System Troubleshooting Chapter 5

Troubleshooting Checklists

Use the following checklists to test or verify items.

Problems During Start-up

• Are all connections secure?

• Are the device drivers installed?

• Are the jumpers on any add-in boards correctly positioned?

• Is the hard drive formatted and recognized correctly in the

BIOS?

• Is the RAM memory properly installed? You may want to reinstall

it to ensure a good connection.

• Is the IDE cable from the hard drive properly connected? You

may want to see if the system will boot from a floppy disk.

• Is BIOS properly configured? Select ’Load Optimal Default’ in

the CMOS setup procedure. This will restore the BIOS settings to

the original factory settings.

Problems After Start-up

• If you are running a software package, reinstall the software.

• If the problem is intermittent, you may have a loose connection.

Check all connections including any PCI cards. Check that the

memory module (DIMM) is fully installed.

• Does your system have a computer virus? Run anti-virus

software.

• Try clearing CMOS by removing and reinstalling the battery (on

backplane) and running BIOS Setup.

• Although the computer has a regulated and protected power

supply, a transient voltage in the power line or peripheral cable

may cause a flickering display, unexpected reboots, or a locked

up system. If so, exit the application and start over.

• Is the IDE cable from the hard drive properly connected? You

may want to see if the system will boot from a floppy drive.

• Is the system overheating? Verify that all the fans (CPU, Chassis,

power supply) are working.

• Verify that the ambient air temperature is <50 °C (122 °F).

• Check for proper clearance around the computer to verify

adequate air flow.
