Cpu showing 100% in task manager. Games crashing

I have a AMD 7 2700x in a msi x570 carbon wifi mobo and for some reason lately the cpu has been showing 100% usage in task manager. I have tried a couple different a/v softwares, driver update programs, roll backs to no avail. I was planning on doing a full format and reinstall but figured would give this a chance first as I have a ton of software that I don't really feel like reinstalling over the next couple days.
