Puzzling situation with 9700k

[staaan]

Can anyone help me figure this out?

 

Got a 9700K that was overclocked now getting this constant 100% showing in the task manager only. 

 

The CPU is water cooled with a full custom EK loop (1xPE360 + 1xPE240 rads) (not on the GPU yet but will be eventually so it is overkill, for now)

 

I did have it overclocked to 5.1GHz for about 8 months and everything was good. Idle sat around 30c and maxed out at 59c with CPUz. (haven't lapped or de-lidded)

 

Have since done a windows reinstall and bios m-flash but alas, no luck. 

 

 

CPU idle

 

CPU stress

Just restart Windows Explorer. When you click on to it in Task Manager the kill button will turn into restart.

What's puzzling is why Intel nerfed the i7 lineup and made one without hyperthreading

No, unfortunately

yeah this model sits in a very weird place for intel, but she does perform in gaming

This is kind of a shot in the dark, but uninstall the NZXT software. I had a similar issue with my 7700k where it would load to 100% at idle. The issue did not persist after I reset my machine though.

Seems like in the first image, there's a lot of procesesngoing on doing stuff.

 

Kind of odd for even stuff like snipping tool to be taking up so many resources.

 

What happens to usage if you end those specific tasks

 

Edit: I think task manager is just reporting bad information.

 

You've got two different monitoring software corroborating low CPU usage and it's just taskman that's being a bitch.

 

I'd chalk it up to taskman being stupid.

 

Quick Google shows many hits on "incorrect task manager CPU usage" revolving around content updates and most remedies are just "ignore it"

tried to reset Windows with keeping files?

No wiped both drives on there. the 3rd is the bootable usb

No luck here either

I agree it's gotta be task man, hwmonitor should otherwise pick it up. 

 

Could there be an issue on the board giving the CPU incorrect voltages?

 

My only other guess would be a hardware problem, might just need a re-seating on the cpu.
