Postup řešení

  1. 1 Restart your PC and press the key to enter BIOS/UEFI (usually Del, F2, or F10). Look for settings related to CPU, such as 'Intel SpeedStep', 'AMD Cool'n'Quiet', or 'C-State'. Disable any power-saving features that might affect processor synchronization. Save and exit.
  2. 2 If you recently overclocked your CPU, reset the BIOS to default settings. In BIOS, look for 'Load Optimized Defaults' or 'Reset to Default'. This ensures the processor runs at its intended settings.
  3. 3 Check if your CPU is compatible with Windows 11. Microsoft has a list of supported processors. If your CPU is not on the list, you may need to upgrade your hardware.
  4. 4 Update your BIOS to the latest version. Visit your motherboard manufacturer's website, download the BIOS update, and follow their instructions. This can fix compatibility issues with multi-core processors.
  5. 5 If the error occurs during Windows installation, try disabling one core in BIOS (if possible) to see if the installation completes. Then re-enable it after installation.
  6. 6 Run Windows Memory Diagnostic (mdsched.exe) to rule out RAM issues, as faulty memory can cause processor configuration errors.
