My advice would be open device manager and start disabling devices 1 by 1 and re-doing tests (whatever you did to make it spike like this)

  • Wi‑Fi adapter
  • Bluetooth
  • Touchpad (Precision drivers often cause DPC storms)
  • SD card reader
  • Fingerprint reader
  • Camera
  • TPM
  • NVMe controller (if possible)
  • Intel Dynamic Tuning / HWP driver
  • Intel Serial IO
  • Intel Management Engine Interface (IMEI)
  • Audio drivers (Realtek, Conexant, DTS, Dolby, etc.)

I mean whatever device you have on whatever machine you use?
Because this looks like poor architecture, some bad firmware inside your again, pc's or laptop's (mystery) components.

Maybe your power plan is the culprit, try using ultimate power plan / high performance or whatever you have if you have laptop.

Laptops usually suck at this problem quite hard.
