Windows 10: 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?

System Interrupts 100% CPU 0

Hi.

I have a an i7-6700 - Lenovo AIO 700 27ISH

CPU 0 is always 100% with System Interrupts. 15% CPU overall. Fan runs high. CPU constant overclock to 3.97 from base 3.41

ACPI.sys appears to be what is using the CPU under System Interrupts.

Complete fresh install of Windows 10 1909.

Nothing else open.

Tried updating all drivers and applying OEM drivers.

Safe Mode is the same.

Disabled every device I could but no change.

Disabled power saving on any device I could.

Disable wake on magic packet for LAN and Wi-Fi.

I'm thinking that it must be an actual hardware fault as it occurs even in Safe Mode and that I can't think of anything else to try. If it is a hardware fault, is there some way I can pin down what the hardware fault is?

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.
