Add/Remove Hardware Sound Keeps Going Off and the Computer Freezes while it Happens

The Add/Remove Hardware sound keeps going off on one of my user's computers. He also says the Safely Remove Hardware icon shows up in the system tray suddenly. His computer completely freezes when this happens. The whole thing only lasts about 5 seconds.

It's random and I have not seen it happen. He only has his mouse and keyboard plugged into the computer. I moved them both to different USB ports. Same thing. I gave him a new mouse and a new keyboard. Same thing.

He's on a Dell Optiplex 740 with Windows XP. Does anyone know what causes this and how I can stop it? Please let me knowif more information is needed.

Thank you.

Worth updating all drivers and failing that:

Add in your system environment variables the variable
DEVMGR_SHOW_NONPRESENT_DEVICES
set it's value to: 1
reboot your machine
goto your device manager
show all hidden devices

Now you can see all devices you ever installed, you can proceed to uninstall any that are no longer valid.

Without this environment variable you will not see the devices that are no longer present.

Sounds to me like there is a short in the motherboard or the power supply. I would try a different power supply first..

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Did the problem start after installing MS update(s)?
If 'yes' you could try & locate the update(s) to uninstall, then if problem is resolved, re-install them individually.... or use System Restore to a time prior to the update(s).

Also worth checking for Malware infections by running Malwarebytes, and Hitman Pro 3, a 'Second Opinion Malware Scanner':

Hi,

Thanks for all of your help with this. I appreciate the quick responses!

After I posted this on Monday, I decided to try a 2nd new mouse and so far so good. If it starts up again, I will be trying the suggestions above.

The case can be closed.

Thanks!
