Question loss of cpu usage during gaming

[goingincircles]

hi guys im after some help?
basically i seem to have lost cpu usage and fps in games! which started happening about 4 days ago. i play f1 22 and cod warzone and get good fps but now its seemed to drop and ive noticed my cpu usage is staying below 10%.
il add some pics and system at end. i built this system myself around 3 months ago and have had no problems at all!!
ive literally started again with fresh install of windows and graphics drivers (straight from nvidia) but no change :-(

this issue started out of the blue! i played warzone at night the cpu usage was low 40`s as normal and when i turned on next day it started happening low fps and cpu usage dropped massive

please let me know if you want me to add any info/pics

How old is the PSU in your build?

ive literally started again with fresh install of windows
Where did you source the installer for your OS?

No windows updates in between?

What might have changed in the past 4 days?

I might suspect a cooling issue.
Your aio runs via software; possibly that is messed up.
Run hwmonitor,
Look at the idle temperature.
It should be some 10-15c. over ambient.
After gaming, look at the max temperature.If you see a few cores at 100c. in red, it means that you have throttled.

the cooling looks ok ... thtas after an hour on f1 22

on core usage it says 76% but that only happended during a load up screen

Sims are often single threaded.
76%cpu busy may reflect a single thread at 100% and a few support threads.
As another test, run the cpu-Z bench and look at the single thread performance rating.
A 12400 should be about 700:

it seems to be more when gaming? i can run cinebench and all cores will max out just not when a game is on???
