My computer won t boot and keeps ringing, what s the problem? What should I do?

Listen to the announcement. For your reference!

Now there are two kinds of BIOS commonly used in motherboards, "AMI and AWARD", and their definitions are slightly different due to different manufacturers.

1 Short: The system starts normally. Congratulations, there is nothing wrong with your machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

Below is the alarm tone for the AMI BIOS**:

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: ROM BIOS check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

Hehe. This is a typical case of poor memory contact.

You can unplug the memory module, wipe the gold finger, and plug it back in.

If it keeps ringing, it may be a problem with the graphics card, it may not be plugged in properly, or the graphics card is broken.

Look closely at the sockets in the case, most of them are loose.

Graphics card and memory reinserted!

My name is Zifan, and I am very detailed.

It should be that the memory has not been checked!

Answer: Hello, there are many reasons why the computer can't turn on, except for the optical drive, any hardware will cause the computer to not turn on. If the computer can't be turned on, there is no screen on the monitor, or there is no signal, no signal. If there are a lot of English letters on the computer, it may be a system or hard disk problem, and most of them are caused by the system.

Self-test and solution to the failure of the desktop computer that cannot be turned on:

1. If the host is not powered on, first check whether the indicator light on the chassis is on, put your hand on the power supply fan port, and see if the power supply fan is rotating, so as to judge whether the host is powered on; If the host is powered on normally, then see if the indicator light on the display is on, if it is on, the display is also normal when it is powered on, and both are normal, then the power supply fault is basically eliminated.

2. If the computer host or monitor is not powered on properly, please check that the power socket of the computer is in good contact, whether the power cord is broken, and whether the power strip is energized. If it is not caused by the above problems, it may be a problem with the host, and you can ask professional maintenance personnel to repair it at this time.

You can unplug it and check if there is bending, broken needle, and a lot of dirt in the D-shaped socket, which is a problem that many users often encounter. When connecting the D-shaped socket, due to uneven force, or forgetting to tighten the socket fixing screw, the socket is not in good contact, or due to improper installation method, the needle in the D-socket is broken or bent, resulting in poor contact, etc.

3. Open the side cover of the main chassis, check whether the CPU radiator fan and the power supply fan are running, if the fan is not running, then you can basically know the reason, either the motherboard or the power supply problem (if the indicator light on the motherboard is not on, it is a power supply problem).

4. If the CPU radiator fan and power supply fan are running, after shutting down, then we unplug the memory, use the eraser to erase the memory gold finger, change the memory slot and plug it in again.

5. If there are two memory, it is recommended that you unplug one memory and try to boot it up, if it can't be turned on, replace it with another (single) memory plug in, in case one memory is broken and the computer can't be turned on.

6. You can try to discharge the button battery on the motherboard (unplug the button battery and install it again), and then try to turn it on. If the computer has an integrated graphics card + a discrete graphics card computer host, most of the current computers are dual graphics cards, use a screwdriver to remove the discrete graphics card, connect the monitor cable to the integrated graphics card interface on the motherboard to try, if the computer can be turned on, it means that the discrete graphics card is broken.

The above is the self-check and solution to the failure of the desktop computer can not be turned on, if you encounter the same problem, you can refer to the above method, but if there is a problem with the hardware, then the computer can only be sent to a professional structure like Xunwei Quick Repair for maintenance.

The screen is black after the English characters are prompted at boot, and the host alarms, which is obviously a hardware problem.

It's useless to take pictures of the host.,The English prompt on the screen when you boot up is the key to solving the problem.。

The cause of the problem will be identified in the prompt, and only by clearing the cause can there be a correct solution.

The motherboard has alarmed! Take out the memory module first, take it out, and then install it back to see if it can be turned on, check whether the power supply starts normally when you turn it on, if the above two things are fine, it is estimated that there is a problem with the motherboard, I hope it can help you.

It may be that there is too much dust, clean up the dust.

Take out the memory and insert the gold finger with an eraser, and the graphics card will also be reinserted.

There are three possibilities: 1. The hard disk is not recognized, 2. It cannot be booted, and the system crashes, and 3. The power supply cannot be used for the hardware to boot.

1: Most of the memory modules are broken.

2: The hard drive is broken.

If it is a non-stop short ring, the main reason is that the power supply, the monitor is not well connected to the graphics card, etc. The following are the causes and solutions of different sounds:

1.Award BIOS POST alarm sound.

The instructions are as follows: 1 Short: The system starts normally and there is no problem with the machine.

2 Short: Regular error. Please go to BIOS Setup and reset the incorrect options.

1 long and 1 short: RAM or motherboard is wrong.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged.

Non-stop ringing: The power supply, the monitor is not properly connected to the graphics card. Check all the plugs.

No sound and no display: There is a problem with the power supply.

2.AMI BIOS POST alarm sound.

The description is as follows: 1 Short: The memory refresh fails. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Please go to BIOS Setup and reset the memory to Disable, but the fundamental solution is to replace a memory.

3 Short: System base RAM (first 640KB) check failed. Change memory.

4 Short: The system clock is wrong.

5 Short: CPU error.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. Just change the graphics card.

9 Short: ROM BIOS check and error.

1 long and 3 short: memory error.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

3。Compatible with BIOS POST alarm sound.

The instructions are as follows: 1 Short: The system starts normally and there is no problem with the machine.

2. Short: The system power-on self-test (POST) failed.

1 Long: Power error, if there is no display, it is a graphics card error.

1 long and 1 short: The motherboard is wrong.

1 long and 2 short: The display card is incorrect.

1 Short 1 Short 1 Short: Power supply error.

3 long and 1 short: keyboard error.

You may be talking about the BIOS alarm.

The long and short ones are the motherboard errors.

If it can be used.

You can restore the biom and you're good to go.

If not, put the coms battery on the motherboard and try to take off the round battery on the motherboard, and put it back on after a minute.

I used an eraser, but the graphics card still doesn't light up.

The symptoms are as follows: the computer can't be turned on after it crashes: when the power switch of the case is pressed, the computer is operating normally (the indicator lights and keyboards and mice are normal) I hear the whirring of the fans in the case, but the computer has not entered the self-test, and there is no self-test sound (buzzer in the case) sound response.

The display screen is dark and unresponsive throughout the whole process, and pressing the restart button can restart but the same symptom loops.

The overhaul is as follows: 1. Power off, disassemble the box board on one side of the chassis, and lay the chassis down to see all the viewing angles in the box.

Wang: Use a strong flashlight to check if there are any small insects attached to the circuit board for electric shock? All kinds of independent card boards (e.g. graphics cards, sound cards, with or without capacitors, electronic transistor bulging?)

Rising? Leaks? Char? Is there a screw wire falling off on the motherboard that causes a short circuit with the chassis? [After inspection, it is confirmed that the above phenomenon is none].

Smell: Is it normal to lean in close and sniff the inside of the case? Does it smell burning? [After inspection, it was confirmed that the above phenomena were also absent].

Q: Remove all memory modules! Then power up the console and power it on!

Witness to see if each piece of hardware is working properly! If the graphics card fan is turning? Does the main fan of the case rotate?

Does the CPU fan turn? Does the power supply fan turn? Does the hard drive turn?

After inspection, it was confirmed that all of the above are normal and rotated! [At this time, the buzzer in the chassis "Tick. Drip.

Cut: Power off the main unit again! Put away the static electricity in your hand (touch the floor with your hand), and then touch each independent board with your hand, such as the graphics card, the integrated graphics card of the motherboard, and actually check the temperature with your hand near the CPU, and feel if there is a certain part of the high temperature beyond the normal level.

After inspection, it was confirmed that the temperature was normal, and there was no part of the ultra-high temperature

After the above operations, it is basically concluded that there should be no physical problems in the machine hardware itself. At this time, the host has been powered off, and we have not yet installed the memory module we just removed. Well, let's remove the coin cell battery from the motherboard again!

Then press the power button a few more times! (Why do I need to press the power button when the power cord is not plugged in?) This means that the residual power inside the circuit board is consumed), if you are not at ease, you can let it stand for a while, and then press it a few more times to ensure that all the residual power is removed.

Then power on and press the power on button. Turn off the power again.

3. OK, after the above operation, insert the memory module back and the battery back to its original position. Then power it up and turn it on. You've finally heard the most familiar power-on self-test beep!

It turns out that your system crashes due to a software operation disorder and cannot be restarted and self-tested, and now it has been solved after you have a series of factory resets of the console.

Is the console's indicator light on? Are you sure it's not your monitor's fault?
