Understanding Device Drivers

Every device has certain specialized commands that control its functioning. Only the device driver has the knowledge of these commands. The computer interacts with the different devices with the help of these commands. The application programs and operating system of a computer send the commands to these devices. These commands are sent in a high-level programming language. The function of the device driver is to act as a translation medium between the device and the operating system of the computer.

Troubleshooting a device driver

There are varieties of troubleshooting steps depending on the symptoms seen by a user. Some of the troubleshooting steps are explained below.

Computer does not work properly after the installation of a new driver

The computer may start displaying the blue screen error or stop working properly after a new device driver has been installed. The computer may also restart randomly. This problem may also be caused because of the newly installed driver if it is an inferior quality driver. It can also be a result of incompatibility between the driver and the operating system. To solve this problem, remove or uninstall the device driver. After uninstalling the device driver, restart the computer. If the device driver is the cause, the computer may behave properly. In such a case, report the problem to the driver manufacturer. You can also try to obtain the updated version of the driver from the Microsoft Windows update website.

If you update a device driver, the driver file must be updated in the computer memory. This does not happen in some cases. The driver file is updated in the computer memory only after you restart the computer. Additionally, the computer does not prompt you to restart after the installation process is complete. The problem can occur if:

  • You have used the update device driver wizard in the device manager to update the driver.
  • You are updating a driver that is being used by more than one device.
    To overcome this problem, manually restart your computer after you complete the installation of the updated driver.

Unable to download driver updates from the Windows update site:

You can download updates for your device drivers from the windows update site. In some cases, the installation does not succeed.

It is only necessary to check the installed driver files. This causes the above problem. The problem can be solved by getting the latest service packs. A service pack is an update of the software that contains additional features and solutions to bugs in the earlier versions of that software. The service packs help to keep the product up to date. It contains updates, administrative tools and drivers. You can download the service packs for Windows operating system for Microsoft site.
