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.

Help: The Sound on my Computer is not Working

April 21st, 2010 4 comments

The Sound on my computer is not working. What should I do?

OR

I can’t hear any sounds from the speakers or play any music on my computer. What is the problem?

There can be more than one reason, why the computer can’t play any sounds. These are discussed below.

If you have a desktop computer, it may or may not have a separate sound card. But in case of laptops, the sound card is integrated into the motherboard and cannot be removed, so some of the solutions may not apply to laptops.  Also, laptops come with built-in speakers, so the external speakers and cabling problems may not apply here, unless you use external speakers or headphones.

So, where do you start, when you can’t hear any sounds from your computer? Try the steps given below, one by one.

1. Reboot the computer

Before we start with the solutions, did you try the simplest solution first? Rebooting or restarting the computer is the simplest solution and should be tried first. If you didn’t already reboot, try it now. The sounds may just work after a reboot.

2. Enable the System Sounds

Can you hear the Windows startup sounds from the computer? If you can hear the Windows startup and shutdown sounds, the sound card is working fine. If you can’t hear any startup sounds, enable the System Sounds from the Control Panel, if they are disabled.

Enable_System_Sounds
Enable System Sounds. (Click for a larger image)

If you aren’t able to enable the system sounds and they are grayed out, you may need to reinstall the sound driver.

3. Is the problem only with an audio CD?

Are you trying to play an audio CD, and not getting any sound? If you can hear the System Sounds, but can’t hear anything from the audio CD, even though your audio player software shows that it’s playing the disc, the problem is most likely with the digital cable (see image 1 below) that goes from the CD/DVD drive to the sound card (image 2 below) (or to the motherboard).

One side of this cable goes into the back of the CD/DVD drive and the other goes into the sound card or on to the motherboard (in case of motherboards with built-in sound).

4. Are the speakers properly connected?

Are the speakers connected to the proper sound port / jack, at the back of the computer? Are they powered ON? External speakers generally have a separate power adapter, which plugs into the wall socket or any other power source. Is the speaker volume control, set to a comfortable level? If not, turn it to the middle position.

If in doubt, test your speakers by connecting them to another sound device like CD/DVD player or a radio/tape player, or any sound source. If you can hear sounds from the speakers, they are fine.

Check that the speaker pin is connected to the green jack at the back of the computer.

Also, check that the sound (check speaker icon in the system tray) isn’t muted. Such a simple thing, which can happen accidentally, can confuse some people when they can’t hear sounds from their computers. This can get overlooked because the speaker icon may be lost between many other icons.  Click it and un-mute the sound, if it’s muted.

Note: If you can’t see the speaker icon in the system tray, you may need to enable it from the Control Panel. From the Control Panel, double-click "Sound and Audio Devices" and check the box that says "Place volume icon in the taskbar" and click OK.

5. Test with a pair of headphones

Try plugging in a pair of headphones in place of the speakers, to check whether you can hear anything. Play a song or music CD or any sound file, which you may have on the computer. If you don’t have one handy, you can run a command to test your sound:

Click the Start button, and then click Run (or Search, in Windows 7 / Vista). Type the following command and then press the Enter key:

dxdiag

DirectX_Diagnostic_Tool
DirectX Diagnostic Tool

If you can’t see the name of the sound driver, or aren’t able to hear the sound by using the ‘Test DirectSound’ button, or you get an error, the problem may be with the sound driver. Reinstall the sound driver.

6. Try doing a System Restore

If the sound worked sometime ago and now it isn’t working for some reason, the simplest solution for re-installing the sound driver is to do a System Restore. Restore the system to a date that you know, when your sound worked. Check out the following links for a YouTube video and short tutorials on System Restore.

Note: Current documents, files and e-mails are not affected by System Restore. If you get an error like “Restoration Incomplete. Your computer cannot be restored", undo the last action by selecting “Undo my last restoration”. If you restored the system recently, the “Undo my last restoration” option is displayed in the System Restore list. You can use it to undo your most recent restore. This option is available only after you do a restore.

Here’s a YouTube video on how to restore a system with System Restore.

For Windows 7 or Vista:

http://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/

http://www.vistax64.com/tutorials/76905-system-restore-how.html

7. Manually, diagnose the sound driver

If System Restore didn’t help or you get a message that System Restore couldn’t be completed, try the following:

Start the Device Manager (Start -> Run -> devmgmt.msc and hit the Enter key).  In Device Manager, Click the + sign next to "Sound, video and game controllers". See that the sound driver that you noted from dxdiag above, is listed.

Double-click this sound driver. Device Manager should give a status message that the driver is working fine. If the driver isn’t there or if it shows a yellow exclamation mark, shows under other devices, or gives any other kind of status message, or there’s no sound driver at all, reinstall the driver. In any case, it doesn’t harm to reinstall the sound driver.

From this sound driver properties page, you may also click the Troubleshoot button, to open the Sound Troubleshooter in the Windows Help and Support Center.

8. Enable/disable the built-in sound support in the BIOS

If your motherboard has built-in sound support, make sure that it’s enabled in the System BIOS/CMOS. However, if you have a separate sound card, and your motherboard’s built-in sound is also enabled in the BIOS/CMOS, there can be a conflict between the two sound cards. In this case, disable the built-in sound support from the BIOS/CMOS, if it’s not already disabled.

9. Reinstall Windows

If your motherboard’s built-in sound isn’t working, even after re-installing the sound driver, doing a System Restore, you can try reinstalling Windows.

Here are some YouTube videos about how to re-install Windows:

If you have to re-install Windows, you may want to backup any critical data files on to CD/DVD discs or USB flash drives/portable hard drives, before starting the installation. Click here to search for prices on flash drives and here for portable (external) hard drives.

10. Add a separate sound card

If your motherboard’s built-in sound isn’t working, even after re-installing the sound driver, doing a System Restore and re-installing Windows, you need to add a separate sound card. The easy option for non-technical people is to get a USB sound card. Such a card is also helpful, if your motherboard has no free expansion slots for an add-on sound card.

What are USB Sound Cards? USB sound "cards" are actually external boxes that plug into the computer via USB. The sound is produced in the software which runs on the  computer. These boxes only provide for connectivity from the pc via the USB bus to an external device like a microphone or line in/out connector. It’s more appropriate to call them as audio interfaces.

11. Update the sound driver

Here’s an easy way to download and install/update your sound card driver.

12. Inspect the sound card

If updating the drivers didn’t help and if you have a separate sound card (not a built-in one on the motherboard), it’s possible that the drivers are correctly installed, but the sound card was displaced a little bit from its slot. This may be because there’s no screw holding it, or the card’s face plate misaligned with the computer case, which caused a loose contact between the card and the slot.

If you suspect this, you should power the computer off, unplug the power cord from the wall outlet, open up the computer and pull out the card. Then, re-insert it firmly into the slot or insert it into another slot, if you have another one free. Make sure to tighten the screw, which fixes the card to the case, and put one there, if it’s missing. Here’s a YouTube video about installing a sound card.

13. Test the sound card with a Linux Live CD distro

If none of the above methods worked, power off, unplug and open up the computer. Then, pull out your sound card and test it in another computer.

You can also download and boot from an Ubuntu Linux disc (about 700 MB), or the very light DamnSmallLinux (50 MB only), just to test the card, in case you can’t test your card in another computer.

You’d need to burn the ISO file with the “burn image to disc” option, in your CD writing software. To know more, how to burn ISO files, visit this post.

14. Downgrade to Vista or XP, if using Windows 7

If you tested your sound card and it worked with another system, and you have Windows 7 on your computer, it’s most likely that Windows 7 doesn’t support your sound card yet. Here, you have two options – downgrade to Windows Vista or XP, or get a sound card which is supported by Windows 7.

Here’s a list of Windows 7 supported sound cards from Microsoft.

This page lists Windows 7 compatible hardware and software.

Check the compatibility status of your software and devices, here.

If the card didn’t work even with another system, try

another sound card.

15. Test by using a different USB port

If the card is a USB sound card, try connecting it to a different USB port, especially the ones at the back of the computer, if you tried only the front USB ports. If you can’t get the card to work, try it on another computer. If it works on the other computer, the problem may be with the USB ports on your computer.

Test your USB ports by connecting other USB devices. You may also try removing the USB drivers from the Device manager and let Windows re-install them upon reboot. If  your computer doesn’t recognize any USB device, try the solutions in Troubleshooting USB connections”.

CD drive or DVD drive is missing in Windows XP

February 23rd, 2010 2 comments

Q. Help, my CD drive or DVD drive is missing?

A. I am taking this to mean your CD/DVD drive is not recognized, so you can’t play a CD or DVD.

You probably have either corrupted or deleted Windows registry entries. To solve this problem, you need to use the Registry Editor. ***Note: By using Registry Editor, you are modifying the registry. Serious problems might occur if you modify the registry incorrectly. Make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. For more information about how to back up and restore the registry, click here to read the article in the Microsoft Knowledge Base.

  1. Click Start, and then click Run.
  2. In the Open box, type regedit, and then click OK.
  3. In the navigation pane, locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
  4. In the right pane, click UpperFilters.
    *** Note – You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 7.
  5. On the Edit menu, click Delete.
  6. When you are prompted to confirm the deletion, click Yes.
  7. In the right pane, click LowerFilters.
    *** Note – If you do not see the LowerFilters registry entry, unfortunately this content cannot help you any further. Try contacting Microsoft for additional support.
  8. On the Edit menu, click Delete.
  9. When you are prompted to confirm the deletion, click Yes.
  10. Exit Registry Editor.
  11. Restart the computer.
  12. Click Start, click My Computer, and then see whether the drive is listed.

If you still can’t play or access a CD or DVD at this point, next try to reinstall the programs. If that doesn’t work, check to see if there are updates available at the manufacturer’s website. Some examples of programs that might be affected are:

  • iTunes software by Apple
  • Nero software by Nero Inc
  • Roxio Creator software by Sonic Solutions
  • Zune software by Microsoft

Additionally, you  can try to remove and reinstall the device drivers.

Do the following to remove and reinstall the device drivers:

  1. Click Start, and then click Control Panel.
  2. Click System and Maintenance, and then click System,
  3. On the Hardware tab, click Device Manager. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
  4. In Device Manager, expand DVD/CD-ROM drives, right-click the CD and DVD devices, and then click Uninstall.
  5. When you are prompted to confirm that you want to remove the device, click OK.
  6. Restart the computer.

After the computer restarts, the drivers should be automatically installed.
