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.
