I've got an issue I haven't seen before . . . Task Manager is constantly pegged at 100%, and games have been crashing my display. On the other hand, the Core Temp app gives different numbers, and right now, while I'm typing, is showing 5%-7%. Task Manager is still pegged at 100%.
I have tried a couple of Windows 10 DeBloaters to no avail, and if I "end task" on a consumptive process, another process will jump up and become as consumptive!?

Reinstalled Windows
Did you try enabling all of the C states in the BIOS; C1E, C3, C6 and C7?

Not sure how running a Linux CD is going to solve anything. Whether Linux confirms that there is a problem or not makes no difference. When you are in Windows, there is obviously a problem. The BIOS is not enabling the C states correctly. The BIOS always needs to enable C1 so an idle CPU core does not have to constantly stay active in the C0 state.

Edit - I found the power plan setting that can cause this problem. Does this look familiar? The System Idle is showing that the CPU is idle 99% of the time but ThrottleStop shows the CPU spending 100% of its time in the C0 state.

I had this issue before. I found out it was malware that's causing it and reformated my whole PC. It was a test PC so I didn't have any important files on it.
