After booting up, the host unit keeps ringing shortly

What is the short sound that comes out, whether it rings every second, a continuous drip, or a very short dripping sound.

What is the reaction of your computer at the same time as the alarm sound, can it enter the system normally?

If it rings every second, continuous dripping sound, and can't enter the system, it's because there is an error in your memory, the general situation is that the memory is not plugged in properly, unplug the memory, plug it in again, or change the memory slot can solve it.

If it is a very short tick drip sound, and does not affect the system, there is only one reason, a key of your keyboard is pressed, or the keyboard is not plugged in, causing the computer to think that you have been pressing and holding a key, in this case, you can generally plug the keyboard back in and out.

When the computer is turned on for self-test, the small speaker in the machine will emit a variety of kinds"Toot"sound, actually, this is to us"Pour out your heart and report the self-test information. Different BIOS,"Toot"The meaning of sound is also different. Listed below are two common BIOS ons.

Machine self-test sound information.

1. AMI BIOS

1 Short sound, memory refresh failed.

2 short sound, memory ECC check error.

3. Short sound, the self-test of the system basic memory (the first 64k) failed.

4. Short sound, the system clock is wrong.

5 short sounds, CPU error.

6 Short sound, keyboard controller error.

7. Short sound, the real mode of the system is wrong, and it cannot enter the protection mode.

8 Short sound, showing memory error (e.g. showing memory corruption).

9 Short-sound, motherboard flash ram or EPROM verification error (e.g. BIOS corrupted by CIH).

2. Award BIOS

1 Short sound, the system starts normally.

2 short sounds, regular errors. You should go to CMOS Setup and reset the incorrect options.

1 long 1 short sound, RAM or motherboard error.

1 long and 2 short sounds, display or graphics card error.

1 long and 3 short sounds, keyboard controller error.

1 long 9 short sound, motherboard flashram or eprom error (e.g. BIOS corrupted by CIH).

Uninterrupted long"Toot"sound, the memory is not plugged in properly or the chip is damaged.

The monitor is not properly connected to the graphics card.

Repeat short"Toot"sound, the power supply is faulty.

None"Toot"There is no display at the same time, and the power is not connected.

Ignore him, there's always a little bit of a voice.

Don't get him yourself.

If you don't understand it, don't mess around. Because that's how I broke a computer.

It is recommended to find a professional personnel repair.

Don't save this little money.

It was the memory module that was sent.

Unplug it and it's OK from the moment you plug it in.

Problem analysis: This noise is generally caused by the internal fans of the host, including the power supply, CPU, and graphics card fans. Due to the long use time or cold weather, the effectiveness of the lubricant inside the fan decreases, and the dust accumulates, the running speed of the fan decreases, and the friction increases.

If the noise resonates with the chassis frame, not only the loud noise but the entire chassis will vibrate. In addition, it is not excluded that the internal screws of the chassis may loosen and cause noise, and the mechanical hard disk will also produce noise when reading and writing.

Treatment suggestion: After a period of use, the lubricant inside the fan gradually recovers due to friction and heat, and the sound is reduced accordingly. If you don't see improvement, here's what you can do:

1. Use leather tigers, soft brushes, etc. to dust and lubricate the fan inside the case, or directly replace the new fan.

2. Tighten the screws on each part of the chassis.

3. If the mechanical hard disk is noisy, it can be replaced with a new hard disk or solid state drive.

There are three possibilities for the main unit to ring all the time:

1. Chassis resonance: Plug rubber pads on the feet and connecting parts.

2. If the fan touches the connection line and other debris, it is recommended to sort out the internal wiring of the case.

It's mainly a problem with the fan, it may be the CPU, it may also be the graphics card, if it is caused by a lot of dust, you can clean it up with a brush, if it is caused by too long use, you can take off the fan, there is a round thing such as a label on the inside of the fan, after uncovering, you will find that there is a hole inside, and you can put some lubricating oil on the hole!

You didn't say why it sounded, and I don't know. If you have two memory sticks, unplug one of them, and if you have a graphics card, try it.

1. Computer style

The fan sound is loud, and this du will be like this for a long time, but you have to know the reason why the fan sound is so big.

In many cases, the equipment has not been cleaned, and too much dust will cause the fan to be loud.

2. Because the CPU is the computing core of our computer, and the CPU operation will generate a lot of heat, which is dissipated by the CPU radiator, and the cooling fan and the heat sink play a role in heat dissipation.

3. Open the computer case and you can see that the heat dissipation fan and heat sink accumulate a lot of dust, which affects the heat dissipation on the one hand, and the operation efficiency of the CPU on the other hand.

4. The CPU cooling fan is generally not loud, and the main reason for the loud sound of the computer fan is the sound of the computer power supply fan, which is generally caused by the aging of the computer power supply.

5. The case cooling fan installed by the computer, because these fans are installed, the role of the whole computer is the role of heat dissipation, generally after a long time, the sound of the fan rotation will be loud, you can apply some oil to the fan.

First, when the system is started at the beginning, the CPU load is large, so the fan is also running at full speed to ensure that the CPU is not overheated, and the work is stable after entering the system, and the fan is determined to be running at normal speed or full speed according to the operation conditions. The second is that the fan oil is a little solidified in winter, and after a while, the oil melts and the fan does not sound.

If the old machine does not have this phenomenon, it is recommended that you change the fan (including CPU fan and power supply fan).

This problem is generally caused by the fan, is the landlord not cleaning the dust for a long time? It will be much better to open the case and clean up the fans.

It is generally caused by fans, there are fans on the CPU and graphics card, and the operation is a little astringent at first, but it is fine after running for a while. However, this phenomenon is expected to be more serious in the future, you can stop the machine, open the chassis, find the engine oil (if not, use vegetable oil to make do) point on the fan shaft, there will be a significant improvement.

If you look at the fan in the case and the fan in the case power supply, it should be caused by the lack of lubricating oil in the fan. In this way, the speed of the fan is not enough. You can remove the fan, turn it on from the back, and inject a little lubricating oil and it won't sound.

Tear down the panel and hear the CPU fan sound.

If the source is still a power supply fan or a graphics card, check to see if the graphics card has a fan or not, and whether it is the sound of the graphics card fan. If you don't feel the shake of the chassis, if it's caused by the shake, then try to plug a shock-absorbing thing (such as a tissue) to eliminate the sound. Most of them are still fan problems, it is recommended to disassemble and clean them!
