Windows 10: System uses up to 100% CPU

After some time of using my pc some of the internal Windows systems start to use all of the available cpu and ramps up the temps and the fans. These programs are sometimes different but the latest was the System using over 60% of cpu, but still letting other programs use the cpu, but it ramps up to 100% constantly.

System Interrupts using 30 - 100% CPU

Hi Bradley. I'm Greg, an Independent Advisor here to help until this is resolved.

1) See fixes for System Interrupts causing high CPU usage:

2) Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed
in Device Manager reached by right clicking the Start button. Make sure you have the latest Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Then type System Information in Start Search, compare the latest BIOS/UEFI firmware version with the one showing in System Information, and install it following closely the instructions on the download page, and on any Read Me file included in download.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

3) Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 17 to test a new Local Admin account. Then if necessary
continue with the other steps to go over your install most thoroughly.

4) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, is the most stable method to advance to the latest version,
and solves most problems.

I hope this helps. Based on the results you report back I may have other suggestions if necessary. If you will wait to choose whether the problem is resolved, then I will continue to help until the problem is fixed.

Windows 11 - 100% CPU usage

Thanks for the suggestion regarding using Clean Boot to solve the problem.

I've done this and have confirmed no other apps are running, including removing virus protection.

The system is still running at 100% CPU.

Any other suggestions or things to check?

Thank you!

 

System Interrupts using 30 - 100% CPU

My brand new laptop keeps running extremely slow and task manager says system interrupts is using up most of my CPU. I've looked online and it says to update windows and drivers which I have done and nothing happens. I've contacted customer service but
its so bad that the automated chatbot doesn't even reply and when I call to speak to a real person they say nothing to help. Surely system interrupts should not be using 100% CPU?
