Microsoft Help and Support says that "Code 28 (The drivers for this device are not installed)" appears when the Windows Sound System Compatible Driver for the Windows 2000 operating system is deleted upon the upgrade to Windows XP. It's possible to repair this code.

Click on "Start." On the "Start" menu, click on "Control Panel." In the "Control Panel" folder, click on "Performance and Maintenance." Click on the "System" folder in the "Performance and Maintenance" folder. Click on the tab titled "Hardware." Click on the box that says "Device Manager." Click on "Sound, Video, and Game Controllers." Right-click on the device that prompts Windows XP to display Code 28 (it should be Windows Sound System Compatible Driver, also called the WDM driver). A drop-down menu will appear. Click on "Update" and an Update Wizard will guide you through the installation of a new device driver, which should stop Code 28 from appearing on Windows XP.

error code 28, means a Driver Error,

the solution is to go to the device manager,

1.) start, control panel, system, hardware, device manager,
2.) locate a device with a yellow highlight
3.) right click it and select update , follow the onscreen instructions

or
reinstall the driver using the driver cd. that came with it.

if that fails you need to go to the manufactures website for that particular device , locate the driver and download it, then install it. PS if its on the mainboard you can go to the OEM system builder you have like dell or hp , if you dont have and oem system go to the mainboad manufactures web site, Biostar and MSI.

Do your Wireless Device (PCI or USB unit) comes with an installation CD? If so, use the CD to install the software/drivers.(Instead of using the Windows wizard). Remove any previous installation before reinstalling with the CD.

Resit your device to a different USB port or PCI slot. If the drivers/software are properly installed, windows will detect and installed the device correctly.

Cause of the Code 28 Error (In general)
A Code 28 error is caused by a missing driver for that particular piece of hardware. There are several of reasons that a driver might not be installed for a device but your troubleshooting of the problem will be the same no matter the root cause.

Resolution
1.Restart your computer if you haven't done so already.

There is always the slim chance that the Code 28 error you're seeing in Device Manager was caused by a fluke with Device Manager or in your BIOS. If that's the case, a reboot might fix the Code 28.

2.Did you install a device or make a change in Device Manager just before you noticed the Code 28? If so, it's very possible that the change you made caused the Code 28 error.

Undo the change, restart your PC, and then check again for the Code 28 error.

Depending on the changes you made, some solutions might include:
•Remove or reconfigure the newly installed device.
•Roll back the driver to the version prior to your update.
•Use System Restore to undo recent Device Manager changes.

3.Update the drivers for the device. Installing the latest manufacturer supplied drivers for a device with the Code 28 error is the most likely solution to the problem.

Important: Make sure you install the drivers for the correct operating system. Example, if you're using Windows 7 32-bit, install the drivers designed for that specific version of Windows. Most Code 28 errors are caused by updating or install the wrong drivers for a device.

4.Update your OS to latest Windows service pack. Microsoft regularly releases service packs and other patches for their operating systems, one of which may contain a fix for the cause of the Code 28 error.

**Note: Certain service packs for Windows Vista and Windows 2000 have contained specific fixes for some instances of the Code 28 error in Device Manager.

5.Replace the hardware. As a last resort, you may need to replace the hardware that has the Code 28 error.

It's also possible that the device is not compatible with this version of Windows. You can check the Windows HCL to be sure.

Note: If you still think there is still a software/operating system component to this Code 28 error, you could try a repair install of Windows. If that doesn't work, try a clean install of Windows. Not recommend doing either of those more drastic options before you try replacing the hardware, but you may have to if you're out of other options.

Hope it helps.

How to Fix a Code 10 Error
A Code 10 error usually occurs due to:

• Missing device driver
• Malfunctioning device driver
• Incomplete device driver files

If the device due to which the error has occurred contains the valueFailReasonString in its hardware key, then this string is displayed as an error message. Otherwise, the device displays the following error message:
This device is either not present, not working properly, or does not have all the drivers installed. (Code 10)
Most of the time, you can resolve this error by updating the device driver for the faulty device. To update the driver, select the Systemoption from the Control Panel. In the System Properties dialog box, select the Hardware tab, and then select the Device Managerbutton. Scroll through the Device Manager window and identify the faulty hardware device. Right-click on this device and then select theUpdate Driver command. Next, follow the screen instructions to update the driver of the selected device.
Causes of System Errors
System Errors Usually Occur due to:

Steps to Prevent System Errors
With a little vigilance and extra precaution you can easily prevent most system errors. Some of the tasks that you can perform to prevent system errors are listed below:

• Keep your operating system, device drivers, and software applications updated with the latest hot fixes, security releases, and updates.
• Run regular antivirus and anti spyware scans to keep your PC free from harmful and disastrous malware. Always keep these software updated with the latest security releases so that your system is always protected against malware infections.
• Avoid opening attachments of unsolicited emails and visiting dubious websites.
• Do not download freeware and shareware from websites whose authenticity you aren’t sure of.
• Be very careful while downloading ActiveX controls from various websites. ActiveX controls provide their master with complete control over your system and therefore, a malicious ActiveX control can cause severe damage to your system and may also enable a hacker to steal your personal information.
• Last but not least, perform regular registry maintenance to ensure that your registry is free from errors. 90% of all system errors are connected to the system registry in one way or another. You can easily perform registry maintenance with the help of a registry cleaner such as Ccleaner/Regine. These softwares will provide you with a simple-to-use graphical interface and enable you to scan and clean registry errors in just a few mouse clicks.

It is a very good idea if you run a registry cleaner using Ccleaner/Tuneup/Regine etc...

I'm unable to connect my western digital hard drive to my Windows XP computer via the USB port. When I check the USB 2.0 Controller in the Device Manager, there is a yellow exclamation mark (!) next to it. When I check on the status of the USB 2.0 Controller, the following message appears:

The drivers for this device are not installed (code 28).

What do I do now?
