CPU Usage is fluctuating

My CPU usage is fluctuating even though I am not doing anything on my computer, it keeps on going from 3% to 18% constantly. The main thing that bugs me about this is, my Fan will start blowing really loud and then go quiet every 15 seconds when the CPU usage goes up. Any Ideas on what I can do to stop it? (I have a image from the task manager, but I dont know how to insert in this)

Windows does that.

There are hundred reasons such as Windows is checking for updates, rearranging memory, the scheduled events are checked, it goes on and on.

The only way to stop this appears to change the OS or turn the machine off.

and I would find out which Process is using up this CPU Usage time. I always click, (or click twice), the CPU column header to re-order the processes in cpu usage order and that allows me to watch the list more easily.

I also make sure that the Task Manager "Shows processes for al users".

My first guess would be "Indexing" which, if enabled, will catalog files on a new system during system idle times, (idle as in, I am not doing anything on the system myself at the time. A computer is never really idle). But that's just a guess as all systems are different.
