Windows 10: Can you help resolve the intermittent lag on my PC?

I am having major lagging issues with my PC. The issue only occurs when I am playing video games. I get small lag spikes that last for about 2-3 seconds. It happens about every minute or so. I tested my Internet speed and have very good results. I have reset both my modem and router and that is not the issue either. I need desperate help to troubleshoot my PC to find the underlying issue. PLEASE HELP!!

Intermittent UI lag - Windows 10 21H1

Problematic files are photos and videos at this point in time. I use VLC for videos, and Windows Photo Viewer for images.
I launch all these directly and manually from File Explorer only - I don't use any third party media organizers.

Interestingly enough, mngerholds suggestion of using Procmon has unveiled that when lag does happen, there is a large influx of UDP and NetBIOS entries via SVCHOST -- but I'm yet to narrow down what the trigger condition is...

When there is no lag, UDP and NetBios entries are not present.

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.

• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.
