NOTE: See article How to check your system configuration for help identifying Video controllers and other hardware components.

Intel Chipset software

Check if the chipset driver is installed by looking at Device Manager (shown below). Install the Intel chipset update from the www.dell.com/support/drivers website or by inserting the Dell Resource DVD.

Generally, Windows has comprehensive support for many items, but the following Dell-branded drivers and software must be installed for proper operation if the operating system has been removed and reinstalled:

Windows 7>Chipset Drivers>Intel Q45 Express Chipset Software Installation Utility.

The Universal Serial Bus controllers entry is another good spot in Device Manager to verify the chipset driver is installed. The host controllers are identified correctly if the chipset driver is installed.

You can also use System devices to verify the chipset driver is installed. The devices controlled by the 82801 I/O controller hub, DRAM Controller and PCI bus are properly identified when the chipset driver is installed.

Video

The video drivers are sorted into two parts. They are Intel Unified Memory Architecture (UMA) drivers and Add_in card drivers depending on different system specifications.

Add-in card driversThe add-in video card drivers are for the following optional video controllers:

  • ATI Radeon HD3450
