Question Extremely high DPC latency (lag) anomaly

I just built a new computer and I’m experiencing DPC latency consistently (not spikes) at 100000 microseconds (extremely high) upon start up. This is “fixed” by hard rebooting my PC (holding down power button for 6sec). Regular shutdown when the problem is occurring will turn off the screen but all LEDs and fans continue to run. Regular restart will buffer for several minutes and eventually error saying some component ignored shutdown signal. After this hard reboot, the subsequent start up always works perfectly fine with DPC maxing out at 1000. When I go to shutdown/sleep (which works as expected) the next startup has the issue again.


components:
Mobo: Asus Strix x570 i gaming
Cpu: yzen 7 3700x
Graphic card: Asus 1060 3Gb

All drivers and bios are up to date. Graphic card drivers have been clean reinstalled. No error lights on my mobo.
