# Troubleshooting: Noise Issues

> CAUTION: Do not attempt to service the system except as explained in the documentation. Only trained service technicians should remove the system cover to access any of the internal components.

Ensure that all components are properly installed and are free from damage, including:

- PCI cards and risers
- Power supplies
- Cooling fans
- System board tray
- CD-ROM and floppy disk drive
- Drive carrier connections to the SCSI backplane board

Also ensure that all cables are properly connected. If you need to replace a component, refer to the instructions in the documentation for your server.
