Sounds like some program updated and you didn't know it updated and not its more a resource hog. You got 2 options. Uninstall things see if it gets better or reformat (because that will get rid of things too)... It sounds like you're not considering the former so I would suggest the latter. Because if you haven't changed anything your doing then it shouldn't give results your not expecting. Simple as that, Einstine would say expecting a different result would be the definition of insanity. And we can't convince you to uninstall things that hay perhaps have updated behind your back and without your knowing.
