Windows 10: System process very high power usage - FIXED

After days of searching the web and trying every possible thing from configuration changes to cleaning heatsinks, I finally found a solution: My pc is a Dell XPS 8930 with a GeForce GTX 1660 Ti graphics card. I went to the Nvidia website and downloaded and installed the latest game ready driver and GeForce drivers. Once this was done, the System process CPU usage went from 20% to 0%. And power usage went from Very high power usage to Very low. Praise The Lord!!!!I sincerely hope this helps someone else who has wrestled with this issue for days, weeks, or months.

system process high cpu usage

Hello,

To fix high CPU usage issue, please refer these steps:

Try to identify the process creating this issue.

Download Process Explorer from Microsoft:

Process Explorer - Sysinternals

Run the tool then select the system process, right-click and select Properties.

Switch to the Threads tab. This will show which file is using the excessive CPU usage, from which you can then attempt to diagnose it.

System and compressed memory high disk usage during file copy

Thank you Amarjeet_Paul.

I spent many more hours than I had hoped this past week reading and trying others' suggestions from this community on how to reduce high RAM usage due to ntoskrnl.exe. The "System and compressed memory" process remained the top consumer of RAM, using 500-900MB,
among all other processes running. I deemed it to be the likely culprit in making my computer use frustratingly sluggish. After completing your
third step, steps 1. & 2. provided no improvement in my case, the "System and compressed memory" process RAM usage has plummeted from the top of the Task Manager Process list to the bottom, running at a remarkable 0.1MB! That's a whole lot less than
1% of the targeted process' gluttony. You're hired! Ps. I'll be keeping an eye on the process' use as I get back to normal operations, and be back if it floats to high in the list. Or if the registry fix you suggested has compromised use in any way. Please
explain in simple terms what the insertion of your registry modification is doing.

Thanks again.

High system process CPU usage on connecting to the internet.

Hi, DivyanshJoshi,

Thank you for letting me know that you've already tried the steps I suggested, including a clean boot, and are still experiencing high CPU usage from the System process when connecting to the internet.

In that case, it might be helpful to try some additional troubleshooting steps, such as performing a system file check (SFC) scan or checking for problematic drivers or hardware components. Updating your BIOS firmware to the latest version might also be useful.

Please let me know if you have any other questions or concerns.
