In this article we will be sharing a list of PC components that might make unusual noises. To assess which components are making the noise, first verify if any lights on your hardware device is on when you hear the noise. If you are experiencing excessive noise coming from the computer, it is likely that your device is the cause for the issue.
DVD-ROM, CD-ROM, Or Any Other Disc Drive
CD-ROMs and other disc drives might make a noise when the drive is operational. It is usually a soft whirling sound and only happens once the drive is accessed. The following is not normal:
- No sound.
- A clicking noise when the CD-ROM is accessed.
- Sounds when no disc is in the drive or when the CD-ROM is not being used.
If you encounter any of the above-mentioned issues, it is likely that the drive is faulty and must be taken to a professional like logifixcalifornia.com for proper repair work.
Fans
Case fans – these fans are commonly found in front or at the back of your PC. They usually make a low humming noise. However, if you hear any high-pitched or clicking sounds coming from the case fans, it is a sign that the fan is faulty.
CPU fans – some PC heat sinks might have a fan installed for keeping the processor cool. It is normal to hear the fan make a louder noise when you are working on your laptop. However, you should only anticipate hearing a slight humming sound coming from the CPU fan. Here are some problems that might cause extra noise coming from a CPU fan.
- The CPU fan might be loose which causes a vibration.
- A cable is hammering the fan which causes vibration.
- The CPU fan is faulty, causing excessive noise.
Hard Drive
The PC hard drive is a regular problem that causes extra noise. The hard drive must make some noise which is usually a low humming or a soft whistling sound. Unusual noises include repetitive, highly noticeable, knocking, humming noises or a loud thump. If you hear any of these sounds, it is recommended to have computer technicians to have a look and determine whether it needs repair or replacement.
Modem
When you are connecting to the internet or some other PC, a loud screechy sound or a high-pitched noise might be heard from the onboard modem speaker. This happens when your PC is connecting to another PC. It must only be heard once your PC is making a connection with another PC.
Power Supply
It is possible for the power supply to generate excessive noise since it provides ventilation and power to the computer. However, if the fan in your power supply is dirty or faulty, it can cause unusual excessive noise.
If you notice constant excessive noises coming from the power supply, it could mean that the unit is bad or failing and needs replacing. We recommend first using compressed air to blow out the dust, hair, or dirt, which might have settled on the fan. If the noise persists, then the power supply might need to be replaced.
