High CPU Load - System Idle Process


I have an issue with a Server 2011 machine.

It has 24GB of ram and a xeon processor. The issue is that the CPU is continually high - when I look it seems to be system idle process that's using the majority of the CPU load - any thoughts on this? I have upgraded the ram from 16GB to 24 today and it hasn't made much of a difference.

Which is good.  That means the CPU isn't doing anything and is waiting for work.  Cough - it is idling.  Ideally when it is just sitting there the System Idle Process should be around 99%.

Give it some work or put a load on it and that System Idle Process will drop.

System Idle Process means the capacity of CPU that is idle or not being used and is available for usage.  Upgrading memory will not resolve CPU usage but may alleviate high disk usage caused by swapping.  Below is a screen of a system with 99% system idle process which means only 1% of the CPU is used.

If the CPU Usage is low as shown in the screenshot above, prior posts are correct.
But if you have a high load, but cannot see why (i.e. "Idle" is high), it is probably a hardware issue.
