Windows 10: Consistent pattern of CPU usage in task manager in idle

Hello every one i am using windows 10 in DELL G3 gamming laptop , i am noticing a consistent pattern of CPU usage in task manager in idle, not sure what the reason is , my fans too are spinning at high speed due to this, please look in to it and tell whether there is any issues to be addressed.Device name ########Processor IntelR CoreTM i5-10300H CPU @ 2.50GHz 2.50 GHz Installed RAM 16.0 GB 15.8 GB usable System type 64-bit operating system, x64-based processor Edition Windows 10 Home Single Language Version 22H2 Installed on ‎14-‎04-‎2022 OS build 19045.3448 Experience Windows Feature

Task manager showing 100% CPU usage at idle.

Task manager is showing 100% CPU usage at idle. If you look into the details to see what if anything is really using that much processing power and it shows "system idle process" at 99-100% when at idle. This is normal I know but task manager should not
be including "system idle process" when its calculating CPU usage. This is causing my CPU to ramp up and my fans to stay at full speed at ALL times.

Things I've tried:

*Re installing windows. (multiple different ways and at different times throughout the diagnosing process)

*Removed all ram and just a single stick (multiple different known good sticks) & and two sticks

*Removed GPU

*Cleared cmos

*Bios Update

*Multiple different bios setting and power settings

*Adjusted all windows power settings plugged in and on battery (tho this is a pc)

I'm at a loss. There is no performance loss but having my CPU automatically overclock and fans at full speed all the time is not going to work.

Oh and on a weird side note, few nights ago was working on fixing this issue like usual and ended up accidently leaving the computer on all night (which I don't do because I don't like leaving the CPU overclocked it see's about 50-60c at idle) when I woke
up and went to turn computer off CPU usage was at 1-4%...!!!! I was shocked and thought that some how it must have updated widows and fixed the issue. But issue came back next re-boot.

SYSTEM SPECS:

Mother Board = z77a-gb65

CPU = i3 3240

RAM = 16g (4x4g 2 corsair 2 pny)

GPU = Gigabyte GTX 970 G1

Thank you to anyone that can help...

 

Task Manager High CPU Usage

I have the same problem myself with it only happens when I scroll through task manager and open and close it. I don't know this for sure but the reason this probably happens is that you may have a lot of processes running and task manager is using a lot
of the CPU to process the usage of each program.

What I have done is disable data that I don't need to see like network usage and GPU usage and it drops the CPU usage a bit. I have also enabled everything and scrolled up and down on it and task manager uses almost twice as much.

I would suggest disabling everything but CPU, disk, and RAM, (I would not suggest having GPU on because it is almost always at 99% unless you have FPS limits).

 

noticing high CPU usage in the task manager when it is idle...

Hello Microsoft. I have Windows 10 Pro 21H2 installed on hp ProBook 450 G4. I am noticing high CPU usage in the task manager when it is idle, or when i'm not doing CPU intensive task, like browsing, text editing, etc. When I change focus to task manager, everything cools down. When I minimize or change focus from task manager, even without minimizing it, I can see CPU rises upto 50% and task manager is consuming it. I have tried scanning the system with Defender, no luck. I updated my system BIOS to the latest. Still problem exists. Can you assist me to get rid of the situation?
