Everything looks OK. The System Idle Process is what Windows does when there is nothing else to run
- I understand what you're saying but I don't think you understand the issue.
The best way I can describe it is like a car idling at max RPM (100% CPU usage + high temps). When I take it to the mechanic (ie Task Manager or Process Explorer) the issues are not apparent (ie CPU usage drops to near 0% and temps drop to 30C). When I leave the auto shop, the revs max out again, instantly shooting up temps and slowing down the machine.
ATM, I've left Task Manager open to stabilize the system. This is the only way I can keep usage and temps stable.
