raman, aving your cpu at 100% is not good at all, that why comps crashes alot...you proccesor having to work to hard..get windows task manager up, click proceses and click the cpu tab a few times and see which one comes to the top with most cpu usage, if it says something idle proces or something ignore it, but anything else, type it into google and see what itis, if its something you dont need then end the proces.
