Windows 10: I completely reset my pc, and my MSI Center and Task Manager are both stuck at 100% CPU. I...

I believe to think I have a virus on my computer however antivirus says I'm all clean. What do I do. My CPU usage is at 100%. Windows Security won't open even after resetting my pc.

CPU constantly at 100% in task manager

Sorry for the late reply to this. I have tried switching the plan to power saver and i set the cpu to 80% but task manager just has it stuck at a lower % with a constant amount. But process hacker displays hardly any %. I also tried clean boot, even with nothing loaded in startup options it still is stuck at 100%. I even went and reset the PC but still task manager remains at 100% cpu constantly.

 

Task Manager incorrectly claims 100% CPU usage

Whenever I open task manager, It will constantly say that my CPU usage is at 100% and doesn't seem to dip below 99%, even when otherwise idle. However, my PC is not having any performance issues I would expect with an overloaded CPU. I can run games and benchmarks without issues and results appear to be perfectly normal. Performance monitor, MSI Afterburner and GeForce Experience overlay all suggest my idle CPU usage rarely peaks above 5%. I can only assume there is a bug in Task Manager.

I am running win 10 home on a custom PC with an MSI z490 Gaming Plus motherboard, i7-10700F 2.9GHz 8-core 16 thread CPU, Corsair DDR4-3200 8gb x2, MSI RTX 3060, Crucial P2 M.2 NVME SSDs (2.5tb total)

What could be causing this and how can I correct this?

 

CPU constantly at 100% in task manager

That is exactly what I did previously. I tried setting max to 80% to test and task managers cpu displays constant 80% instead of 100% on the performance tab and 80% above the cpu column in the users tab. Sadly it has no effect but thank you for the suggestion.
