As Windows 10 and Windows 11 updated over the years, Microsoft changed how the operating system handles power management states (C-states). If your motherboard's BIOS is still running firmware from 2012 or 2013, it cannot properly translate the power instructions Windows is sending to the Ivy Bridge CPU. 2. Failing Hardware or Unstable Overclocks
This is the specific internal signature for the Ivy Bridge microarchitecture released around 2012. Common Processors in This Family acpi genuineintel---intel64-family-6-model-58
The hardware ID ACPI\GenuineIntel_-_Intel64_Family_6_Model_58 is a specific identifier used by Windows to communicate with a processor via the Advanced Configuration and Power Interface (ACPI). If you see this string in your Device Manager or system logs, you are looking at an processor. Decoding the ID As Windows 10 and Windows 11 updated over
If you ever encounter this string in your logs, take a moment to appreciate the decades of standards (ACPI, CPUID, x86-64) that silently work together—most of the time, perfectly. Failing Hardware or Unstable Overclocks This is the
microarchitecture (specifically the 22nm third-generation Intel Core series). Which CPU is this? If your system shows "Model 58," you are running a 3rd Generation Intel Core Processor . Common examples of this family include: Mobile (Laptops): Core i5-3230M, Core i7-3630QM Core i5-3570K, Core i7-3770
