WHEA Logger Errors in Windows Event Viewer

When using Windows, you may encounter various system errors that are logged in the Event Viewer. One common issue is the WHEA Logger error (Windows Hardware Error Architecture Logger). These errors typically indicate hardware issues and can be a sign of underlying problems that need attention, especially if they appear frequently. In this guide, we’ll explain what WHEA Logger errors are, why they occur, and how to fix them.

What is WHEA Logger?

The WHEA Logger is a component of Windows designed to log hardware errors related to components such as the CPU, RAM, or motherboard. These errors often stem from hardware malfunctions, incorrect drivers, BIOS issues, or improper system settings.

Common WHEA Logger Errors

  • WHEA-Logger Event ID 17: Indicates memory-related errors, often involving ECC (Error-Correcting Code) memory issues, which may suggest faulty RAM.
  • WHEA-Logger Event ID 19: Reports errors related to CPU malfunctions, frequently caused by overheating or incorrect frequency settings.
  • WHEA-Logger Event ID 20: Represents critical errors that might be associated with hardware failures such as issues with hard drives or SSDs.

Causes of WHEA Logger Errors

WHEA Logger errors can occur due to several reasons, including:

  1. CPU Overheating: High CPU temperatures, especially under heavy load, can cause system instability and trigger these errors.
  2. Incorrect BIOS Settings: Overclocking or improper power settings in BIOS may lead to hardware errors.
  3. Faulty RAM: ECC memory errors often point to defective RAM modules.
  4. Driver Issues: Outdated or incompatible drivers can disrupt hardware functionality and generate errors.
  5. Hardware Defects: Problems with the motherboard, hard drive, or SSD can also be sources of WHEA Logger errors.

How to Fix WHEA Logger Errors

Follow these steps to resolve WHEA Logger errors:

1. Check CPU Temperature

Use tools like HWMonitor or Core Temp to monitor CPU temperatures. If the temperatures exceed safe limits (typically above 80-90°C), improve your cooling setup, replace thermal paste, or reduce system load.

2. Reset BIOS Settings

If you have enabled overclocking, try resetting BIOS settings to their default values. This can help resolve issues related to improper voltage or frequency configurations.

3. Test RAM for Errors

Use the Windows Memory Diagnostic tool or MemTest86 to check your RAM for issues. If errors are detected, consider replacing the faulty memory modules.

4. Update Your Drivers

Ensure that all drivers are correctly installed and up to date. Pay special attention to chipset drivers and any drivers related to CPU functions.

5. Check the Hard Drive or SSD

Run diagnostics using tools like CrystalDiskInfo or HD Tune to assess the health of your drives. If errors are found, the drive may need to be replaced.
