It sounds as though you might have any one of several problems. You might have a corrupted file and need to clean the registry. Quite possibly, the drivers for the device that is generating the message could be in need of an update or replacement. If you have recently updated any drivers, software, or added any hardware devices, this could also be the problem. From what I have read, others have encountered this problem when using Windows Vista operating system and a Lexmark Printer.

Boot up in Safe Mode

The strategy of booting up in safe mode uses the least amount of drivers, so it is your best option for getting things going. If the message “device monitor stopped working” does not appear and the computer is working properly once you boot up, then you can try any of the following options in order to fix the problem permanently.

Run chkdsk

In order to rectify any disk errors that might be creating this problem, you should run the chkdsk utility. This will check for problems related to cross-linked files, lost clusters, directory errors, and bad sectors.

Follow this path: Click “Start”→ click “Run”→ Type “cmd”→ press “enter”. At the prompt, type in “chkdsk volume:/r” in order to recover readable information, locate bad sectors, and repair errors.

Repair and Restore the Windows Vista Operating System

If your operating system happens to be Windows Vista, consider repairing and restoring the operating system. For detailed instructions on how to do so, read the article found at this link: Microsoft936212. This strategy will scan and replace system files that might have become lost or damaged.

Clean the Registry

In case your registry files are severely damaged, I suggest using a reliable application such as RegCure to find and repair them.

Uninstalling the Last Hardware Device Added

If you recently installed some type of hardware device prior to the problem’s occurrence, you should uninstall it completely. If the problem is resolved, then you can safely assume that some type of incompatibility exists between this hardware device and your operating system. Contact the manufacturer of the device for tips and suggestions as they might be able to offer a specific solution.

I think you’re right - somehow your device driver got deleted. Luckily, it is pretty easy to get it back. First, check any cables from your CD-ROM drive to make sure nothing is loose. A loose cable can cause the system to not see the drive.

Search for New Hardware

Sometimes you can get the system to “see” the drive through the Control Panel.

1. Go to Start and then Settings (if needed) and Control Panel.
2. Choose Add/Remove Hardware.
3. Select “Search for New Hardware”.

Reboot your system and see if your computer will now see the CDs. If not, continue on to the next steps.

Find the CD Manufacturer

Drivers are low-level programs that handle the data connection between the hardware and the computer. The first thing you have to do is find out who made the CD-ROM drive that is in your computer. Follow these steps to find the right manufacturer:

1. Go to Start and then My Computer.
2. Scroll down until you see the DVD/CD Rom. Right click on it and then choose the Hardware tab.
3. From here, you should be able to see the properties of the device including the manufacturer or click on the Troubleshoot button to see if the system can fix it.

Download the CD Drive Driver

Now that you know who made the CD drive, you need to find the website and download the driver. Let’s say you find that you have a Pioneer CD drive. Use a search engine to find the Pioneer Web site and browse the Support section in search of device drivers for your exact model and operating system.

Download Sound Drivers

If your CD drive works fine, but sound doesn’t play, you may need to update the sound card drivers instead. For example, if you have a RealTek audio device, you can either Google RealTek audio driver to find a website that has it for download, or go directly to the RealTek website and find the driver to download. Most audio device manufacturers have download buttons that are easily found on their websites. Click on the download button and either save the driver to your desktop or to the correct file. Once you have successfully downloaded the driver, you need to reboot the computer in order for it to be recognized by the system.

Driver Detective and Driver Genius

If you have a problem with your drivers frequently or just don’t want to have to manually find and download missing drivers, you can use a program like Driver Detective or Driver Genius. These programs will manage your drivers on Windows XP and Vista so that you can easily download the right drivers for your devices.

My only question here is if you are getting any sound at all from websites, not just CDs. If you are getting sound from the Internet, then the problem is indeed with your CD-ROM and finding and downloading your CD drivers should solve your sound issues and have you up and listening in no time. If you have no sound at all, the problem may be with your sound card driver. Follow the steps above to find the sound card manufacturer and download the driver in the same way.

Reinstalling an Internal DVD Drive

Adjusting Your IDE Cables

Assuming for the moment that you are connecting, or attempting to connect your old Sony internal DVD drive with an IDE cable, you might need to adjust the master/slave designations to run both drives, or to switch from the LG to the Sony drive. Start by checking the IDE cables, undo and swap them to see if that helps. Also make sure that the DVD player is set to master. You might need to reboot your computer in order for these changes to take effect.

Designating Your Drive Letters

You might need to set a drive letter, or change the existing drive letters of your drives, depending on whether or not you are attempting to keep the LG drive in addition to the Sony drive. To change drive designations you will need to be logged on to your system with administrative capacity. Hit the Start button, and then choose Control Panel, and then Performance and Maintenance. If you run Windows in Classic View, you will need to choose Administrative Tools, then Computer Management, and then Disk Management. From there, you can now change the designated drive letters by right clicking on the drive or device. You should try setting the LG drive to Z, and the Sony back to E to see if the computer prefers to recognize it that way.

Uninstall and Reinstall Your Drivers

To force your computer to recognize the DVD drive you might try uninstalling and reinstalling the DVD drivers. To do this you will want to start your computer in Safe Mode. Power your computer down, wait for about 30 seconds, and then turn it back on, pressing F8 while it boots to get to the startup menu. If you receive a keyboard error, turn the computer off and try again, waiting slightly longer before you start pressing F8. From the startup menu, select Safe Mode.

Next, right click on the My Computer icon, choose Properties, then Hardware, then Device Manager. Now you will see a list of your external devices. Beside the listing for your CD/DVD drive there is a box marked with either a (-) or a (+). Click the (+) for a full list. Now, if you right click on each listing, you will see a drop down menu. From this menu choose uninstall. Once the device is uninstalled you can then repeat these same steps to reinstall the drivers. You might also check the Sony website for updated drivers for your DVD drive.

Your computer thoughtfully generates error codes that will tell you what is wrong with it and often, the best way to fix the problem. Error code 10 means that you need to reinstall the device driver for the hardware that is having the problem. Luckily, this is pretty easy to do.

Find and Uninstall the Device

You need to find the device manufacturer and then uninstall it. Many times, you can just update the driver without uninstalling it, but as long as you’re there, you might as well take it off so that you have a clean install of the new one.

1. Go to Start and then Settings (or just go to Control Panel).
2. Choose Control Panel.
3. Double click on System. Choose Device Manager.
4. Double click on the device type - in your case you already know it is the CD ROM.
5. Double click on the device. You will see the properties for the device and probably the error code.
6. Note the manufacturer. Right click it to uninstall.

Get the New Driver

Now that you know who manufactured your driver, go to the website and download a new one. It is usually pretty easy to find a device driver tab on any website. Find the download tab, push it and let it run. You can either download it directly to the correct file on your computer, or to your desktop and install it later.

Driver Genuis

If you don’t want to go through the trouble of finding and installing drivers manually, you can use a program called Driver Genius to do the work for you. It will manage your drivers so that you can download the proper drivers for your devices.

Once you’ve installed the right driver, your CD ROM should work just fine.

Normally, I’d tell you to go to the Sabrent website and find the correct driver to download, but in researching your question, I found that they no longer have the drivers on their site. Even though the manufacturer doesn’t support the device, you can still get the driver from a third party website.

Device Drivers

Drivers are files that control an external or internal device, such as a webcam. You can use a program like Driver Genius to find most common drivers for many devices. I don’t recommend it in this case because it is not a free program, and as the webcam itself retails for between $10 and $20, it probably isn’t worth it. However, if you have other driver needs, this is an excellent product for keeping your devices current.

The best free site to try is Driver Guide. They have an extensive list of drivers for Sabrent devices and your driver should be on that list when you search by model number.

Installing Drivers

Once you have found the correct driver, you need to install it. When you click on the download at the site, you will be asked if you want to run or download the driver. Choose download. The best and easiest way to do this is to download it directly on your desktop so that it is easy to find. Click on the desktop icon to the right of the download box to save it to the desktop. When it has finished downloading, find a blank space on your desktop and right click on it. Choose New and then Folder. Name it something that tells you what it is, like Drivers. Right click on the downloaded driver file to drag and drop it into this new folder.

Update Drivers

Once you have it downloaded, you need to update it. Go to Start and then Control Panel. Choose System and then Device Manager. Find the device that the driver is for and click on it. Choose Properties and then Driver tab. Click on Update Driver. You will then follow the directions to find the driver folder. The system will update the driver to the .INF file. Once it has finished, reboot your computer so that the driver will update.

This should allow you to run your webcam. If you are still having problems, you may want to look at getting another webcam. This model is no longer sold or supported by the company so it may be time for an upgrade.

I’m assuming you’ve checked all of the likely suspects for audio loss - mute buttons, speaker connections and power cables. If it is not any of these issues, it is likely a driver problem. Sometimes when you reinstall Windows XP, you need to reinstall your sound drivers in order for your audio to work again. This is more of a problem with high definition sound devices. If you are using high-def devices, you often can use this Microsoft Bus Driver to optimize performance.

Soundcard

One option is to manually find the soundcard and then download the driver that is made for it. You need to find the sound card manufacturer so that you can go to the website for the driver. If you don’t know the soundcard manufacturer, follow these steps:

1. Click on My Computer, then choose Properties.
2. Click on the Hardware tab.
3. Choose Device manager and expand it by clicking on it. This will tell you what type of soundcard you have.

Download Your Driver

Now that you know where your soundcard came from, go to that website. Most websites will have download buttons for the drivers that are easy to find. Most of the time, just push the download button and let the system run. You can either download it directly to the correct file, or download it to your desktop to install later. Most of the time, you can download a new driver without unistalling the old one. If, for some reason, you want to uninstall the old driver first, follow the numbered steps above, but when you find the driver, right click on it and choose Uninstall.

Driver Detective

If you don’t want to worry about locating and downloading your drivers manually, you can use a program like Driver Detective to do the work for you. This download will manage your drivers in Windows XP and Vista so that you can easily download the proper drivers for all of your devices.

Reinstalling your soundcard driver should solve your audio issues and have you back up and listening in no time. If you’re still having problems, please let us know.
