Run CPU stress tests

  1. Step 1: Download a reputable CPU stress testing tool such as Prime95 or OCCT from a trusted source.
  2. Step 2: Run the stress test on your system for an extended period to identify if the issue is related to thermal throttling or other performance-related issues.

🎯 Final Words

To resolve the hardware error, it's recommended to first update the BIOS to the latest version and then run CPU stress tests. If updating the BIOS doesn't resolve the issue, running stress tests may help identify the root cause of the problem. In some cases, a hardware issue with the CPU may require professional repair or replacement.
