Dell computers tend to be hardy, requiring a minimum of maintenance. Components -- such as random-access memory, or the RAM card connected to your computer's motherboard -- occasionally fail. Such failures can generate an error code, cause the computer to emit POST (Power On Self Test) beeps, or even prevent the computer from powering up. Rather than immediately sending your computer off for repair, you can save time and money by checking the problem yourself.
Instructions
1. Browse to Dell's Support Website.
2. Click on "Troubleshooting" under "Product Support" on the left menu.
3. Select the computer either by entering the service tag or choosing the model from a list.
4. Click on "Manuals & Documentation" on the right side of the center tabs.
5. Open the service manual with "View," or use "Download" to copy the manual to the computer you're using, and open the manual. Browse to the section labeled "Advanced Troubleshooting" or "System Codes."
6. Compare the lights on the back of the computer (when plugged in) with the list. Follow any instructions given.
If, for example, it says to reseat the memory modules, remove the RAM and reinstall it on the motherboard. (Cleaning the connections can help.) If you continue to get the same error, try replacing a single stick of RAM in the uppermost slot while leaving the rest out.
7. Count the series of beeps when the computer starts, then compare that series with the "POST Beep Codes" in the service manual. Most of these error messages suggest contacting technical support.
8. Copy down and find the error message shown under "System Messages" if necessary.
9. Contact Dell's technical support if all else fails.
