you may need to reinstall sound driver.

If you are trying to use the drive in a windows XP system you will need a driver due to the fact its a SATA drive (very few are supported by Win XP) .
You should be able to find a Windows XP driver on the Western Digital website.
At the start of the Windows XP install process you will be asked to press F6 to load SATA drivers.
If my memory serves me right you will need to have the driver on a floppy disk to install them.
This should sort your problem.

go to HP.com and download the sound drivers
install and restart the comp

ok delete all the adapters in device manager and then uninstall your wireless adapter(after turning off the computer) turn the computer back on with adapter still uninstalled shut down the computer again and reinstall your wireless adapter start computer and it should find the wireless then if need be install drivers again

Did you reinstall the drivers for the device? Check the Device Manager for your system and see if Windows sees the wireless device. If you have a red X, the device is disabled; if you have either an unknown device or the wireless device with a yellow dot with a black exclamation point, then either the driver is not installed, or the driver is improperly installed.

Common problem. CD driver did not install correctly.

Go to Device Manager. Unistall the CD drive. Reboot.

The Operating System will then rescan, locate the drive, and reinstall the driver.

Good luck.

Reboot and keep tapping on F8 to go to Safe Mode. Do not put the reinstallation disk yet. Once in Safe Mode select "last known good configuration".

You can also run "Chkdsk" from the C hard drive Properties if you get to Safe Mode. Double click "My Computer", right click on C drive, select Properties, select Tools tab, go to Error checking and click on "Check now" then check "automatically fix file system errors" and "scan for and attemp recovery for bad sectors" and click "start"

If that doesn't work proceed to do System Restore in Safe Mode or remove previous programs that may have caused your Windows to freeze. If you suspect virus, run your anti-virus in Safe Mode.

If none of the above works then try your XP CD (or reinstallation disk) and do a repair.

Solution
These errors are usually caused by a failed scan, a bad installation, communication problems or software conflicts. Follow the steps below until the problem is corrected.
Step one: Restart the computer
Close all programs and restart the computer. A required task might have stopped running or the system resources might have decreased due to tasks left running. Restarting the computer will refresh all Windows tasks as well as increase the available system resources.
Step two: Check for the correct entries in the Device Manager
Verify that the unit was installed on a DOT4 virtual port in the Device Manager.

1. Right-click My Computer , and then click Properties .
2. Click the Device Manager tab. (In Windows 2000 and XP, click the Hardware tab , and then click Device Manager .)

Check the list of installed devices for references to DOT4. If there are no DOT4 references, the software has not installed correctly.
If any of these entries are missing, the software did not install properly. Review the information in the HP document Troubleshooting Installation Issues for USB-Connected HP All-in-One Products in Microsoft(R) Windows (bpu01858) for installation assistance.
Step three: Check for communication problems between the all-in-one and the computer
Communication might have failed between the all-in-one and the computer. Review the information in the HP document USB Connected HP All-in-One's Software Reports a Disconnected or an Error Status (bpu01859) to check for communications problems between the HP all-in-one and the computer.
Step four: Check the computer to see if it is infected with a computer virus
If the all-in-one prints but will not scan correctly and does not show any symptoms of communications problems, the computer might be infected with a virus. Some viruses try to disable virus scanning software and in doing so disable scanning from the all-in-one. The following are symptoms a virus problem:

• The scanning software works after installing the all-in-one software until the first time the computer is restarted.
• In the Device Manager, opening the Properties of the Imaging Device entry will reveal a status of "code 19" or "code 28".
• A Scanner Cannot be initialized error occurs. While this error may other reasons, a virus will cause this error.

When the all-in-one is turned on and connected, follow the steps below to see if this is the problem:

1. Right-click My Computer (click Start first in Windows XP) and then click Properties .
2. Open the Device Manager:
   • Windows 98 and Me: Select the Device Manager tab.
   • Windows 2000 and XP: Select the Hardware tab, and then click Device Manager .
3. Locate the Imaging Device entry and click the plus (+) beside it. It may have an exclamation mark beside it.
4. Right-click the all-in-one entry under Imaging Devices, and then click Properties .
5. A Properties screen will open. Look at the Device status section.
   • If the Device status reads, “This device is working properly”, the computer probably does not have a virus problem. Continue to the next step.
   • If the Device status reads “code 19” or “code 28” error, there is a good chance that there is a virus on the computer. Follow the directions in HP document Resolving the Error Message 'Class Installer Has Denied the Request to Install or Update the Driver' (bpu00740) to remove the virus and resolve the problem.

Hope it may helps;.
