Microsoft — Intel processor power management
When blamed in a crash: Often a victim, dig deeper
What to do
CPU power management driver. Crashes here track CPU/BIOS issues — or a leftover after switching between Intel and AMD hardware.
- Update the BIOS.
- Return CPU clocks/undervolts to stock.
- If this system's disk was cloned from an AMD machine (or vice versa), that mismatch is a known crash cause — reinstall Windows or remove the stale service.
