Dell XPS/Dimension XPS - Manual (Page 3)

Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies
a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer
encountered a memory problem.
Reseating the memory modules may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in your Owner's Manual for
instructions on obtaining technical assistance.
If you hear one of the following beep codes, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.
3. Restart the computer.
4. If the problem persists, see "Contacting Dell" in your Owner's Manual.
Memory modules are detected, but a
memory configuration or compatibility
error exists.
l Ensure that no special memory module/memory connector placement requirements exist.
l Verify that the memory modules that you are installing are compatible with your
computer.
l If the problem persists, see "Contacting Dell" in your Owner's Manual.
A possible system board resource
and/or hardware failure has occurred.
See "Resolving Software and Hardware Incompatibilities" in your Owner's Manual.
If the problem persists, see "Contacting Dell" in your Owner's Manual.
A possible expansion card failure has
occurred.
1. Determine if a conflict exists by removing a card (not a video card) and restarting the
computer.
2. If the problem persists, reinstall the card that you removed, remove a different card, and
then restart the computer.
3. Repeat this process for each card. If the computer starts normally, troubleshoot the last
card removed from the computer for resource conflicts (see "Resolving Software and
Hardware Incompatibilities" in your Owner's Manual).
4. If the problem persists, see "Contacting Dell" in your Owner's Manual.
Another failure has occurred. l Ensure that the cables are properly connected to the system board from the hard drive,
CD drive, and DVD drive.
l If the problem persists, see "Contacting Dell" in your Owner's Manual.
The computer is in a normal operating
