Processador e RAM com consumo alto!

De uma hora pra outra meu processador e minha memoria ram ficaram com consumo elevado,pesquisei muito e verifiquei os processos e nada.Segue abaixo o log.
Obs:quando eu uso a rede(ex:ver video,ou acessar alguma pagina)o processador aumenta chegando ate mesmo nos 100%.
