A driver acts like a translator between the device and programs that use the device. Every device, whether it be a printer, disk drive, or keyboard, must have a driver program. Many drivers, such as the mouse driver, come with the operating system. For other devices, you may need to load a new driver when you connect the device to your computer.All of the device vendor provides driver for their device, you just need to install the driver. In Windows environments, drivers often have a.DRV extension.

If you’re having a hardware problem that you suspect is caused by a device driver, your first stop should be Device Manager. Open the properties dialog box for the device, and use the following buttons on the Driver tab to perform maintenance tasks:

To do this go to start > Right Click on Computer > and than to Properties.

Click on Device Manager as shown below

Now go to the device that is having problem

 Double click on device having problem, select one of the troubleshooting method according to your need.

Update Driver: This choice starts the Hardware Update wizard.

Roll Back Driver: This option uninstalls the most recently updated driver and rolls back your system configuration to the previously installed driver. Unlike System Restore, this option affects only the selected device. If you have never updated the selected driver,this option is unavailable.

Uninstall: This button completely removes driver files and registry settings for the selected device. This option is available from Safe Mode if you need to remove a driver that is causing blue-screen (Stop) errors. You can also use this capability to remove a driver that you suspect was incorrectly installed and then reinstall the original driver or install an updated driver.
