I occasionally get stuttering on my little old notepad PC. It's about a decade old, though does have in SSD.

The first thing I usually do it turn off WiFi ... it can sometimes perturb things.
I second looking at task manager ... when I get my stuttering, I almost always find some Microsoft background task using quite a bit of resource ... anti-malware; update checker; auto-defrag; and so on.
