Windows 10: Found fix for my task manager showing 100% cpu when system was clearly at 1~9 in other...

Task manager would show 100% when others like afterburner and msi center showed the real value. changing boot cores in msconfig to 12 from auto fixed this and somehow increased my FPS, hope this helps anyone googling task manager 100% reddit. (select boot > advanced options to find it)

Task Manager showing 100% CPU usage

Task Manager showing 100% CPU usage. A few days after I built my PC, all of a sudden task manager started showing 100% CPU usage no matter what programs are running and it was also showing very high power usage. I ended up temporarily fixing the issue after I did a full fresh install of Windows, 2 months later and now the 100% CPU issue has returned. I checked sensor connections and updated my bios with no luck. I have NO performance issues, I used the Intel Extreme Tuning Utility and it showed no high CPU usage. CPU and motherboard specs are below:

Windows 10 Home 64-bit

Motherboard: Z690 UD DDR4

BIOS: F7a

Processor: 12th Gen Intel(R) Core(TM) i9-12900K (24 CPUs), ~3.2GHz

Has anyone else run into this issue? Does anyone know of possible solutions?

 

System not slow at all but task manager shows 100% CPU at ALL times

My Task Manager application (Windows 10 22H2) shows 100% cpu usage at all times, but the system is not slow.

Using Process Explorer, it shows that my idle process is in fact 95%, and the other processes run at the same rate towards the actually used CPU time.
My task manager seems to be miscalculating, by only counting the percentages of the time it's in use:

- it shows that 100% of the in use time is in use.

- low using applications shows high CPU usage rates that correspond to their relative rates to each other.
Is there a way to fix the miscalculation my Task manager seems to be doing?

 

CPU @ 100% in Task Manager.. but in error


Sailindawg, did Resource Monitor show some silly high % use, in the millions/billions? Does the 'Details' tab in Task Manager show 'System Idle Process' normal? It does sound like you have the same issue, I've still not fixed it. You might be lucky and a BIOS update works for you as it has others, I'm stuck on the B2 stepping which means I can't upgrade the BIOS *Sad

MrPumpkin, what process does task manager say is using the most CPU usage?
