Dell XPS/Dimension XPS Gen 2 - 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.

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.
4. If the problem persists, contact Dell.
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.
