Note: Use this page as a reference for what the drivers should look like in Device Manager when installed. Drivers can be downloaded from the Dell Support Site.
Notice: See article ID: sln128938 Checking Hardware Configuration for help identifying Video controllers and other hardware components.
Note: The drivers installation for both Windows 7 and Windows 8.1 are identical. (Most of the device drivers will be pre-installed during the Windows 8.1 installation process.) For best results, we recommend installing the Intel Chipset driver utility first.
