How to use Device Manager

The Device Manager utility provides a graphical view of all the hardware installed on the computer along with their associated device drivers and resources. It also acts as a central point to change any hardware settings and update associated device drivers. To access Device Manager on Windows 9x/ME, right-click My Computer and select Properties. Select the Device Manager tab. On Windows 2000/XP, right-click My Computer, select Manage, and click Device
Manager in the left pane.

Device Manager will list all the hardware in the PC in a tree structure. You can view devices by device-type or by connectiontype. In either view, Device Manager will list the devices causing problems. The problem devices will be listed with any of the following symbols:

* A black exclamation mark (!) in a yellow circle means that the device has a problem. Note: A problem-state device could still be working.
* A red “X” means the device is disabled. That is, it is physically present in the computer and is consuming resources, but does not have a driver loaded.
* A blue “i” on a white circle means that the device’s “Use Automatic Settings” feature is not selected for the device, and that the resources were manually allocated, usually for non-Plug and Play devices.
Note: This does not mean that the device is in a problem or disabled state.
* A green question mark (?) in Device Manager means that a compatible (and not the actual) driver for this device is installed, which makes it possible that all the functionality may not be  available.
Note: This applies only to Windows ME.
* A yellow question mark (?) with “Unknown Device” means that Windows has not recognised the device. Once you’ve identified the device(s) with problems, double-click on the device to bring up the property page for the device. The property page or sheet has a General tab that shows the details of the device, and its current status (enabled or disabled). Depending on the type of device, there may be additional tabs such as Resources, Driver and Settings.
