If your CPU remains heavily loaded without your browser open, then this is not what is happening. Have you checked your Task Manager to see what is consuming the CPU's processing power? Do you have an active and up-to-date virus scanner?

Just after opening Task Manager Cpu going to normal usage. Something is detecting Task manager and going to stop itself. Yes I have active and up to date Antivirus.

I hope Dutch's comment was helpful for you, as I'm not very technical person and can't answer this..
