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:
1
Click the Windows Vista start button, right-click
Computer, and then click Properties.
2
Under Tasks, click Device Manager.
3
Click the plus sign (+) next to the problem device, and check
for exclamation points in a yellow circle near the device icon.
The exclamation point means that there is a device conflict or
a problem with the device. Exclamation points do not always
appear when a device is not working properly.
4
If you have removed a hardware device, and the device
driver is 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.
5
Double-click the name of the device, and then select
Properties.
6
Click the Resources tab to verify that there is a device
conflict.
7
Click the General tab to see whether your device is enabled
and working properly. If it is available, click the
Troubleshoot button, and then follow the onscreen
instructions in the device troubleshooter wizard.
8
Click the Windows Vista start button, click the Arrow
button next to the Lock button, and then click Restart.
