3. Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go. Try to boot up, if the boot is normal, then it is only caused by the abnormal BIOS of the motherboard.

4. Unplug the power cord, remove the battery, open the back cover of the memory, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in.

5. If the above operations cannot solve the problem, it is recommended that the notebook be sent to the maintenance center for testing.

It is recommended that you try to change the power battery first, if it still doesn't work, the parts of the machine itself are loose or the chip is damaged by virtual soldering, common reasons: the memory is loose or the memory itself is problematic, reinsert the memory or change the memory to try; The power supply chip of the motherboard is soldered or aged, the screen cable is loose or the motherboard short-circuits the power supply circuit of the screen; Graphics card, south bridge, north bridge BGA packaging chip virtual soldering or damage, generally there are more virtual soldering, just add soldering.

Constant ringing (long sound): The memory module is not plugged in tightly or damaged. If you still can't reinsert the memory module, you can only replace one memory.

Ringing: The power supply and monitor are not properly connected to the graphics card, check that all the plugs are plugged in.

The computer cannot be turned on and does not sound the self-test sound when it is turned on, and the display screen is black, which is caused by the damage of the computer's hard disk, and the specific solutions are as follows:

1. Shut down the computer and open the back cover of the case

2. Place the new hard disk on the hard disk shelf:

3. After that, fix the hard disk with screws

4. After that, connect the hard disk data cable inside the case to the SSD

5. Finally, place the hard disk rack on the hard disk rack in the computer, and the solid state drive can be used normally

Dial the power and data cables of the hard drive.

Supplement: You open the case and listen carefully to see if it is an abnormal sound coming from the hard drive. If you're sniffing it, it smells burnt. Maybe you have two pieces of hardware that are broken.

Follow-up question: I heard the sound of the optical drive coming from the hard drive, especially the moment the optical drive entered the warehouse, it seemed to be stuck by something.

Follow-up question: The three fans are turned on (power supply fan, CPU fan, and graphics card fan all the time), as mentioned above, the first time I turned on the machine, it was the optical drive, as if it was stuck by something, I restarted it a few times, but the monitor has not been displayed, and then I felt that the sound was getting louder and louder, and there was a smell of being burned, and the power was cut off all of a sudden. I rebooted it again, and then I opened the case after it didn't work, and the three fans still turned.

Answer: 1Unplug the power cord, take out the battery, keep pressing the power button to discharge, and then put the battery back and dial the data cable and power cord of the hard disk and optical drive, and try it on. Is it a discrete graphics card?

Follow-up: It's a discrete graphics card, I'm not at home right now, I'll try it when I get home, and then buy an eraser.

If you feel that there is a temperature, it means that there is no problem with the CPU and power supply. This method can't be tried for too long, as long as you feel the temperature, you can dial the power.

Follow-up: I tried it at the time, and I felt the temperature, and I thought something must have burned out. At that time, I felt the smell of burning, and the power was cut off all of a sudden.

This is obviously a fault caused by the graphics card or memory.,If the motherboard has a set of graphics, try to use the set display.,If there are several of them.,Try to pull them out one by one.。 If it really doesn't work, send it to the repair station.

Replug the hardware and use the eraser to erase the gold finger The line is plugged in Borrow a graphics card and try it.

Clean up the dust in the console and give it a try.
