Recently, some netizens have been talking about the topic of computer chassis screaming. Many netizens are very upset about the problem of computer squeaking. For the computer case humming, in fact, Xiaobian has encountered a lot, especially some computers that have been used for some years, it is easy to produce such problems, for the computer chassis slamming is not the CPU heat dissipation, Xiaobian can only say The possibility is relatively large, but it is not the only possibility. The following article briefly introduces the reasons and solutions for the noise of the computer case. The reason why the computer case is squeaking: The reason for the noise of the computer case is mainly caused by some hardware with a heat sink. For example, the CPU cooling fan is bad, the graphics card cooling fan is bad, and the power cooling fan is bad. The chassis is buzzing, which is why I can't tell the netizen exactly which one is the reason, because you also need to open the cover to listen, touch, and observe to know the exact answer. You may wish to use the above method to find out which hardware is causing the computer chassis to squeak. 1. First open the side cover of the computer case, then turn on the computer, then listen with your ear to see which hardware radiator is emitted. The key point is to listen to the CPU, heatsink, and power supply. 2, if it feels difficult to hear, you may wish to touch the power supply to see if there is a strong sense of shock, you can also shut down, hold the CPU fan or graphics card, and then turn on the power to see if there will be a buzzing, if No, then we can determine which hardware is causing it. Solution for the computer chassis squeaking: Found the hardware of the computer chassis, then it is relatively simple to solve, if the hardware surface is a lot of dust, resulting in poor heat dissipation, then we can clean the computer, the power supply Add some lubricant to the CPU and graphics card fan to solve the problem. If the computer case is squeaking due to poor hardware heat sink, and the problem remains after cleaning the dust, then you have two choices. One is that the computer is very old, and it is a bit squeaky and normal. Don't bother. If you really can't stand the noise, then take a test of Taobao to buy a cheap hardware. 1: If it is a "kakaka" or "嗡嗡嗡", the loud sound is the sound of the fan. Open the case and check if the fan's screw is loose. Check if the fan is running slower. The lubricant inside the fan may solidify. Especially in the winter when the weather is too cold, the lubrication will solidify.) Or there is no lubricant to add lubricant to the fan. It is also the case that the general fan will be used for a long time. It is best to replace it with a new one, 20 or 30 yuan. 2: If it is a "嗞嗞嗞" sound, it is normal that the hard disk will read when the hard disk is normally turned on. However, if the sound is loud, it may be that the quality of the hard disk is poor. Larger If you have not had this situation before, it may be that the hard disk has a slight physical bad track due to a large collision. It is recommended to find a professional to check. 3: If it is: 长 long sound is a memory problem (usually blue screen or can not start the computer) pull the memory up and use the eraser gold finger part to insert it into the memory slot when necessary. 4: CPU alarm sound When the CPU temperature exceeds the maximum temperature set in the BIOS, it will alarm the CPU temperature is too high. Check the heat dissipation of the fan and the chassis. Check whether the CPU fan is not smooth or the wind is not strong enough. If it is used for a long time, it will malfunction or the speed will slow down, and a new fan needs to be replaced. Another possibility is that the BIOS setting of the BIOS is too low. You can enter the boot and press DEL to enter the BiOS settings. Find the "CPUTempeue" (set the CPU alarm tone). Generally set at 60-70 degrees. Generally, these situations are solved manually. Look.
