Troubleshooting Windows 11 NMI_HARDWARE_FAILURE BSOD on HP ProBook 445 G8: Next Steps After Memory Testing
Experiencing Blue Screen of Death (BSOD) errors can be a frustrating challenge for Windows users, especially when the error points to hardware issues. Recently, users have reported encountering the NMI_HARDWARE_FAILURE BSOD on Windows 11 devices, including the HP ProBook 445 G8. When troubleshooting such errors, it’s essential to adopt a systematic approach to identify the root cause. This article discusses key steps to consider after confirming that RAM isn’t the culprit.
Understanding the Context and Initial Tests
In cases where the NMI_HARDWARE_FAILURE error appears, the first step is often to assess whether memory-related issues contribute. Running a comprehensive memory test with tools like MemTest86 can provide clarity. For instance, in a recent scenario, a user ran MemTest86 for approximately four hours, passing all 48 tests without errors. This effectively rules out faulty RAM as the source of instability.
However, during the memory testing phase, the user observed CPU temperatures rising significantly—from about 63°C up to 100°C, with an average around 71°C. While these temperatures are not unusual during intensive testing, such high readings can potentially lead to thermal-related system failures and warrant further examination.
What Should Be Checked Next?
After confirming memory health, users should consider other hardware components and system factors that could trigger the NMI_HARDWARE_FAILURE BSOD. Below are key areas to investigate:
1. Overheating and Cooling Efficiency
-
Thermal Management: Elevated CPU temperatures, especially approaching 100°C, can cause system instability. Ensure that cooling components such as fans are operational and unobstructed.
-
Thermal Paste: Consider reapplying thermal paste on the CPU if temperatures remain consistently high under normal workloads.
-
Cleaning Dust: Regularly clean dust from vents and fans to improve airflow.
2. Storage Device Health
-
SSD and HDD Checks: A failing or degraded storage drive can cause hardware errors. Use tools like CrystalDiskInfo or vendor-specific diagnostics to assess drive health.
-
Firmware Updates: Ensure your SSD firmware is up-to-date, as manufacturers often release updates to improve stability.
3. Power Supply and Battery Health
- Laptop Specifics: While desktops have readily
