[SOLVED] CPU Usage is always at 100% ?

[Tobyhacking]

My CPU seems to recently running at a solid 100% in Task Manager even when nothing is running. All other statics look fine - memory running at 20%. Its not against any specific process the CPU loading it just seems to be the latest used. My specification is as follows:

- Intel Core i7-13700K
- MSI PRO Z790-A MAX WIFI
- Microsoft Windows 11 Home (x64) Build 26100.3775 (24H2)

I've tried the following:
- installed latest BIOS
- checked windows updates
- checked drivers
- disabled all start up programmes
- run two different virus checkers for malware
- checked system files with sfc /scannow command
- defragged HD and run chk dsk
- tried switching off print spooling
- switched powerplan to balanced
- switched off tips and suggested ways in notifications
- cleaned fans


HWInfo shows total CPU usage as 100% and average core temperature as 66degrees when idle with no thermal throttling.

At a complete loss what to do next, any help appreciated?

So its finally solved, seems to be something to do with power management. I found a thread that said enter the following into Cmd

PowerCfg /SETACVALUEINDEX SCHEME_CURRENT SUB_PROCESSOR IDLEDISABLE 000
PowerCfg /SETACTIVE SCHEME_CURRENT

CPU load and temperatures returned to normal and Cinebench test showing normal. Thanks for all your support.
