buzzing sound on cpu cabinet

[bond19]

Hi guys recently from my CPU cabinet getting buzzing sound while turn on the power...it increases the sound for some time and it turns off itself in few minutes and then it starts after some time..

Am not sure why this is happening suddently..could that be due to heavy load which we are providing??? even the cpu usage is approximately 29 % to 35% but still the problem

Could you please tell us, what is your computer specifications? Normally, at first boot, the fan on the cpu spins pretty fast until it boots to the windows but you are saying that it starts again after some time, so it definitely seems to be some other problem. Can you try to open the side of the cabinet and then boot up the pc and see what exactly is making the buzzing noise?

Have you done any overclocking on your system. I would suggest you to get into BIOS and load the default values and then restart the pc and check if there is no more sound problem. Also, incase if it continues then you probably will have to replace the Heat-Sink Fan mounted on the CPU, which normally does the buzzing sound.
