Hardware installation (continued)

Symptom

A device does not work after installing a new device.

Possible solution

To resolve a device conflict, you may need to disable one of the devices or uninstall an old device driver:

1Click the Start button.

2Type Device Manager into the Start Search box, and then click Device Manager to open the Device Manager window.

3Click the plus sign (+) next to the problem device and check for an exclamation point in a yellow circle near the device icon. The exclamation point means there is a device conflict or problem with the device. Exclamation points do not always appear when a device is not working properly.

4If you have removed a hardware device, but the device driver is still listed in the Device Manager, this may be causing the device conflict. To uninstall the old driver so that the new device driver works properly, right-click the device, click Uninstall, and then click OK.

5Right-click the name of the device, and then select Properties.

6Click the General tab to see whether your device is enabled and working properly. If it is available, click the Troubleshoot button, and follow the onscreen instructions in the device troubleshooter wizard.

7Restart the computer. Click the Start button, click the Arrow button next to Shut Down, and then click Restart.
