System interupts causing high CPU usage, possibly from ataport.sys
I been working on this for a month now and have had no luck looking in other posts. System interrupts uses one core of my computer 100%. I ran windows performance analyzer and it seems to be caused by ataport.sys . The problem happens periodically and will last for a couple of hours then go away. I have ran an AVG full scan and Malwarebytes full scan. I've tried to update all my drivers. I'm not sure what else to do.
I will attach some links to trace files if anyone would be willing to look at them.
This is a trace file with system interrupts using low to no processor.

This is a trace file when system interrupts is using a high percentage of the processor.
