Windows 10: Windows 10 2004 issue with system interrupts at 100 percent cpu

Since installing Window 10 release 2004, I constantly have to reboot desktop PC after system interrupt begins running at 100 percent cpu. Desktop is HP p6-2220t processor Intel Pentium G640 2.80Ghz, 8 GB ram, 64-bit os. Had no problems at all running build 1909. Any suggestions would help.

Windows 10 System Interrupts 100% CPU Usage

After updating my graphics driver on my Lenovo computer, it started freezing after 1 to 2 minutes after booting. I was able to find out system interrupts is taking up 100% of the CPU.

 

System interrupts 100% CPU usage

I've been having an intermittent problem for a while now whereby Windows 10 (build 18362.418) will become completely unresponsive for about a couple of minutes. If I'm quick and launch Task Manager after it becomes responsive I can see that the System Interrupts
entry is using 100% CPU. I've heard that this can be caused by buggy drivers but I have no idea how I would go about verifying that this is the case or identifying which driver is responsible. Can anyone help?

 

100% CPU usage while on AC power - System Interrupts problem

I have been having the same issue that others have been experiencing
here, here, and here.
When you search for this you see
many results.

My symptoms:

- On battery power, computer behaves "normally".

- Immediately after plugging AC charger in, Task manager reports 100% CPU usage and never drops from that. The fan on my laptop runs constantly because of this.

The culprits in the Task Manager appear to be "System", "System Interrupts" and "Desktop Window Manager". See this screenshot:





The CPU usage of these three tasks jumps up and down between 30% and 0%, but the total CPU usage is always reported as 100%.

Steps I have taken:

1. Restart in safe mode (same issue)

2. The steps outlined in this post

3. Restart many other times.

4. Remove peripheral hardware.

I ran performance monitoring as outlined in this post. I can link the results from a shared OneDrive folder
if that would be helpful.

Here is a screenshot from that:





Where my mouse is (around 6 seconds in) is when I plugged in my laptop. There is a small spike in System (4) processes, but those go back down. When looking at task manager during this time, CPU usage is at 100%, but this performance trace does not report
the same thing as seen here:





Any help would be appreciated!!
