First, what's a driver?
A driver is software that allows your computer to communicate with a piece of hardware. Your PC consists of many hardware components, such as your hard disk, optical drive (CD or DVD drive), USB card, and video card. All these devices and more require drivers to function.
Doesn't Windows include drivers?
Yes, it does. Windows includes drivers for many common devices. But it may not contain the latest drivers available for your hardware.
Doesn't Windows Automatic Update install the latest drivers?
Sometimes, but not always. This is why you may have to check the website of the maker of the individual components in your PC.
Doesn't the automatic updater from my computer's manufacturer install the latest drivers?
Again, sometimes it will, but sometimes it won't. If you have any questions about installing updated drivers on your computer, contact the manufacturer of your computer.
How do I find out where to get the latest drivers for a particular component in my PC?
Microsoft or your computer's manufacturer may have released updated software. Check to see if there are updates to Windows. Check your computer manufacturer's website for updates, particularly for updates to the CD or DVD drive, graphics card, sound card.
You may need to go to the company that made the component if an update isn't included in Windows or from the computer manufacturer. In this case, the first thing you need to do is find out which company made the component. If you aren't sure whether your Windows-compatible PC or its hardware are update to date, contact your computer manufacture or a local PC computer repair shop.
