Beep Codes and Error Messages

T
his chapter describes the beep codes and error messages that are common to
all members of the Dell OptiPlex GXa and OptiPlex NX family of computers.
These error messages can occur during the POST or, in the case of some fail-
ures, during normal system operation. The tables in this chapter list faults that
can cause a beep code or system error message to occur and the probable causes
of the fault in each case.
If a faulty system does not emit beep codes or display system error messages to
indicate a failure, you should use the computer diagnostics to run the appropri-
ate tests to help isolate the source of the problem. See "Running Computer
Diagnostics" in Chapter 2.

If the monitor cannot display error messages during the POST, the system may
emit a series of beeps that identifies the problem or that can help you identify a
faulty component or assembly. Table 3-1 lists the beep codes that may be gener-
ated during the POST. Most beep codes indicate a fatal error that prevents the
system from completing the boot routine until the indicated condition is
corrected.
When the system emits a beep code, record the code and then find it in
Table 3-1. If the table does not lead to the source of the problem, run the appro-
priate tests in the computer diagnostics to assist in troubleshooting the problem.
