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

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.
