Troubleshooting Without Diagnostics

Solving Hardware Installation Problems

You may need to reconfigure the computer when you add or remove hardware, such as an

additional diskette drive. If you install a plug and play device, Windows XP automatically

recognize the device and configure the computer. If you install a non–plug and play device, you

must reconfigure the computer after completing installation of the new hardware. In Windows

2000, select the Add New Hardware icon in the Control Panel (for Windows XP, use the Add

Hardware Wizard) and follow the instructions that appear on the screen.

Solving Hardware Installation Problems

Problem Cause Solution

A new device is not

recognized as part of

the

system.

Device is not seated or

connected properly.

Ensure that the device is properly

and securely connected and that

pins in the connector are not

bent

down.

Cable(s) of new

external device are

loose or power cables

are unplugged.

Ensure that all cables are properly

and securely connected and that

pins in the cable or connector are

not bent down.

Power switch of new

external device is not

turned on.

Turn off the computer, turn on the

external device, then turn on the

computer to integrate the device

with the computer system.

When the system

advised you of changes

to the configuration,

you did not accept

them.

Reboot the computer and follow the

instructions for accepting the

changes.

A plug and play board

may not automatically

configure when

added

if the default

configuration conflicts

with other devices.

Use Windows XP Device Manager

to deselect the automatic settings for

the board and choose a basic

configuration that does not cause a

resource conflict. You can also use

Computer Setup to reconfigure or

disable devices to resolve the

resource conflict.

Computer will not start. Wrong memory

modules were used in

the upgrade or memory

modules were installed

in the wrong location.

1. Review the documentation that

came with the system to

determine if you are using the

correct memory modules and to

verify the proper installation.

2. Observe the beeps and LED

lights on the front of the

computer. See

Appendix C,

“POST Error Messages” to

determine possible causes.
