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. For example, beep code 1-3-1 (one possible beep code) 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 correct the following beep code errors. If the problem persists, contact Dell (see
obtaining technical assistance.

1-3-1 through 2-4-4 Memory not being properly identified or used
4-3-1

1. Determine if a conflict exists by removing an expansion card (not a graphics card) and restarting
the computer (see
Removing PCI and PCI Express
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 (see
Software and Hardware
Problems).
4. If the problem persists, contact Dell (see
