If a red X, yellow ! or yellow ? is displayed to the left of a listed device, a conflict is present and the drivers must be updated or reinstalled. Driver conflicts may also be indicated by a device entry labeled Other Devices or Unknown.
If a conflict is present:
Right-click the device then click Update Driver Software.
Click Browse my computer for driver software.
Enter C:\Windows\System 32\Drivers in the search field then click Next. The driver location can be entered manually or navigated to by clicking Browse. If the driver software is not found, a Windows Operating System update may be needed.
