Can anyone tell me why my CPU usage is so high? If I am doing one thing on my pc it slows it down to a crawl with CPU at around 100%. It has just been in to PC World for the annual healthcheck and they could not enlighten me. Please can anyone help me?
Are you looking at the correct value in Task Manager? It's not the the bottom number in list the CPU usage is on the bar at the bottom. The big number at bottom of list is CPU free, not used. A lot get mixed up with this. just click on a blank part and watch both figures how they change. On the Bar goes up, and Free goes down
