WHEA_UNCORRECTABLE_ERROR (Stop 0x00000124)
Windows Hardware Error Architecture (WHEA) detected a physical hardware error that cannot be corrected by CPU or bus architecture.
Internal desktop parts run on harmless 12V DC voltage and cannot shock you. Simply unplug the wall power cable first, then touch the unpainted metal case frame to ground static electricity.
Common Symptoms & Tells
- Stop code 0x00000124 on crash screen
- Immediate reboot without writing dump file (0% progress)
- Triggered by high CPU/ loads or extreme thermal spikes
Interactive Fix Checklist
0 of 4 steps completedRemove CPU undervolts or overclocks
Enter and reset CPU Vcore, Load-Line Calibration (LLC), and PBO/Curve Optimizer settings to factory defaults. Insufficient core voltage is the #1 cause of WHEA errors.
Monitor CPU and VRM temperatures
Use HWInfo64 to ensure CPU temperature is below 90°C and motherboard VRMs are not thermal throttling under load.
Update motherboard BIOS for microcode patches
Motherboard vendors release updates containing Intel/AMD CPU microcode stability fixes to resolve internal bus parity errors. CRITICAL: Never turn off, reset, or unplug the PC while the update is flashing. A power interruption during EEPROM write will corrupt the firmware and brick the motherboard.
Test with an alternate power supply
Transient voltage dips from a failing or underpowered trigger internal CPU power-plane resets.
