The length and number of flutes, listen carefully to this, this is the motherboard is reporting an error.

When the computer is turned on, the host keeps ringing, and the black screen can't be turned on.

Short, the system boots normally, indicating that there is nothing wrong with the machine Short, the routine is wrong, please go to CMOS Setup, reset the inaccurate option Long 1 Short, RAM or motherboard error. You can try to change a memory, if changing the memory module doesn't work, you can only choose to change the motherboard Long 2 Short, there is a problem with the monitor or graphics card Long 3 short, the keyboard gripper is wrong, please check the motherboard Long 9 short, the motherboard flash RAM or EPROM error, BIOS damage. You can change the flash RAM; 7. Constant ringing (long sound), the memory module is not plugged in or damaged.

Reinsert a memory module or change a memory; 8. It keeps ringing, and the power supply and display are not well connected with the display card. You can check all the plugs; 9. Repeated short rings, power supply problems; 10. No sound, no display, power supply problem.

1. "Didi." Continuous short tones.

In general, it is common for the host computer to have a power supply problem. However, sometimes when the output voltage of the power supply is low, the host does not alarm, but the hard disk is lost, the reading performance of the optical drive is poor, and it often crashes. When these situations occur, it is best to check whether the output of each voltage is low, when +5V and +12V are less than 10%, the above problems will occur from time to time.

Because the power supply has a voltage output, it is often mistaken for a problem with the motherboard or the hard disk, and a lot of time is wasted. When the DC component is reduced, the high-frequency AC component in the power supply increases, which will interfere with the normal operation of the motherboard, resulting in system instability, and it is easy to crash or blue screen.

However, this is the case on some types of motherboards from Intel and Gigabyte, if the system appears "Didi. A continuous short beep is not a power failure, but a memory fault alarm, which needs to be noted.

2.The sound of the ambulance "Woo la Woo La" was accompanied by the sound of the starter non-stop.

This situation is the system alarm sound of CPU overheating, mostly because of dust removal for the inside of the host, cleaning the CPU radiator or because of replacing a new CPU fan, because the installation is not in place, the CPU radiator and the CPU are not in good contact, there is a certain space or there are debris added in between, resulting in the heat emitted by the CPU can not be dissipated normally, and the CPU is as high as 80-90 as soon as it is turned on. If it is a CPU with a PIII or less, because the temperature test of the CPU is collected by a temperature probe near the CPU, the displayed temperature value has a certain error with the actual temperature value of the CPU, which is about 10-20 different. The temperature sensor of PIV's CPU is integrated inside the CPU, so the CPU temperature displayed by the system is more accurate.

Generally, as soon as the host is turned on, the CPU temperature prompted by the system is around 50, which is normal.

3."Tick. "Tick. 's continuous, spaced long tones.

This is the sound of the memory alarm, which is generally due to loose memory, poor contact between the gold finger of the memory and the memory slot, oxidation of the gold finger of the memory, and failure of a chip in the memory.

4."Tick. Didi" is a long and short continuous chirp.

This is a graphics card alarm, usually the graphics card is loose, the graphics card is damaged, or the power supply part of the graphics card of the motherboard is faulty.

5.There is no movement after two long tones of "beep", and after a while, you will hear the sound of "squeak" reading floppy drive.

If there is an image display, it will indicate that the system will boot from the floppy drive and is reading the floppy disk. If there is no floppy disk in the floppy drive, the system will prompt that no system cannot be started, and the system is suspended.

6.A short "beep" sound.

In general, this is a prompt sound that the system self-test has passed and the system has started normally. However, when some motherboards pass the self-test, there is no such prompt sound, and there is no sound at all. Also note that some motherboards may take a long time to self-test, and will wait five or six seconds before hearing a "beep" sound, which requires a bit of patience.

Under normal circumstances, there is only a short beep when booting, and some motherboards produced now do not have a beep sound. It may also be that the circuit was not connected at the time of assembly. If the original beep is now gone, check whether the sound-generating element (small horn, buzzer) and its connection circuit are damaged or in poor contact.

Maybe the buzzer is broken.

It's normal to have no dripping sound.

Are you an assembly machine brand machine is dripping very crisp because it has brand BIOS, you are not an assembly machine, the assembly machine does not have.

The CPU of the computer does not dissipate heat (the fan and the CPU cannot be contacted), and the CPU overheating automatic protection function takes effect.

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer's black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a bad contact of the graphics card, a damaged power supply, a damaged CPU, and a high temperature of components. There are also artificially caused by the black screen of the computer, such as the genuine verification of Microsoft China.

On October 15, 2008, Microsoft internal email, Microsoft will launch the Windows XP Professional Edition and Office Genuine Verification Program for the Chinese market on the 20th, at that time, the computer with the pirated Windows XP Professional Edition installed will be forcibly "black screen" (desktop background changes to pure black) once every hour, the menu bar of Office will be marked as "not genuine", and users of pirated software will encounter warnings such as "black screen" and "reminder mark" on the computer.

power caused. Damage to the host power supply or poor quality of the host power supply often causes our black screen failure. For example, when we add some new equipment, the display has a black screen failure, after eliminating the quality and compatibility problems of accessories, the quality of the power supply is not good, and the lack of power is the main cause of the failure, at this time, you may also hear the horn in the machine alarm 12 consecutive sounds, replacing the high-power and high-quality power supply is the best solution to this kind of failure. In addition, some motherboards have ATX dual power connectors, and the wrong choice of jumper settings can also cause this kind of failure.

accessories caused. Poor quality or damage to computer accessories can also easily lead to a black screen failure of the monitor. For example, problems with the motherboard (and the CMOS of the motherboard), memory, graphics card, etc., may definitely cause a black screen failure. There are often some signs of these failures, generally manifested as the display light is orange, when we can use the replacement method to replace the graphics card, memory, and even the motherboard, CPU try, is the fastest solution.

Connections between accessories.

The main cause of black screen failure is the incorrect or loose connection between the memory, graphics card, etc., and the motherboard. Moreover, if there is a problem with the connection between the graphics card and the monitor, this kind of failure may also be caused, until the AT power supply is not plugged in correctly, and even if the hard disk or optical drive data cable is reversed, it may also cause the boot black screen failure.

Press F2 or F4 when you boot up, find Boot, then move down to Seboot, change to another after entering, press F10 to save and exit.

1. The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

2. The power supply and display are not properly connected to the graphics card. Check all the plugs.

Do you decide whether it's a single sound or a long beep and then two seconds shorter and then repeat or a long and two short sounds.

Generally speaking, there are only two possibilities.

The first is that the memory contacts are not good.

The second is that the graphics card is not in good contact.

Unplug it and plug it back in, and it should be OK.

If it doesn't work, plug it in a few more times.

And then I'll give you a little trick.

Unplugging the gold finger with an eraser will work well.

Memory problems, just rub it off, if it doesn't work, change it to a new one.

In this case, the hardware is usually faulty.

1, for example, there is a problem with the mouse and keyboard, and the host makes a series of dripping sounds. It's tight. In this case, you remove your mouse key device and then turn it on, if it can be turned on, then there is something wrong with your mouse key and it needs to be updated.

If that doesn't work, use the following methods.

2. The host emits a regular dripping sound, which is a long dripping sound in bursts. Your memory may be loose or broken, you first unplug the memory and use a dry rag to wipe off the ash on the gold finger of the memory. Then put it back on.

If it boots up normally, then your memory is loose. If it still doesn't work, then try a different memory.

It may be a memory problem, use an eraser to erase the gold finger, it is not easy to change the memory.

Such a problem is generally due to poor contact of memory modules.

First of all, take off the power supply of the host, take out the memory module, wipe the gold finger of the memory with an eraser, and then clean the memory slot with a hair sweep or hair dryer, which should solve the problem.

The two alarms are a matter of the memory module, and the memory module is unplugged. Erase with an eraser and put it on!!

The landlord is caused by the poor graphics card and memory of your machine.

Open the case cover, remove the graphics card and memory, clean the lower gold finger with an alcohol cotton ball and reinsert it to make sure it has good contact.

Problem solving.

First of all, it depends on whether your host can be lit, if it can't be lit, then you can see if the memory module is loose, and the graphics card, the memory module is broken.

It should be a problem with the graphics card or memory, not plugged in well, poor contact, and it is estimated that the possibility of the graphics card is a little greater.
