Device Driver Problems

Many computer users are blissfully unaware of the existence of device drivers - at least until something goes wrong.  While most of the time these tiny little files work as they are intended - relaying information and instructions between the computer’s operating system and the connected hardware, occasionally problems do arise.  These problems can be due to a number of causes, including having the wrong device driver installed, having a corrupted device driver or having a device driver that is outdated.

No matter what the cause it is important for computer users to be able to recognize some of the possible signs and symptoms of device driver problems.  If your computer has been experiencing any of these symptoms it may be time to start looking for updated device drivers.  In many cases the symptoms themselves will tell you which device is misbehaving, making it easier to find the right device driver to resolve the issue.

Error Messages

While the error messages provided by Windows can be vague to say the least, they may be able to give you some clues as to which device is causing the problem.  If the error messages appear when you attach or power on a specific piece of hardware the device driver associated with that hardware may be corrupt or outdated.

Frequent Crashes

The causes of computer crashes can be notoriously difficult to pin down, but in some cases outdated, missing or corrupt device drivers can cause these problems.  Device drivers are more likely to be the culprit when the crashes are consistent - always occurring when a particular piece of hardware is in use for instance.

Poor Audio Quality

If your speakers are producing more noise than music your audio card drivers may be to blame. . Frequent pops, crackles and other extraneous noises can be symptoms of corrupt or outdated audio drivers.  If you notice these problems head over to the audio card manufacturer’s website to see if updated drivers are available.

Flashes and Poor Color Quality

Flashing, dimming and poor color quality can be symptoms of missing, corrupt or outdated video drivers.  If you notice any of these symptoms it is a good idea to check the manufacturer’s website for updated drivers.  If the driver for the video card has failed completely you may even see your computer’s display revert to that ugly 16 color state.

Sudden Problems After New Hardware is Installed

If you start to see problems like crashing and poor performance right after a piece of new hardware has been installed device drivers are most likely to blame.  In some cases the problem may be that the device driver is corrupt, while in other cases the driver may be conflicting with existing hardware or software.  In other cases the device driver may already be outdated, even if the hardware has just been installed.  If you start to see problems following the installation of new hardware it is important to head over to the manufacturer’s website.  In some cases the source of the problem will already have been identified and corrected with the release of a brand new device driver.  Downloading the updated driver may solve the problem and allow the new hardware to function as intended.

Just another bad driver

If you notice any of these signs and symptoms a bad device driver could very well be the culprit.  Keeping your drivers up to date can help fend off these problems before they start, so it is important to review those drivers periodically in order to keep your system operating smoothly and efficiently.

Should I be wary of Drivers?

Although no inherent dangers are attached to device drivers, the opportunity does exist for complications to arise to the functioning of your computer and the hardware attached to it. What could be more frustrating than installing a new hardware peripheral along with its driver only to have it fail to perform its task?

You are quite sure that you have installed the driver properly and yet, you receive the warning that the device cannot be detected. Should this make you immediately suspicious of the driver? Should you wonder if the driver that you installed is faulty in some way? Or perhaps, you should suspect that there is something inherently wrong with the driver that you have installed. After all, you know that you have installed the driver that came with the hardware, so of course you are going to wonder why it isn’t working.

In some cases, the difficulty lies not in the device driver, but it lies in the compatibility of the driver with other programs that have been installed on that specific computer. In fact, this is the reason why you receive the message that the computer cannot locate the device itself. The driver is not functioning correctly due to glitches in its ability to get along with all of the many other drivers and programs on your computer.

In fact, the operating system might attempt to communicate to the hardware, but the driver is not able to communicate with the operating system. Hence, you receive the message that your device has not been identified. Typically, this is due to the installation of an incorrect driver.

Additionally, a faulty installation of the driver can lead to a lack of service. If the driver has not been fully installed, then it cannot perform its task correctly. When this occurs, a simple reinstallation or even an updated version of the driver can alleviate that specific situation.

Unfortunately, one of the easiest ways to develop a wariness of device drivers is to install one that has been piggybacked with a computer virus. Since viruses become embedded in files of many types, the possibility does exist. Obtaining your device driver from a reputable source such as the manufacturer’s installation disk for the device or the manufacturer’s website is the most reliable way to ensure that no viruses are attached to it.

Should I be paying for drivers or are they usually free?

I’ve heard it said that the best things in life are free. Whether that is true or not, your device driver should be free. After all, the hardware only functions properly if the driver has been installed for it. This is the main reason that every single piece of hardware has been designed with its own driver in tow.

In fact, whenever you purchase a new piece of equipment for your computer, it should come with a specific driver that has been designed to offer proper functionality.

Typically, the device drivers that your hardware requires are included with the hardware. In respect to Plug-and Play devices, the operating system of your computer will automatically recognize the hardware and locate the necessary driver. With other types of hardware, the drivers are typically included on the installation disk. No separate charges are applied for this. Additionally, the restore disk usually includes the device driver as well.

Moreover, the manufacturer of most hardware devices usually provide driver updates free of charge on their website. As technology advances to implement important changes, so do the device drivers associated with hardware devices. These are usually easy to locate.

Most computer operating systems such as Windows provide a number of generic drivers for a variety of hardware devices. Since they are included with the operating system, obviously they are free to use. While generic drivers are not as functional as the driver that has been designed specifically for a particular hardware device, they are nonetheless free.

When obtaining a device driver, select the newest version in order to obtain the most recent changes. Updated drivers provide the best compatibility with the operating system and other installed hardware. Most manufacturers maintain a support area that provides free help with locating the drivers that you need for your hardware including any updates.

Is the Device Driver the same as a file extension?

Device drivers act as operating system services. While the term itself, device driver, might seem intimidating to anyone who is unfamiliar with computer terminology, you shouldn’t allow it to confuse or upset you. At the very core of the device driver is a file that is essential to its task. Basically, device drivers are programs that allow the computer to interact with its hardware by helping it to translate the specific commands necessary for the hardware to function properly.

Each device driver links against specific libraries within the computer in order to function. In DOS systems, the device driver is a type of file that includes a.SYS extension. In a Windows system, the device driver might include a.DRV extension. File extensions actually provide information about the kind of file it is. The file extension is used to name the specific device driver.

For example, a .doc indicates that the file is a document text file. A .dll indicates that it is a dynamic link library file. A .drv indicates that the file is a device driver. Device drivers are designed to relay information between the computer’s operating system and a specific type of hardware so that the hardware device will function properly.
Each driver file can contain additional file extensions such as a .exe, .dll, or other types of file extension. You can think of file extensions as add ons or additional parts of the whole. Each one will have its own specific task and together they create the whole.

In fact, some file extensions are capable of being shared among a number of different programs. Typically, no problems arise from this unless a shared file is unwittingly deleted from the computer. If this is the case, then computer errors will begin to appear on your machine.

How many kinds of Device Drivers are there?

A diverse lot of device drivers is available simply because of the diversity of hardware devices. When a device driver is written, it is done using the information about the target device including the specific model number and manufacturer of the device. Additionally, the operating system must also be taken into consideration.

Therefore, this leads to a wide array of devices, each of which is specific to a particular piece of computer equipment such as a keyboard, mouse, monitor, sound card, scanner, printer, modem, as well as any number of other hardware peripherals that a computer might be connected to. As technology advances creating an even greater number of electronic and digital devices that can be attached to our computers, an even greater number of device drivers are also created. Therefore, for each MP3 player, video camera, digital camera, iPod, and USB device, a driver is also created.

Each piece of equipment is designed quite specifically by the manufacture in order for it to function properly; it requires a specific device driver that has been designed to recognize its needs and specifications for functioning properly. Therefore, while device drivers for similar pieces of hardware might share many aspects, each has been individualized to take into consideration the specific features of the device for which it has been created.

Additionally, due to the vast number of generic drivers, there is a greater quantity of device drivers above and beyond the number of individual hardware equipment. As least as many different types of device drivers exist as there are types of computer hardware.

Each device driver is set up with commands that are pertinent to the specific hardware as well as the specific device driver. Although the driver might initiate an action by first intercepting a generic command, the command is then translated to one that is specific to the device.
