Resolving Software and Hardware Incompatibilities

In the Microsoft®Windows®

XP and Windows 2000 operating systems, IRQ conflicts occur if a device either is not detected during the operating system setup

or is detected but incorrectly configured. See the following subsection that corresponds to your operating system to check for IRQ conflicts on your computer.

Windows XP

1. Click the Start button and click Control Panel.

2. Click Performance and Maintenance and click System.

3. Click the Hardware tab and click Device Manager.

4. In the Device Manager list, check for conflicts with the other devices.

Conflicts are indicated by a yellow exclamation point (!) beside the conflicting device or a red X if the device has been disabled.

5. Double-click any conflicting device listed to bring up the Properties window so that you can determine what needs to be reconfigured or removed from

the Device Manager.

6. Resolve these conflicts before checking specific devices.

7. Double-click the malfunctioning device type in the Device Manager list.

8. Double-click the icon for the specific device in the expanded list.

The Properties window appears.

If an IRQ conflict exists, the Device status area in the Properties window reports what other devices are sharing the device's IRQ.

9. Resolve any IRQ conflicts.



You can also use the Windows XP Hardware Troubleshooter. To use the troubleshooter, click the Start button and click Help and Support. Type hardware

troubleshooter in the Search field, and then click the arrow to start the search. Click Hardware Troubleshooter in the Search Results list. In the Hardware

Troubleshooter list, click I need to resolve a hardware conflict on my computer, and then click Next.

See the software documentation — Many software manufacturers maintain websites with information that may help you solve the problem.

Ensure that you properly installed and configured the program. Reinstall the program if necessary.

Turn the computer off — If the computer does not respond to a keystroke or a proper shutdown, press the power button until the computer

turns off. Press the power button again to restart the computer. The solid blue screen appears because you were not able to perform a

proper Windows®shutdown. ScanDisk automatically runs during the start-up process. Follow the instructions on the screen.

Confirm that the problem is software-related — Run the System Board Devices tests as described in "Dell Diagnostics." If all tests in the

device group run successfully, the problem may be software-related. See the software documentation.
