Why Did My Device Suddenly Stop Working?

August 27th, 2013 No comments

It’s a sad but true fact of life that your printer, scanner, or other computer device is most likely to stop working right at the moment you need it the most. Scrambling to discover why your connected peripherals are no longer recognized by Windows XP can increase your stress when you are already under a heavy workload. To keep your homework assignments or work presentations running smoothly, learn the right ways to troubleshoot issues that cause the computer to report a device not working.


Check For Simple Issues


Always start by double checking that a very simple problem isn’t the culprit. For example, try disconnecting and reconnecting any cables between the device and your computer. Many times a USB plug or printer cable is simply loose and unable to properly communicate between the two pieces of equipment. You may even need a new cable if there is physical damage to the exterior. Try connecting the device to another computer to discover if it is the printer or your operating system. If your scanner or camera simply won’t power up at all, it is unlikely that the problem lies with the drivers or software.


Dealing With Common Problems


Once you are sure that the device itself is still functioning properly, you can proceed to discovering the disconnect between the computer system and the peripheral. In many cases, a simple driver issue is the cause. The files are easy to lose, move, accidentally delete, corrupt, or overwrite. Uninstalling something unfamiliar in your computer’s “Add or Remove Programs” window could lead to speakers that no longer emit sound or a flickering black and white monitor. There are a few basic steps to take to find out if you are experiencing Windows XP driver problems.


 Start With The Device Manager


As with nearly any task involving Windows XP drivers, your work will begin with the Device Manager. Accessories that worked well at some point in the past may or may not show up in this window. If the device driver was not successfully installed in the first place, you should definitely see warning signs. Open this tool by:

  1. Click on the Start menu button at the lower right corner of the screen, then click once on Control Panel.
  2. Double-click on System, then click just once on the Hardware tab. You should now see the Device Manager button, which also needs a click.
  3. The Device Manager window will display all of the devices currently connected to your computer. If they are installed, an accurate listing should be found under the correct categorization. Devices with detected driver issues will display a bright yellow icon with an exclamation point in the center. Look for the device that is not responding and double click on it.
  4. If there was an issue detected, the window that appears may have a button labeled “Reinstall Driver” near the bottom. Clicking it will open the Hardware Wizard, which connects you to Windows Update for automatic driver updates.

 Replacing Missing Or Corrupted Drivers


Checking the database provided by Microsoft for Windows XP may very well solve your problem. Manual installation is also possible. It may be the better option if you have visited the manufacturer’s website and they offered an updated file to deal with issues with previous driver versions. In other cases, you may need to rollback a driver to a previous version if the newest updates introduces issues.


Manual Device Driver Updates


When you are ready to install the latest and greatest update to the drivers, start with the process listed above. Open the Device Manager through the Systems window, then double-click on the device in question and hit “Reinstall Drivers”. Then:

  1. Click on “No, not this time” when the Hardware Update Wizard requests a connection to Windows Update.
  2. Choose the “Install from a list or specific location” option on the next page. Click next.
  3. Use the first option and the subsequent file location browser to point the wizard to the files you have downloaded. Uncheck the “Search removable media” option unless you have the files loaded on a CD or DVD.
  4. Hit Next and let the wizard handle the installation process for you.

Rolling Back Drivers And Restoring Your Settings


It is immensely frustrating when your printer or external hard drive was working just fine yesterday, but it won’t respond today. If you just updated or reinstalled the drivers when the problem occurred, try rolling back to a previous version:

  1. Open the Device Manager with the above instructions. Find the driver you are experiencing issues with and double-click on it.
  2. Select the Driver tab and click on the “Rollback Driver” button. This will allow the computer to search out the previously installed file and use it once again.

Sometimes the older driver files are simply too corrupted or were accidentally deleted, making them impossible to reinstall. You can also try restoring your system to a previous point if you had Windows XP System Restore Points enabled when the device was working. To give this a shot, try:

  1. Start the process in the Administrator profile for the system. Open the Start menu, then navigate through the Accessories menu to find the listing entitled System Tools. Click on this, then click on System Restore.
  2. Selecting the “Restore my computer to an earlier time” option will allow you to bring back deleted system files and restore registry settings that might be interfering with the device.
  3. Choose a save point from a time when you know the device was working properly. Run through the rest of the menus and allow your system to restart.
  4. Check to see if it functions properly again on the newly booted system. If not, use the on-screen prompts to reverse the restore point.

It’s unusual that a device will need a full uninstallation and fresh installation to start running again. In most cases, you can use the steps above to solve driver or registry problems in just a few minutes. Be sure to solve any virus infestations or hard drive errors that might be leading to corruption and damage of your driver files.

Understanding Different Device Manager Error Codes

May 12th, 2012 1 comment

Device Manager error codes pertain specifically to issues in the Device Manager of your computer. These messages are generated when the device that you are trying to access cannot be started or when you encounter issues on the device drivers, hardware problems, or system resource conflicts.

Whenever trying to troubleshoot issues on your computer, make sure that you already know that Device Manager error codes are different from system error codes, even though they both display the same code numbers at times. Whenever you see the error code outside the Device Manager area, then you can breathe a sigh of relief since it is not a Device Manager error code.

If you are unfamiliar with the different kinds of error codes for your computer’s Device Manager, below are some of the code errors you may encounter:

Code 1

‘This device is not configured correctly. (Code 1)’

Code 3 

‘The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3)’

Code 10

‘This device cannot start. (Code 10)’

Code 12

‘This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12)’
Code 14
‘This device cannot work properly until you restart your computer. (Code 14)
Code 16
‘Windows cannot identify all the resources this device uses. (Code 16)’
Code 18

There are different ways of fixing these errors including rebooting your computer, uninstalling the device driver, updating software drivers, or even total replacement of the hardware if needed.Before trying to troubleshoot the issue however, make sure that you have understood exactly what the code error is so that you will not create more problems for your computer.

Dealing With Code 10 Errors

May 2nd, 2012 No comments

There are many Device Manager error codes and this includes Code 10 error, which is displayed as ‘This device cannot start. (Code 10)’, whenever the hardware device you are trying to access cannot be started. Whenever this happens, you can always check the details from the Device Status option from the device properties.

Do keep in mind however, that Device Manager error codes such as Code 10, are specifically for the Device Manager. Whenever it appears elsewhere in your Windows OS, there is the possibility that it is a system error code which you should not consider troubleshooting as one of the Device Manager issues.

What are the causes for the Code 10 Error?

A Code 10 error is generated and displayed whenever your computer’s Device Manager cannot start a specific hardware device due to corrupted or outdated device drivers. This is one of the reasons why it is also important for you to constantly check and download driver updates not only to keep the device functioning properly, but also to enjoy new features offered by the manufacturing company. Although the code 10 error message refers to Device Manager issues, it cannot pinpoint which specific driver or device hardware is having problems.

How to troubleshoot the Code 10 error

1. Restart your PC, since there is a slight chance that the cause of the Code 10 error is due to some temporarily problems in the Device Manager. If this is the case, rebooting your computer may do the trick.

2. If you have installed or updated a device before the Code 10 error appeared, there is the possibility that this has caused the Code 10 error. Solutions include removal or the reconfiguration of the device that you have recently installed, or the use of the roll back device driver or system restore to undo any recent changes you have made on the Device Manager.

3. If the mentioned solutions above fail, you always have the option of re-installing the drivers for your device. Remember however, that this is different from updating the driver since the former process entails the complete removal of the driver and installing it again from the very start.

4. Update the device drivers.

5. Installing the most recent Windows service pack may also resolve the issue.

6. Delete upper and lower filter values in the computer’s registry.

7. If all the solutions suggested above still fail after trying them over and over again, the next best thing that you could do is replace the hardware completely since there is also the possibility that the Code 10 error is coming from the malfunctioning hardware device.

Understanding What The Device Manager Is

April 22nd, 2012 No comments

Updating device drivers is an important step that you need to take if you want to ensure that your computer performs at its best all the time. However, this would be an impossible task if you do not know what a Device Manager is or where you can access it, since this provides an organized view of all available and recognized hardware devices that are installed in your computer.

What is it used for?

The Device Manager is the part in your computer’s OS where you can manage all installed hardware devices on your computer such as the keyboard, mouse, hard disk drives, USB devices, sound cards, and a while lot more. This is also where you can change hardware configuration settings, check the status of a certain device, manage drivers, enable and disable hardware, and even troubleshoot different issues. Basically, the Device Manager is your master list of all hardware devices that your computer recognizes, making it easier for you to access them one by one.

Accessing Device Manager

There are different ways of accessing the Device Manager and this includes accessing it from the Control Panel, through the Command Prompt, or by typing ‘Device Manager’ in the search box.

Using the Device Manager

As mentioned before, the Device Manager is the master list for all hardware devices that are installed in your computer. This is where you can check out their details and change their settings, if needed.

Below are just some of the things that you can do in accessing Device Manager:

  • Reinstall and uninstall Drivers
  • Update device drivers
  • View the status of a hardware device
  • Roll back a driver
  • Enable and disable a device
  • Find and check the version number of a device driver

Device Manager In Windows: How To View A Device’s Status

April 12th, 2012 No comments

Viewing the current status of the hardware in your PC is important to ensure that everything is working properly. Doing this in Windows XP is easy and once you see a yellow exclamation point beside its icon in Device Manager, then you might just have a problem.

Checking the status of different hardware devices can be done by going to the Device Manager and checking out the details available. If there are any problems encountered by your computer, a detailed error code will be displayed, as well as suggestive solutions for troubleshooting the hardware issues you are encountering.

If you are unsure on how to check a device’s status in your computer, below are easy to follow steps on how to do it.

1. Open the Device Manager  from the Windows XP Computer Management utility option. There are still other ways to do so, including typing ‘Device Manager’ in the search box

2. After opening the Device Manager, search for the hardware device you like to check by clicking the [+] icon from major hardware categories.

3. After successfully locating the hardware you would like to check, right click on the text or icon and choose the Properties option, where you can see the device status. This will display the information and current status of your chosen hardware device.

4. If the device is working properly, the status will read:

The device is working properly. If you are having problems with this device, click Troubleshoot to start the troubleshooter.

5. If the device is not working, an error message will state:

Error Message (Code 00) Click Troubleshoot to start the troubleshooter for this device

The reason behind the importance of checking a hardware device’s status every now and then is not only to make sure that it is still working, but also to know whether or not it needs a driver update. By updating its driver, you can ensure that it will work the way you want it too and at the same time, enjoy new features offered by the manufacturing company.

Finding A Driver’s Version Number in Windows XP

April 7th, 2012 No comments

One of the first things that you need to know about device drivers  would be its version number, so that you know whether or not it already needs installation of new updates or not. If you are planning to update a device driver in Windows XP, you need to check the current version number and compare it with the latest version available, because you might have the latest or best version for the hardware already installed on your computer.

If you are unsure on how to check the device driver’s version number, below are easy to follow steps on how you can do it.

1. Open the Device Manager from the Control Panel

2. Locate the device that you are looking for. This could be done by working through the hardware categories and clicking the ‘+’ icon.

3. After successfully locating the device whose version is you are looking for, right click the name or icon and click on its Properties.

4. Click the Driver tab and look for the Driver Version among the other information stated about the driver. Usually, this is located above the big buttons.

Do keep note however, that you should also pay close attention to the Driver Provider as well. This is because it is highly likely that the device driver currently installed on your computer’s system is a default driver that has little value compared to other device drivers.

When downloading device drivers, do remember to make sure that you correctly choose between the 32 bit and 64 bit device drivers since the device won’t work if you downloaded the wrong version.

Using Device Manager in Windows XP To Enable A Device

March 28th, 2012 No comments

If you have any plans of using a hardware for your computer, you must first enable it in the Device Manager so that Windows XP will recognize is at existing. If you fail to enable it on your computer, you cannot assign it its own system resources thus, making it basically useless.

The good thing is, Windows XP can alert users about hardware that are not yet enabled by displaying a red ‘x’ in Device Manager beside the disabled hardware. To enable hardware device from Window XP’s Device Manager, below are easy to follow steps in doing so:

1. Open Device Manager from your computer’s Computer Management utility and locate the hardware device that you are planning to enable. You can navigate through different categories by clicking the [+] icon to see the complete list of hardware devices available.

3. After locating the Device usage option, enable the Use this device option and click OK

4. After doing so, you will notice the red x being removed from the Device Manager window. if a yellow exclamation point replaces it, you would be required to troubleshoot the problem separately. This is because the yellow exclamation point icon is basically to warn you of different issues related to the hardware’s configuration.

If you want to verify if the hardware device is already working properly, you can do so by then, to ensure that all features are updated and so that you can use the device properly.

Troubleshooting CD/DVD Driver Problems for Windows XP

March 10th, 2011 1 comment

Windows XP is one of the most beloved operating systems ever released, still holding on to a significant chunk of the operating system market even after the release of two successors, Windows Vista and Windows 7. However, the old reliable workhorse is beginning to show its age, being unable to run some of the latest games and applications, as well as being left behind in the realm of hardware compatibility.

This is particularly apparent when it comes to the latest CD and DVD drives. Back then, all you had to do was install the hardware onto your PC and your operating system would automatically detect and install the device. This is because Windows XP comes pre-loaded with drivers for such devices, and is able to select the right one for a certain piece of hardware without prompting.

However, as new types and versions of these drives come out, Windows XP’s driver database hasn’t been able to keep up, which is why some people have run into problems getting the operating system to recognize when a new one has been installed. Fortunately, you don’t have to throw out Windows XP just yet.

Here are a few things you can do to get your new CD or DVD drive working:

Update To The Latest Service Pack

First of all, try updating your version of Windows XP, checking to see if it has the latest Service Packs and official updates installed. These patches usually come with new drivers for all sorts of devices in order to keep the OS up to date with the latest hardware on the market. If you’re sporting the latest version of Windows XP and still can’t get your drive detected, then you’ll have to follow a few extra steps.

Check The Device Manager

The first thing to do is to verify if the drive is correctly installed onto your system. If you aren’t certain if the drive is installed properly, then you can look it up on the device manager. To access it, simply click Start, right-click on the My Computer icon, and then click on Properties. Once the Properties dialog is on-screen, click the Hardware tab, and then click the Device Manager button. Look for your drive on the list of installed devices on your computer. If it’s on the list, it should provide a short description of its status, whether it’s in working order, lacks a driver, or is malfunctioning.

Verify That The Drive Is Compatible

The next thing on your to do list is to determine whether or not the drive you have is on Windows XP’s Hardware compatibility list. This list is constantly updated, and can be found at this website. If the drive that you have is on the list, you should be able to download the appropriate driver from that very website. If your brand new drive isn’t on the list yet, then try contacting its manufacturer. They should provide a driver that allows you to use it with Windows XP. If the drive still doesn’t work after getting the appropriate driver from either Windows or the manufacturer, you might want to double-check if the drive itself still works. That way, you might still be able to get a refund or replacement for the device.


Resolving the "Unknown Device" error in Windows XP / 2003

January 17th, 2011 1 comment

For some reason you had to reinstall Windows. Most of the devices attached to the computer were recognized by Windows and the drivers installed automatically. But, when you check the Device Manager to see whether all the drivers are okay, you find a yellow question mark section labeled ‘Other devices’, which is already expanded. Under that, you see a device for which Windows couldn’t install a proper driver.

Sometimes the device is identified correctly, but Windows doesn’t have the correct driver for it. At other times, the device isn’t identified at all and you’d see an "unknown device" listed. Since Windows doesn’t say what the device is, how do you know, what driver you need to download and install? Everyone won’t take the cover off the computer case and inspect. Even if you can, you may be just lazy to open the computer. Still, you may not know what the device could be. What do you do in such a case?

This "Unknown Device" can be seen as a yellow question mark, if you open the Device Manager. There may be more than one device under the question mark.

Most of the time, the device would have a unique ID burned into it. This ID can be used to find information about the device.

How to find this ID?

Open the Device Manager. Open the properties for the "Unknown Device" and then click the ‘Details‘ tab. Select ‘Hardware IDs‘ from the drop-down list. There may be many lines of junk. You only need the first line. It contains all the information needed to find the correct driver.

Taking the following example, VID stands for vendor ID and the number following it is 03E8. Put this into the PCI Vendor and Device List database’s Search box and then click Search. Once you know the device name and manufacturer, you can search a driver for it, download and install it. Here’s a video about using PCI database.

Unknown Device Identifier is a small freeware program from Huntersoft, which identifies unknown devices, not recognized by Windows. It searches working drivers on the Internet and contacts hardware manufacturers or vendors directly.


It comes in handy when you reinstall your operating system and cannot figure out what to do with all those devices with yellow question marks in the device manager.

Unknown Device Identifier is a nice program. It’s easy to use and is a great help to people who need to install drivers for undetected devices on their computers.

Troubleshooting RealTek AC97 Drivers

March 14th, 2010 4 comments

RealTek AC97 Troubleshooting

Audio drivers for your computer can come in many different types depending on the computer  and operating system you are using. One typical audio driver that is often found on many PC  systems is the Realtek AC 97 Audio driver. When there are problems with sound from your PC, you will need to troubleshoot your sound card  to find the cause. This can involve many steps so to help with the process of troubleshooting RealTek on your system we have compiled the following steps:

  1. Check the BIOS settingsThe first thing you need to consider when encountering problems with RealTek AC97 is the settings on the BIOS, especially if the computer is newly-bought. The audio controller for your computer may be disabled. You may also encounter this issue when you have recently reset your BIOS settings to defaults, or when you just upgraded or “flashed” your BIOS.To go to the system BIOS, you need to restart your computer. Then, while the computer is performing some memory tests, press the F2 (or delete) key repeatedly until you see the BIOS screen of your computer. The following image shows how the BIOS screen looks like:

    RealTek Bios Settings

    BIOS utilities may differ in interface and parameters, depending on the manufacturer. The above figure displays an AwardBIOS setup utility. If you there is anything unclear with your BIOS setup, consult your manufacturer’s documentation.

  2. Clean the Prefetch and Temp Folders (Windows only)Some temporary files that your operating system has created may prevent your AC97 driver from functioning correctly. In order to remove those files, you may need to log in to your system in safe mode. To enter safe mode, restart the computer, and while the system is performing memory tests, press F8 repeatedly until you see the Windows Boot Menu. Select either Safe Mode or Safe Mode with Networking in the menu. Note that if you see Windows XP loading without displaying the boot menu first, then your computer will enter in normal mode and not in safe mode. You will need to repeat the procedure all over again, until you have successfully entered the Windows Boot menu and selected safe mode as the boot option.You may need to restart the computer after cleaning the prefetch and temp folders.

    Realtek Safe Mode

  3. Reinstall the Device Driver The reinstallation of a device driver generally involves two steps:
      • Uninstallation of the driver
      • Fresh installation of the driver

    To completely reinstall a driver, the uninstallation of the current driver is necessary. This is to ensure that all driver files will be replaced.

    To uninstall the RealTek AC driver, go to the device manager by clicking on Start and giving a right-click on the My Computer or Computer icon. Then, click on Manage. The Computer Management window would appear. Click on Device Manager and the window would display all the devices installed on your computer. Click on the plus (+) sign before Sound, video and game controllers. Right-click on the AC97 audio controller. Then, click Uninstall.

    RealTek device Manager

    There is another way of going to the device manager. Click on Start->Run. Then, type devmgmt.msc. Press enter and these steps will lead you to the same device manager.

    For a Realtek install, you may use the driver installation CD, download the latest RealTek ac97 driver from the manufacturer, or run a system scan to automatically update the RealTek AC97 Drivers. When installing the driver from the CD, simply insert the CD into your optical drive. You will then given the necessary instructions in installing your device driver.

    Alternatively, a RealTek 97 driver download is available at the Realtek website, or at third-party Realtek download sites. You should be able to find there the correct driver for your operating system, especially a Realtek driver for Windows XP. If the downloaded file is in compressed (ZIP format), you will need to extract the ac97 drivers first. Then, simply run the setup application and follow the installation instructions.

    If the controller is missing in device manager, it means that the driver is not currently installed on your computer. Skip the uninstallation phase and proceed with the installation of the driver. If the controller is followed by a yellow question mark (?) or exclamation point (!), there is a problem with the device driver currently installed on the system, and the instructions in this troubleshooting step must be strictly followed.

    Before uninstalling the Realtek driver AC97, make sure you already have a copy of the driver installation files so you wouldn’t end up with a driverless device. Uninstalling the driver for a device would render that device completely unusable by your computer.

    You will need to restart your computer for the changes to take effect. Restart right after uninstalling the driver, and after reinstalling it.

    Reinstalling a device driver is a lengthy process. If you don’t want to get involved with this procedure for some reason, you may run this automated driver scanner to install the correct driver for your sound card with less effort on your part. This is particularly useful when the driver CD is missing, or you encounter issues with a Realtek download.

  4. Reinstall the Chipset DriversIn some computer systems, chipset drivers also play a part in the performance of your audio device. If you still encounter a problem with the device after installing the driver, you may need to reinstall your computer’s chipset drivers.To reinstall the chipset drivers, simply follow the instructions as mentioned in the previous troubleshooting step (Reinstall the Device Driver). The only difference is that you need to find where the chipset drivers are located in your device manager. They are usually found under Display Adapters.
  5. Download the Latest Updates for Your Operating SystemIf the device is still not working after performing the steps mentioned above, you may need to perform an update on your operating system. Your operating system will usually notify you if there are critical or important updates that would need to be downloaded and installed on your computer. For windows users, you may update your OS by clicking on Start->Control Panel and then selecting Windows Update.
  6. Test another sound cardIf you have reached to this point in troubleshooting and the device is still not working, you may need to test the functionality of your sound card. Remove your sound card and replace it with a similar device that is known to be in good condition. If the newly-installed sound card solves the issue, the other sound card is faulty and may need to be replaced. Otherwise, proceed to the next troubleshooting step.

    If you are using a sound controller integrated into your motherboard, or if there is no alternative sound card available, ignore this troubleshooting step and proceed to the next one.

    Each type of computer has its own architecture. For instructions in removing and installing the sound card for your computer, consult your manufacturer’s or distributor’s documentation.

  7. Reinstall the Entire Operating SystemReinstalling the operating system may not sound good. But if the previous troubleshooting steps did not resolve the issue with the AC97, this procedure may be necessary.

    If this is the first time that you are going to reinstall the operating system, you may need to ask for professional help. Contact one of your computer or operating system manufacturer’s technical support staff for assistance.

    Make sure you backup your important files first before performing this step, since this procedure will wipe out everything in your hard drive.

  8. Flash the BIOSEvery device on your computer has its own driver. But how about the motherboard? The fact is, the BIOS is somewhat the “driver” for your entire motherboard.  It synchronizes almost every hardware installed on your computer system. Flashing the BIOS is similar to updating your operating system e.g. Windows update, etc., except the fact that with this procedure, you are dealing with your BIOS and not with your OS.Before flashing your computer’s BIOS, you will need to determine where your computer system came from. If your computer system is custom-built, visit the manufacturer of your system’s motherboard for the BIOS updater application. If your system is pre-built by computer manufacturers such as Dell, Asus, or HP, visit their website and see if there is an update available.

    Make sure you have performed the previous troubleshooting steps before going on with this procedure. You may skip reinstalling the operating system and do this right away, especially if you do not have the time or the resources needed to install a fresh copy of your OS into your computer. However, this is not advisable. If your BIOS experienced an error during flashing, the process can ruin your motherboard. This is the reason why flashing the BIOS is one of the most feared steps in computer troubleshooting. Should you feel uncomfortable in performing this procedure, you may need to request assistance from professionals.

  9. Replace motherboardProvided that all of the above-mentioned troubleshooting steps have been performed, and the problem still persists, this may mean that your motherboard is unable to handle your AC97 device correctly, and may need to be replaced.
