Drivers allow the Operating System, e.g. Windows, to access and run the hardware inside your machine.

When you receive an error that a driver is not working correctly, you can usually fix this yourself by searching the internet with keywords similar to model number driver and selecting your operating system. For example, if you use an Nvidia 8800GT graphics card you would search Nvidia 8800GT drivers. Sometimes it can be a bit harder to search and you will need to go and look for it on the manufacturer's website. If you don't know the model number of the hardware then use the manufacturer's website and search through a Drivers or Downloads section.

Once you have obtained the drivers for your operating system, save them to your desktop. In windows, click Start, right click on Computer and select Properties. In Windows 7 / Windows Vista, device manager is usually on the left side. In Windows XP, it is one of the tabs on top. Click on it and you will see a list of all the parts in your PC. Anything that shows an exclamation mark suggests there is a fault somewhere. When you double click it you can see its status and then uninstall the driver in order to install the new one you have downloaded.

If you have any issues, come and see us in the PC Clinic.
