The path between the operating system (OS) and virtually all hardware not on the computer's motherboard goes through a special program called a driver.
Device drivers are essentially small programs that enable the operating system of your computer to communicate with various hardware devices like mice, keyboards, speakers and disk drives, making them an integral part of a computer system.
For many hardware devices to work on a Windows ( OS) system, they must have the appropriate version of driver installed; otherwise, the operating system will not recognize such devices. Sometimes you may need to update device drivers, find new ones or simply check if the currently installed ones are working properly. Start by finding out what drivers your Windows 7 system is running.
