How to Read WHEA-Logger Errors in Windows

By Iikka Isosaari · Windows 11 · Updated

WHEA stands for Windows Hardware Error Architecture.

When Windows detects certain hardware-level errors, it may create a WHEA event in Event Viewer.

Where to Find WHEA Events

Open:

Event Viewer → Windows Logs → System

Filter or search for:

WHEA-Logger

Corrected vs Fatal Errors

Some WHEA events describe corrected hardware errors.

This means the hardware or platform detected a problem but recovered from it.

A corrected error is not automatically a catastrophic failure, but repeated events deserve investigation.

Common Components

WHEA errors may reference:

PCI Express Errors

A PCIe-related WHEA event may point to a root port or connected device.

Possible causes can include:

The bus/device/function information can help identify the path involved.

CPU WHEA Errors

Processor-related WHEA events may occur because of:

Do Not Ignore Patterns

One corrected error months apart may be less concerning than hundreds every day.

Questions about How to Read WHEA-Logger Errors in Windows

Does a corrected WHEA-Logger event mean a component has failed?

Not necessarily. A corrected error means the platform recovered from a reported hardware error. Repeated events or crashes warrant investigation, but one event alone does not identify a failed part.

Does a PCI Express Root Port event prove the GPU is broken?

No. A root port may have several connected devices or links. Use bus, device and function details and the actual hardware path before narrowing the investigation.

What details should I keep for support?

Save the event ID and full message, frequency, timestamps, workload and accompanying symptoms. Those patterns are more useful than the red error icon alone.
