Does the problem appear to be resolved?
Yes. No further steps are necessary.
No. Proceed to the next sections, "Eliminating Resource Conflicts," "Run-
ning the Dell Diagnostics," and "Getting Help."
Devices within or connected to the computer may require dedicated memory
spaces, interrupt levels, or DMA channels, all of which must be allocated dur-
ing installation of the devices. Because devices may be installed at different
times, it is possible that the same resource is assigned to two or more
devices.
Resource conflicts can result in disorderly or erratic system operation or failure
of the system to operate at all. If you suspect that resource conflicts might
exist, check the system using the Microsoft
and reassign the resources as necessary. See "Advanced Expansion Sub-
system" in Chapter 1 for information on the Device Manager. See "Interrupt
Assignments" in Chapter 1 to help identify possible conflicts. Also review the
documentation provided with any installed expansion cards and other devices
for additional interrupt information for the specific devices.
Online troubleshooting tools (OTT), flowcharts, and procedures for diagnosing
problems are available on the Dell World Wide Web site at
http://www.dell.com.
The Dell Diagnostics (included with the computer) contain tests that aid in
troubleshooting all major components of the computer system.

To start the diagnostics, turn off the computer, insert a diagnostics diskette into
drive A, and then turn on the computer.
Starting the diagnostics causes the Dell logo to appear on the screen, followed
by a message indicating that the diagnostics is loading. Before the diagnostics
loads, a program tests the portion of main memory (RAM) required for loading
the diagnostics. If a main memory error is detected, a message appears on the
screen telling you which DIMM has failed.
