The computer can t turn on, and the speaker keeps restarting automatically, what s going on?

CPU heat dissipation is not good, apply some thermal paste.

There was supposed to be a problem with the subwoofer of the speaker.

The speaker is the terminal that transmits the sound to the system with the help of sound, and its function is to convert the audio into the corresponding sound energy, and its energy space goes. It is a critical task for the human ear to hear directly, it deals directly with the human sense of hearing, which is very sensitive and has a special ability to complex sounds.

Frequently Asked Questions about Computers.

1. Poor contact of memory modules.

Solution: Open the case to fix the memory module, and at the same time dust the computer. This way can better ensure the operation of the computer. If your computer still has a blue screen, there may be a problem with the memory module. Consider replacing the memory module.

2. Incompatible software installation leads to blue screen.

Workaround: If you get a blue screen after installing the software, you must uninstall the software. If you still see a blue screen after uninstalling, it's for other reasons.

3. Computer poisoning leads to a computer blue screen.

Solution: If it is caused by a virus, you need to restart the computer and perform anti-virus operations. If your computer still has a blue screen, you can consider reinstalling the system.

If there is a problem with the filter circuit of your sound card or the sound card chip that comes with the motherboard, the speaker will have a continuous current sound, are you asking this, this can only be sent for repair.

If the other is a motherboard alarm, let's see if it's what cnttzy said.

Fan buffer is set in the BIOS face.

First, the software aspect.

1 Viruses. It is recommended to reinstall the system.

2 System file corruption.

Workaround: Overwrite install or reinstall.

3 Timing software or scheduled task software works.

If you set up in the Schedule Taskbar to restart or load certain workers, the computer will start up again when the scheduled time comes. In this case, we can open the "startup" item, check whether there are any executable files or other scheduled workers that we are not familiar with, block them and then boot them to check. Of course, we can also directly enter the "msconfig" command in "Run" to select the startup item.

Second, the voltage problem. The voltage is unstable.

Three. Hardware issues... A lot will cause. Poor contact of the graphics card, such as broken memory, CPU overheating.

It seems that there is a problem with the power supply, and the power supply is insufficient.

The buzzing sound is generally caused by mechanical vibration, and the sharp sound is generally the sound of the buzzer that comes with the brand's computer motherboard.

The moment the machine is turned on, there is no accident, it should be caused by the aging and wear of the exhaust fan used for heat dissipation.

When the fan speed is started from stationary to rated speed, due to wear and aging, mechanical vibration and noise are generated, and when the speed is higher, the noise is reduced and the wear is increased.

The fan here may be an accessory fan of the CPU cooler, a fan with large blades inside the power supply, or other fans installed by the user himself.

Solution: Replace the fan accessories, or lubricate the fan, it is recommended to change the fan, after all, the noise is serious, indicating that the mechanical damage of the accessories is serious, and increasing lubrication can only reduce the noise.

There is dust on the CPU fan, which needs to be turned on and cleaned.

Generally, it is the poor contact due to loose or oxidized memory modules, or the poor contact of the display data cable.

Handling suggestions:1If the monitor is powered on but no signal is displayed, turn off (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turned on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don't be weak).

The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

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.
