Why do computers make noise
It’s really annoying to hear computers making noise, especially when you’re working in an office or a place where silence is preferable. Be it a continuous buzz, a grinding noise or a loud thunder, the irritating sounds tend to curtail the pleasure of working on them. Several factors may contribute to create and aggravate that persistent humming, which you definitely need to be aware of so that you could take curative action in a timely manner.
First, you need to check your processor fans (Case fans or CPU fans) for dirt and dust accumulation, or should replace them when they become older. Once you remove the dust from the processor fans, you will notice a perceptible decrease in noise. However, if it’s not the case, then the fan may be damaged. Therefore, what you need is a replacement. In the second case, the loud clunking or a thunderous sound may be due to hard drive failure. Again, in this case too, you need to replace your hard drive to avoid any subsequent harm to other computer components. However, before you replace it, make sure that you have created a back up for all your data onto an external drive. Finally, the power supply may also cause noise while providing power or ventilation to your computer. When power supply fan fails or it’s in a bad shape, it can cause an excessive amount of noise.
Computers also make a soft whirling noise when you are accessing a CD-ROM, DVD, or other disc drive, which is perfectly okay.
