    Lightbulb What are Device Drivers?

    Attachment 2529

    When you have your computer reinstalled, chances are you could have many problems such as audio is not working, display quality becomes primitively poor, internet connection drops occasionally, and even worse- your keyboard and mouse simply donít follow your instructions! When it comes to these situations, itís probably that your device drivers are not properly installed.

    But wait, WHAT IS A DEVICE DRIVER?

    It appears that quite a large amount of computer users do not know device driver at all. In this article, Iím going to break down some facts and basics about it, and youíll understand what a fundamental role that device drivers play in your computer.

    First, you know that your computer is made up with various visible components (ie. cpu, memory stick, hard disk, peripherals). But they cannot work without the invisible operating system, which acts like a general commander and tells them what actions to take in order to accomplish tasks for you. However, devices and operating system cannot communicate with each other directly. Drivers are therefore created to help them understand each other. Drivers work like translators and liaisons to convey operating systemís meaning into different languages that different devices can comprehend, without which, devices cannot receive instructions from operating system and accordingly cannot function properly at all.

    However, some devices, such as CPU, memory stick, monitor, keyboard and mouse, seem to be able to work directly without asking us to install drivers for them. This is because these devices are must-have components for a computer to work in basic function. So codes were built in BIOS (software that is loaded immediately when a PC is powered on) at early stage so that they could be supported directly by operating system. Other than that, most devices (like graphic card, audio card, network card) require a specific driver being installed to work properly. You may notice that when you connect a scanner, camera, printer to your computer, youíre always asked to install a certain driver first.

    To have drivers installed is not yet done, it is also important to keep them up-to-date. Drivers are mostly released by official device manufacturers, who keep updating them not only to ensure the best compatibility with different operating system, but also for enhanced performance of devices. Nvidia, for example, a noted brand for graphics chips, averagely upgrade video card driver 2-3 times every month. By installing updated drivers, you will usually get better performance and new features out of your devices.

    Manually
    Right Click "Computer" or "My Computer" on your desktop, click "Manager", "Device Manager", choose a device, right click to "Update Driver Software..."

    Automatically
    Update those outdated drivers automatically with a tool, for example driver booster, driver scanner.

    I don't think the latest drivers are good for my old 2004 PC.

    A good rule of thumb.....if you don't know what you're doing, then don't.

    If your computer is working, don't futz with the drivers. You can do more damage than good.

    It is a program that determines how a computer will communicate with a peripheral device. Nice discuss.

    A device driver is a program that controls a particular type of device that is attached to your computer. There are device drivers for printers, displays, CD-ROM readers, diskette drives, and so on. When you buy an operating system, many device drivers are built into the product. To update device drivers, there are certain ways to follow. First, you can use Windows update.
    Step 1. Swipe in from the right edge of the screen, tap "Settings", and then tap "Change PC settings". But if you are using a mouse, point to the lower-right corner of the screen and move the mouse pointer up. Then click "Settings" and "Change PC settings".

    Step 2. Tap or click "update and recovery", and then tap or click "Windows Update".

    Step 3. Tap or click "Choose how updates get installed".

    Step 4. Under important updates, choose "Install updates automatically".

    If it does not help, you can use a drivers update utility to update the driver automatically. With it, you can download and update whatever drivers whenever in need. tiny.cc/mawerx. It helps me download and update many of my device drivers and I hope it can also work for you. You can download and install it, then it will automatically scan for your system and recommend suitable drivers for you. You can download or update whichever driver you need.

    It's not necessary or appropriate, to post to threads that have not been touched in a year or more.
    In many cases the poster is not even on this forum anymore.
    Doing that to increase your post count can get you banned.
