How to fix Logitech webcam, sound, scanner issue in XP?

Hi experts there,

Hi experts there,
If you think the problem started after installing the driver for the Logitech webcam, uninstall and reinstall the affected devices. Download the free version of Revo Uninstaller and install it. Once installed, start Revo Uninstaller then select your sound card software among the applications and click “Uninstall”. Follow the normal uninstall process. When you are prompted to restart the computer, click to restart later.
When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer. When it is finished, close Revo Uninstaller then restart the computer. After booting, repeat the same steps to uninstall the scanner and webcam software.
Once everything is removed, install the sound card back then see if the sound of your computer is restored. Install the remaining devices one at a time.
