Man alrite i tried the first steps posted here didnt work for me
reason being is i don have a winupdate anywhere
and i dont have any other file that runs close to even 20%
so i have no 'suspects' usually wen i click task manager
i have system idle running high on its 90's and iTunes or firefox
competing for 02%... and nothing else...

I got the same symptoms but not the right cure...
any help?
