The Device Manager is your link to all things hardware. As shown in Figure 16-7, it lists every component of your PC, and lets you install, uninstall, update, or troubleshoot your device drivers.
To open Device Manager, right-click My Computer and select Manage from the shortcut menu. Double click Device Manager in the left pane to open the device "tree" in the right pane (Figure 16-7). Click a plus sign to see the actual model names for these components that are installed in your PC.
Device Manager lists most of your PC's components, but not all; it may hide non-Plug-and-Play devices, among others. On rare occasions, you may need to see these devices to troubleshoot a problem.
To view hidden devices in Device Manager, choose View→Show Hidden Devices. Repeat the selection to hide them again.
Device Manager can print reports about your system, including a system summary and reports about a particular device or class of device—if you're familiar with IRQs and other resources (see page 344), such a list can be a useful troubleshooting tool. To produce a report, follow these steps:
Open Device Manager.
For a report on a particular device or class of devices, highlight the device in the right pane.
Choose View → Print.
The Print dialog box appears.
Select the type of report you want, then click Print.
