Click "Start." Right-click "My Computer" and select "Properties" from the context menu. Go to the Hardware tab, then click "Device Manager."
The chipset, integrated into your computer's motherboard, provides pathways of communication between connected hardware and determines what technologies the Compaq Presario V2000 supports. The operating system interfaces with the chipset using a software called a device driver; installing this software enables the OS to provide video, universal serial bus, integrated drive electronics and serial advanced technology attachment support. The OS stores pre-existing drivers to the System32 folder. If Windows is having difficulty interfacing with the above devices, reinstall the chipset driver found in System32. If Windows has failed to install the proprietary drivers for the V2000 chipset -- instead relying on generic drivers to interface with the hardware -- download and install the chipset software from the HP website.
Double-click "System Devices." Right-click each device containing the name of the chipset or the chipset manufacturer, Intel and then click "Uninstall."
Restart the computer; Windows XP will reinstall the chipset drivers for the Compaq Presario V2000 the next time the OS boots.
