Weird choppy playback issue

Hi, so I've been dealing with this weird playback issue on Premiere Pro all day today. The issue starts happening after an hour or so of editing. I've cleared my media cache, and checked if my software is up to date alongside my PC drivers.  The only way to temporarily stop this issue is by restarting my PC.
