The CPU DXE initialization phase is a crucial part of a computer’s boot process, where the system prepares the CPU and critical components for operation.
CPU DXE Initialization Is Started means the motherboard sets up the CPU, chipset, and essential components. Errors here often signal problems during the initialization process, impacting boot. Troubleshooting typically involves reseating hardware or updating BIOS.
This guide explains common DXE Initialization problems, solutions, and how they impact system performance.
What Does “CPU DXE Initialization” Mean?
In the UEFI BIOS structure, the boot process is divided into distinct stages: the SEC (Security), PEI (Pre-EFI Initialization), DXE (Driver Execution Environment), and BDS (Boot Device Selection) phases.
The DXE phase focuses on loading and initializing critical drivers for the CPU, memory, and essential peripherals.
When you see “CPU DXE initialization is started,” the BIOS attempts to initialize the CPU and related components before moving to the next step in the boot sequence.
Common Issues During CPU DXE Initialization
1. Code 67 and Other Error Codes:
Error code 67 frequently appears during the DXE phase, suggesting CPU or memory initialization issues. This error can result from misconfigured firmware, compatibility issues, or hardware faults.
To resolve it, you might need to adjust BIOS settings, check the configuration of installed components, or update the system’s firmware or drivers.
2. Power Supply and Cooling Issues:
Insufficient power or improper cooling may interrupt the DXE initialization process. Ensuring a stable power supply to the CPU and confirming that cooling components are functioning (like the CPU fan or water pump) can help avoid overheating issues that trigger errors during this stage.
3. Incompatible or Misconfigured Hardware:
Hardware compatibility, especially with RAM, is crucial during CPU initialization. The initialization process can only succeed if the CPU or memory modules are compatible or correctly seated.
In such cases, reseating RAM modules, using fewer RAM sticks during troubleshooting, or verifying that components match motherboard specifications may help.
Troubleshooting Steps for CPU DXE Initialization Issues
1. Reset BIOS Settings:
Restoring BIOS to default settings can often resolve initialization problems, as custom configurations may interfere with the DXE phase. Access the BIOS setup, select the “Restore Defaults” option, and reboot to test for resolution.
2. Update Firmware and Drivers:
Outdated firmware or drivers can lead to DXE initialization errors. Check the motherboard manufacturer’s website for BIOS updates, and apply the latest firmware and driver updates to ensure compatibility with newer hardware.

3. Check Hardware Compatibility:
Verify that the CPU, RAM, and other components are compatible with the motherboard. Cross-referencing the hardware’s supported configurations on the motherboard’s specifications page can help identify potential compatibility issues.
4. Inspect Physical Connections:
Ensure all physical connections, such as CPU socket pins and RAM modules, are secure. Bent or misaligned pins in the CPU socket can cause initialization issues and may require professional inspection or correction.
5. Verify Cooling System:
Ensure the CPU cooler is mounted correctly and all cooling fans or water pumps function. Adequate cooling is essential during the DXE phase, as overheating can lead to early-stage shutdowns.
6. Check the Power Supply:
If the power supply is insufficient or failing, it may struggle to support the CPU initialization process. Verify that the power supply meets your system’s requirements and check all connections to ensure proper power delivery.
How BIOS and Firmware Updates Affect DXE Initialization
- Importance of Updates: Updates often resolve compatibility issues, stabilize memory settings, and address bugs that cause DXE errors.
- Update Procedure: Methods such as USB BIOS Flashback allow users to update firmware even if the system cannot boot.
Preventing Future DXE Initialization Errors
To minimize the risk of encountering CPU DXE initialization errors in the future, consider the following maintenance tips:
- Regularly Update BIOS and Drivers: Keep the system’s BIOS and drivers current, as manufacturers frequently release updates to address compatibility and stability issues.
- Monitor System Temperature and Power: Maintain efficient cooling and use a reliable power supply to prevent power-related disruptions during boot.
- Verify Hardware Compatibility: When upgrading components, always verify their compatibility with your existing system to avoid initialization conflicts.
