That observation regarding the System process in Task Manager sounds pretty good to me.
Expand your TM window a bit and you can click the column headers (like CPU) to sort and see who is consuming the most. You want System Idle Process to be at the top for CPU when you are not doing "anything". 80s and 90s are generally good. If something else is taking too much CPU, then you see who it is and decide what to do about it.
You can sort my the Mem Usage column to see where your memory is going, etc. The columns display will get updated and bounce around.
I like to click View, Select Columns and add the VM Size column to see what is happening to Virtual Memory. Expand TM wider to see the columns if needed. Spybot's resident TeaTimer is a VM hog if you ever use it!
Some things you may have installed (such as real time monitoring softwares) will take up a lot of CPU and memory, so they may need to be reconfigured, uninstalled, etc.
What kind of anti virus/malware software do you have installed?
You can download the free Process Explorer from www.sysinternals.com to drill down under each process to see more about what is going on. PE is like a magnifying glass that lets you see every process and under every process and terminate suspicious things to see if your system behaves better. It won't fix it, but you will know what it is and then you can fix what needs fixing.
Can you better define what noisy and working hard means?
