As soon as my computer is turned on, the host rings, it turns off, and it turns on again, what is th

Maybe it's a fan issue.

The sound of the computer mainly comes from the following aspects:

1. The noise generated by high-speed running equipment, such as the noise of optical drive rotation, will have this phenomenon after the aging of optical drive or poor quality optical drive. The sound emitted when the hard disk is read and written, the new hard disk is so small that it is almost inaudible, and the sound of the hard disk when it is running is not far from a failure.

Second, the noise generated by the fan, such as the motherboard processor fan and the power supply fan will produce noise, generally does not affect the use, when the noise is loud, see if you can add lubricating oil to reduce the noise, it is really not possible only to replace the new fan.

3. The chassis is best placed on a hard floor, as it is likely to cause noise due to the vibration of the chassis caused by the rotation of the fan and the hard disk when placed on soft media.

Fourth, in winter, sometimes the noise of the computer will be very loud when it is just turned on, and the sound will be reduced a lot or even inaudible after running for a period of time.

Isn't the wood cleaned Haha Gray big Have time to clean it up Maybe your fan can have a little problem Turn it on yourself and take a look I hope it will help you.

Check that the CPU fan and the power supply fan are wired.

If you want to brand the machine, you can redo the system.

If you want to assemble the machine, reinstall the motherboard driver.

Listen, it's ringing there. Half are CPU fans, or power supply fans.

It could be that the hard drive parts are loose. If this happens regularly and the noise is really loud, it should be sent for inspection. In fact, computers, especially laptops, will have normal sounds when they are turned on, and some sounds will be made during the operation of the computer, which is the internal operation of the host.

The loud noise of the computer when it is just turned on is generally the cause of the fan. Due to the lack of oil and dryness, the fan starts with a large torque, and the noise is large, and when the speed is normal, the torque is smaller, and the noise is reduced. If the noise is too loud, the CPU fan, graphics card fan, or power supply fan in your computer needs to be refueled.

There is a circular self-adhesive sticker in the center of the bottom surface of the fan, which can be uncovered to reveal the internal shaft of the fan. Use a toothpick dipped in a little sewing oil (about the size of a grain of rice) and add it. Attach the sticker again.

In addition, check whether the chassis vibrates, and if the host is not moved slightly, or the handle is pressed against the cover of the case, you can try it out.

The method of hand test inspection is that if the sound of pressing on the hand is low, it is the case vibration, check whether the cover plate screws are aligned, or the quality of the case is too poor. If there are no big changes.

It should be the fan's problem. If you don't have experience in repairing computer hardware, it's better to find a familiar person to help, it's easy to solve, to determine which fan it is, you only need to temporarily unplug the power plug of different fans to quickly tell.

The sound of the fan, very normal.

Solution: 1) Check whether the fan in the case is working properly.

2) Clean up the dust inside the chassis (the correct way is to blow the dust with a bicycle pump).

3) Put a drop of sewing oil on the bearing of the cooling fan, which can effectively reduce the noise! Don't drop too much, just one drop and you have to judge what the sound is, what part it comes from, now the weather is cold and dry, the moisture in the air is low, it is easy to cause the fan in the host to make abnormal noises. It is recommended that you check the fans in the host computer when you turn it on, such as the CPU fan, the fan behind the power supply, the graphics card fan, or the main chassis evacuation fan.

In terms of judgment, you can choose to temporarily cut off some fans or gently press one or two of them with your hands, find the problematic fan in this way, replace the fan after finding it, and add a little lubricating oil to the problematic fan if possible.

When the POST is turned on, there must be a sound. The motherboard rings differently from computer to computer.

The meaning of the sound emitted when the machine is turned on is as follows:

awardbios

1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please enter CMOS

setup, resetting the incorrect option.

1 long and 1 short: There is an error in the memory 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 and 9 short: motherboard flash

RAM or EPROM error, BIOS corruption. Try a different block of flashram.

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

amibios

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

2 Short: The memory ECC verification error is incorrect. in CMOS

Setup can be solved by setting the memory ECC check option to disabled, but the most fundamental solution is to replace it.

Memory. 3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

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: BIOS chip check and Kuambi 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 should be cautious and the data cable is not inserted blindly or the graphics card is not inserted firmly.
