Question
Noise from computer.Answer
Below is a listing of components within the computer that may cause unusual noises to be generated. To determine what components are causing your issue, verify that lights on your hardware devices, such as the CD-ROM drive, are not on. If you are only encountering excessive noise when a device is accessed, it is likely that device is causing your issue.If the noise you are experiencing is occurring the entire time the computer is on, it is possible that any of the below devices may be causing your issue. Distinguish what device is causing the noise by reading through each of the below sections.
CD-ROM drives may generate noises when the drive is accessed. This 
noise should be a soft whirling noise when the CD-ROM drive is accessed. This 
noise should only be generated when the CD-ROM is accessed.
It is abnormal for a CD-ROM to experience any of the below 
symptoms.
- No noise
 - Clicking during accessing the CD-ROM.
 - Noises when the CD-ROM is not being accessed or no disc in the drive
 
If you are exhibiting any of the above issues it is likely that the 
CD-ROM drive is defective and it is recommended that it be replaced.
There are several fans in computers that help provide ventilation 
to the computer's components. Below is a listing of the fans that may be causing 
noises in your computer.
Case Fans
Case fans are fans commonly attached to the front or back of a 
computer. It is normal for most additional case fans to generate additional 
noise (usually a low hum). However, you should not expect to hear any clicking 
noise or high pitched noise from any of the case fans. When this occurs it is a 
good indication that the fan is failing or has already failed.
CPU fan
Although not installed on all computers, some computer heat sinks 
may also contain a fan to help with keeping the processor cool.
You should only expect to hear a slight hum from the CPU fan; below 
are some issues that may cause additional noise from your CPU fan.
- Cable is hitting the fan causing a vibration.
- CPU fan is loose causing vibration
- CPU fan is bad causing additional noise.
- CPU fan is loose causing vibration
- CPU fan is bad causing additional noise.
Power supply fan
See below power supply section.
The computer hard disk drive is a common issue for additional 
noise. It is normal for a hard drive to produce noise. Normal noises you should 
expect to hear include a low humming or quiet whistling sound.
Noises you should not expect to hear are repetitive clicking, very 
noticeable humming, or any hard thump. If any of these noises are experienced it 
is recommend that the hard disk drive be looked at or replaced as it may be 
going bad.
Note: You will notice an increased volume in sound from a SCSI hard 
disk drive when it is compared to a standard IDE/EIDE hard disk drive.
When connecting to the Internet or another computer you may hear a 
loud screechy or high pitched noise. This noise is the onboard modem speaker and 
is the two computers connecting to each other. This noise should only be heard 
when the computer is establishing a connection with the other computer.
The power supply is a common hardware component to cause an 
excessive amount of noise. This component provides your computer power as well 
as ventilation to the computer. It is possible 
for the fan within the power supply to become bad or dirty causing the 
fan to make an excessive amount of noise.
If an excessive amount of noise is coming from the fan next to 
where you plug your computer power cable into, it is likely that the power 
supply fan is failing or bad. We recommend that you first clean the fan by using 
compressed air to blow out any dust, dirt, 
or hair. If this does not resolve your issue you will need to have the power 
supply replaced.
