Windows 10: cpu uasage high until open task manager

My Acer laptop's fan has been running very loudly these past few weeks. When it gets too unbearable, I open Task Manager, only to find that my cpu usage lowers dramatically from 100% going as low.

High CPU usage until I open the task manager.

Hi mus890,

Open Task Manager (Ctrl + Shift + Esc)

If necessary, choose the Processes Tab

Click on the CPU column header, so that arrow faces down

Leave that window open to monitor your system

When this high CPU occurs, minimize whatever windows you are working on and check what are the top 5 processes listed at that time?

 

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).

 

High CPU usage when opening task manager

Hey, so as said in the title, my CPU usage is unusually high when I open task manager. After about a second, the CPU usage starts dropping down to around 5%. I've ran malwarebytes multiple times, but the issue still persists. I would like to avoid resetting
my PC if possible.
