It depends on what hardware makes the sound. Generally, it is nothing more than the hard disk, the cooling fan, or the squealing of the graphics card and the poor contact between the connecting lines. It is recommended that you listen carefully first. The hard disk is normal if the sound is not too loud. If it is the voice of the graphics card, it usually appears in the load state. At this time, you can copy the machine for further testing.
If some element leaks electricity or the inductance pin barks, the element quality is not very good, but it is a qualified product, which will not affect the use. Of course, you can also go to the after-sales service and ask them to repair it for you.
If the sound is continuous and harsh, it may be a warning sound from hardware failure such as hard disk, video card, etc. It is better to find a professional for diagnosis and maintenance
It may also be that the power supply or hardware equipment is overheated. It is recommended to check the cooling system and operating procedures to avoid long-term use under high load
It may be caused by dust accumulation due to poor operation of the internal cooling fan of the computer.Clean the dust or check whether the lower fan needs to be replaced
