Troubleshooting Tips
Steady
Blue
A possible expansion
card failure has
occurred. 1 Determine if a conflict exists by
removing an expansion card (not a
graphics card) and restarting the
computer (see the "Cards" section for
your computer).
2 If the problem persists, reinstall the
card you removed, then remove a
different card and restart the
computer.
3 Repeat this process for each expansion
card installed. If the computer starts
normally, troubleshoot the last card
removed from the computer for
resource conflicts.
4 If the problem persists, contact Dell
(see "Contacting Dell" on page 66).
Steady
Blue
Another failure has
occurred. • Ensure that all hard drive and optical
drive cables are properly connected to
the system board (see the "System
Board Components" section for your
computer).
• If there is an error message on the
screen identifying a problem with a
device (such as the floppy drive or
hard drive), check the device to make
sure it is functioning properly.
• If the operating system is attempting
to boot from a device (such as the
floppy drive or optical drive), check
system setup to ensure the boot
sequence is correct for the devices
installed on your computer.
• If the problem persists, contact Dell
(see "Contacting Dell" on page 66).
