Question Pc randomly started stuttering and major fps drops

[Ephremwwww]

As the title states randomly this week my games have started to stutter and have major fps drops every few seconds (Modern warfare the only one unaffected). I have re installed drivers gone back to old ones and made sure every driver was updated multiple times. I am not sure why this just randomly started happening but I've been trying to fix it for 6 hours with no results. I've gone through so many threads and nothing has worked. I have also looked at temps and everything to double check but notice nothing.
