Question CPU 100% Utilize

[riobijoy]

I am writing to seek assistance with a persistent issue I have been experiencing with my computer's CPU utilization. The problem is as follows:

My system's CPU usage spikes to 100% according to the Task Manager. However, as soon as I open the Task Manager to investigate, the CPU usage immediately drops back to normal levels. Once I close the Task Manager, the CPU utilization again surges to 100%, and I can hear the system fan spinning very fast and get Hot.

This issue is affecting the performance of my system significantly, and I have been unable to pinpoint the exact cause. Below are the specifications of my system:

• Processor: Intel i5 13600k
• RAM: 32 GB DDR5
• GPU: Zotac RTX 2060
• PSU: Cooler Master 650W
• OS-Win 10 22H2 Build 19045.4529

I have tried basic troubleshooting steps such as updating drivers, checking for malware However, the problem persists.

I would greatly appreciate any guidance or support you can provide to resolve this issue. Please let me know if you need any additional information or logs from my system.

Try using Process Explorer. This program is similar to the Task Manager but way more in-depth. It sounds like you have something running in the background on your computer that immediately stops as soon as it detects that the Task Manager is open.

It could be virus or malware related but it is usually something innocent like Microsoft doing some sort of update or running its memory checking utility in the background. I turn junk like that off to prevent these problems.

This sort of behavior is typically from a cryptocurrency miner. So yeah, use Process Explorer to find it. And if you still get this behavior, try renaming the executable.

look at the currents of your power supply.I don't know how long you have it and what exactly it is but I know that the graphics card you have and the processor suck it

I have run Process explorer and seen that nothing like that but as soon as it close the process explorer also cpu utilize high and get hot and if i open again task manager or process explorer fan speed decrese and cpu utilize back to 2 or 3 percent

How are you seeing 100% if you don't have task manager open?

When i open task manager,it shows for 2 to 3 seconds then get back to low

Try running core temp. It shows cpu utilization too.

Task Manager launching usually increases cpu utilization. This is normal.

If it only happens on this (and I just realized your OP says spikes of 100%), then this is normal. Task Manager has a lot of things it needs to do to present the information to you. After that, it's just gathering statistics once a second.

But the thing is when i close task manager the fan spin in full speed and temp goes up like anything,and then again if i open task manager cpu temp goes down as well as utilisation.

 

[hotaru.hino]

But the thing is when i close task manager the fan spin in full speed and temp goes up like anything,and then again if i open task manager cpu temp goes down as well as utilisation.

So what's the behavior here?

• CPU appears to be at 100% all the time until Task Manager or Process Explorer is open, then goes down, but ramps back up again once they're closed and stays that way
• CPU spikes up to 100% when opening Task Manager, then goes back down, then spikes up again after it's closed but will go back down

What you've been describing isn't very clear.

Did you try running CoreTemp? It allows monitoring cpu usage without opening Task Manager.
Or are you monitoring cpu usage with some other software?

Core Temp

Core Temp is a compact, no fuss, small footprint, yet powerful program to monitor processor temperature and other vital information.

www.alcpu.com

Do you have 100% cpu usage shown with Core temp running and Task Manager closed?

I will clear you,when my cpu utilisation is 100 and fan spinning fully in that time if i open task manager or process explorer cpu utilisation drops after 1 to 2 second and back to normal but then when i close the task manager cpu utilisation throttle up again and fan spins fast and temp goes up

That doesn't answer if it stays this way or if it goes away after some time.

Rename the Process Explorer executable to something else and run it again and see if the CPU utilization drops.

To be honest i don't know the files or process for renaming

 

[hotaru.hino]

To be honest i don't know the files or process for renaming

Go to where it's installed and select "procexp64.exe", then either:

• Left click on it once and wait a few moments
• Press F2
• Right click on it, go to "Show more options" if you're on Windows 11, then select "Rename"

I have an mini pc with an Intel N100 win11, during an update, task-manger was at 100% for minutes on end, while the Intel Arc software data overlay showed cpu usage at around 45%, Intel help said this is due to the different way the data is polled, but the cpu load was consistent for a long period of time, not some spikes, Ahhha, It does my head in, Anyway the guy who wrote the task manger for Microsoft has an Youtube channel out of interest.

How are you monitoring cpu usage with Task Manager and Process Explorer closed?

 

[Zerk2012]

You can just use MSI afterburner and have it show the overlay on your screen. Or download OCCT and check it in that program.

 

[PiersPlowman]

Could it be malware that recognises when process explorer is open, and then throttles down...?

Have you tried OCCT like I suggested it would be harder to make it notice all monitoring programs since a bunch of them exist.

EDIT Heck I have a Logitech keyboard G510s and it shows my CPU and Ram usage on a display on my keyboard.

I can hear the fan spinning very fast and rear fan outake warm air,and in speedfan temp shows 95 degree

That doesn't mean anything about cpu usage. Probably your cpu cooler is failing.
Use software that can show cpu usage. CoreTemp for example.

What cpu cooler are you using?
