CPU Usage 100% until Task Manager is opened

Hi,

I have a i9-9900k 32gb Windows Pro 21H2 19044.1586 desktop that randomly starts freezing up. As soon as I hit task manager, I can see the CPU is 100% for a second after opening, after which it goes down to normal levels and I can use my PC normally.

I have searched for answers and found thread Redirecting but that's from 2015 and it's now closed. I have tried the solution listed there and on the last step I'm getting access conflicts due to files being in use. What else can I try? Or if that solution is still valid, what can I do about the files that can't be accessed due to being in use?

Thank you

 

CPU and GPU usage at 100% until task manager is opened

Recently, I have been seeing that my CPU temperature is extremely high (80C) during idle or browsing internet and this changes when I open task manager to check what is using my CPU so much. As soon as i open task manager, my cpu usage goes down from 100% to 6-10%.

I am familiar with the bug from windows that causes the CPU usage to be at 100% when you open task manager for a split second before it can read the temperature and that's why i use msi afterburner to read my CPU and GPU usage as well as temperature.

During idle, when my laptop is plugged in and left unattended without task manager open, but with msi afterburner open, my CPU temps go crazy while my CPU usage gets rocketed at 100%. This also happens with the GPU sometimes.

I have read online about this and someone said it could be a virus that uses crypto mining software to hijack my hardware. This is a big issue as when i am doing my work it constantly causes interruptions if i dont have task manager open.

I need help to fix this and how to prevent this from happening in the first place I have run multiple virus and antimalware checks which have not changed anything yet.

thanks in advance to anyone that replies.

 

100% CPU usage in task manager after upgrading to W10

Thank you Krishna for quick response however it is neither of those reasons. I think it is a bug, it only shows 100% cpu usage but everything works ok . Never had this issue before only started after i updated from windows 7 to 10. The procantage usage
of cpu on some applications jumps from 5 to 70% in example : the task manager was "using" 80% of cpu and that just can't be right. Having said that i think the task manager's cpu usage shows wrong data (its bugged) somehow.
