Sleuthing Out Conflicts

When you’re hunting down potential IRQ, memory, and I/O conflicts, try using the Device Manager to help out. Yes, Computer Management, System Information, Hardware Resources, Conflicts Sharing will show you potential conflicts, so that’s a good place to look, too. But let me share a trick with the Device Manager that isn’t readily apparent.

Normally, a class of devices called Hidden Devices isn’t shown. To show them, open the Device Manager (either via Control Panel, System, or from Computer Management). Then, on the View menu, click Show Hidden Devices. A checkmark next to Show Hidden Devices indicates that hidden devices are showing. Click it again to clear the checkmark. Hidden devices include non–Plug and Play devices (devices with earlier Windows 2000 device drivers) and devices that have been physically removed from the computer but have not had their drivers uninstalled.
