Troubleshooting from Device Manager is a process by which Microsoft Windows users diagnose and repair problematic hardware or components of their Personal Computer. The Device Manager is a Control Panel applet that gives a graphical view of the hardware installed on a computer. To access the Device Manager in Windows 7, click the Windows icon/start menu, click Control Panel, click System and Maintenance, then click Device Manager. Here you can change the way your hardware is configured or how it interacts with the rest of your computer. Also, you can check the status of your hardware and update the device drivers for your hardware.
Types of icons
Disabled device
A disabled device has either been manually disabled by a user or by some way of error. In Windows 7, this is denoted by a grey downward pointing arrow in the lower right-hand corner of the device's icon, or a red X in some older versions of Microsoft Windows. To enable a device, right-click the device and click Enable.
Hardware not working properly
Hardware may not work properly for a multitude of reasons. If Windows recognizes a problem with a device, it is denoted by a black exclamation point (!) on a yellow triangle in the lower right-hand corner of the device's icon.
Hardware not recognized
Hardware may not be recognized if it is not installed properly or not compatible with your system. This is denoted by a yellow question mark in place of the device's icon.
Device manually selected
A blue "i" on a white field in the lower right-hand corner of a Device's icon indicates that the Use automatic settings feature is not selected for the device and that the resource was manually selected. Note that this does not indicate a problem or disabled state.
