📒 HWInfo - System Log Diagnostics: Logging System Issues

This guide explains how to use HWInfo to capture system data for troubleshooting computer issues.

Why Use HWInfo for Diagnostics?

If a customer is experiencing issues (like crashes, errors, or freezing) but can’t clearly describe them, or if problems reappear after a recent service, HWInfo can log important system data for analysis. This allows us to troubleshoot remotely without the client bringing the system in.

  • The log file captures: crashes, errors, freezing events, temperature fluctuations, and other system anomalies.
  • Goal: Log any crashes or system issues so our team can analyze the data and determine the cause of the problem.

Getting Started

The client needs to download and install HWInfo to generate a system log file (CSV format) that they can send to us for review.

How to Enable Logging in HWInfo (PC)

1. Install and Open HWInfo

  1. Launch HWInfo64 (or HWInfo32 if on a 32-bit system).
  2. If prompted, select “Sensors-only” mode and click Run.

2. Open the Sensor Window

  • If the sensor window doesn’t open automatically, click the Sensors button (a small graph icon).

3. Enable Logging

  1. In the sensor window, press F2 or click the “Logging Start” button (a small disk icon with a red dot).
  2. Choose a location to save the log file (CSV format).
  3. Click Save to start logging.

4. Let HWInfo Run in the Background

  • Keep HWInfo running while using the computer normally to capture system events.
  • The program will continuously log sensor data to the CSV file.
  • Tip: If monitoring over a long period, you can adjust the logging interval in Settings → Safety → Logging Interval (default is $1000\text{ms}$).

5. Capture a System Issue

  • The goal is to log a crash or performance issue, even if it is temperature-related.

6. Send Us the Log File

  1. Once the system issue has been experienced while logging, email the saved CSV file to the support mailbox (e.g., support@example.com).
  2. The engineering team will analyze the logs to help diagnose the problem and will follow up with a report.
