Sorry to hear that you're having trouble. What you're describing is known to happen when previewing your project while it's on the timeline, but shouldn't ever happen in a produced clip.
Although you've provided some info on your system (and a lot about your CPU), not much of that is actually helpful in understanding what's happening. Producing issues like you're seeing aren't related to how fast or slow your CPU is, although speed certainly plays a role in how
long the producing takes.
To help us help you, there is a detailed guide for running the Windows DxDiag test in the
Read Me Before Posting section at the top of the PD forum, Following those steps to run the test and attach the results - along with posting the exact version of PD16 you have running - will give us the crucial details of how your system is actually configured.
It would also be great if you could share a short sample clip from any of your sources that gave you problems in the produced video. You can upload it/them to a cloud folder and paste the link here. That way other people can see if there might be anything unusual with it/them.
It would also help to see what the produced issues look like, and you could upload the video to YouTube and share the link, or add it to the cloud folder.
If there's any content you don't want to share, you can try making a quick video of anything, like your kitchen or a TV show. For your issue, it's critical that there is a clear relationship between the audio and video, so keep that in mind. Then see if you can produce a short project that shows the same issues and share that here.
