Safe next steps
- For 0x00000143 (PROCESSOR_DRIVER_INTERNAL), record the stop code, parameters and any hardware error record or OEM diagnostic result.
- Check the exact PC maker’s hardware, thermal and firmware guidance before changing components. The bug-check name alone cannot identify a replaceable part.
- Stop repeated high-load testing if the device overheats, powers off or cannot preserve important files.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
