Itose

Hello.

I have owned this system for little under a year now and have been experiaing this problem for a while, it seems to go away and then reappear every so often.

My CPU (Quad Core @ 2.4Ghz) will spike from 36% - 100% whenever I open something or load a webpage, if playing music whilst this happens the music lags and so does the mouse for a few seconds. Perfect example below;

Heres the processes running at this time -


Anouther thing wrong with this processes thing is I DO NOT have steam open, I closed it this also seems to happen with Firefox and Utorrent, I clsoe them, processes still logs them, I attempt to end task and it doesnt allow me to.
