100% CPU usage at idle

[purplekinght]

For the past 3 to 4 days I have been battling with my cpu. At idle it seems to be using 100% at idle. I have am i7 9700k , 32gbs of ram , Rtx 2080 and Z390 gaming pro carbon.

Here are the things I've tired 

1 resting my pc

2 updating MB bios 

3 multiple antivirus scans 

4 updating MS 

5 changing power options to ultimate 

6 scanned for corrupted files with cmd

7 reinstalling windows

8 downloaded intel's extreme tuning utility ( which says everything is fine )

and nothing has worked so far and I need your help.

@purplekinght do a full clean install of windows erase everything off your drives and re Install a fresh windows don't go through the windows option. Do it through a flash drive
