Hi melissa-m,
Try the below troubleshooting steps:
Step 1: ****Put the computer in a clean boot state and check if the issue persists.
a. Putting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue.
b. Refer the following Microsoft KB article for more information on how to troubleshoot a problem by performing a clean boot in XP:

Note: After troubleshooting, make sure to put the computer to start as usual as mentioned under the section 'Steps to configure Windows to use a Normal startup state' in the above KB article.
**Step 2:**Also check if there any software available for the Gaming Mouse.
**Step 3:**You may also install the latest drivers for your sound card and then check for the issue.
