WHEA Uncorrectable Error Windows 10 Fix

The WHEA_UNCORRECTABLE_ERROR in Windows 10 is a Blue Screen of Death (BSOD) that usually points to a hardware problem or low-level driver issue.

It often involves the CPU, RAM, motherboard, or power supply, and sometimes even driver or BIOS misconfiguration.

🔧 What Causes the WHEA_UNCORRECTABLE_ERROR?

  • 🔌 Overheating or hardware failure (especially CPU)

  • 🧠 Faulty RAM or corrupted memory.

  • ⚙️ Driver conflicts or outdated drivers.

  • 🔋 Failing PSU (power supply).

  • 🧩 BIOS/UEFI misconfigurations or outdated firmware

  • ⚡ Voltage or clock missettings (especially if overclocked)

✅ How to Fix WHEA_UNCORRECTABLE_ERROR (Step-by-Step)

🔹 1. Check for Windows Updates

Outdated drivers or patches can trigger hardware-level errors.

Steps:

  • Go to Settings > Update & Security > Windows Update

  • Click Check for updates

  • Install everything and reboot

🔹 2. Undo Overclocking (If Applied)

Overclocking is one of the most common causes of this error.

Fix:

  • Reboot into BIOS/UEFI (usually press DEL, F2, or F10 at boot)

  • Set CPU/RAM clock and voltage to default or Auto

  • Save and exit BIOS

🔹 3. Run Windows Memory Diagnostic

Faulty RAM can cause this BSOD.

Steps:

  • Press Windows + R, type: mdsched.exe, press Enter

  • Choose Restart now and check for problems

  • Let the test run. If errors are found, you may need to replace the RAM.

🔹 4. Update All Drivers (Especially Chipset, GPU, and Storage)

Outdated or buggy drivers are a top software-related cause.

🛠 Easiest Way:

Use Device Manager or a tool like Driver Booster, or manually download from:

  • Intel/AMD chipset drivers

  • NVIDIA/AMD/Intel GPU drivers

  • Storage controller drivers (SATA/NVMe)

🔹 5. Check Hard Drive Health (For SSD/HDD Failures)

Failing drives can cause hardware-level errors.

Run CHKDSK:

  • Open Command Prompt as Admin

  • Run:

    chkdsk /f /r

Then restart.

Run SMART test:
Use CrystalDiskInfo or run this in Command Prompt:

wmic diskdrive get status

If it says “Bad,” replace the drive.

🔹 6. Check CPU Temps (Overheating Can Trigger WHEA)

Overheating can cause uncorrectable hardware errors.

Steps:

  • Use tools like HWMonitor or CoreTemp

  • If CPU temps are consistently above 90°C, clean your PC, reapply thermal paste, or improve airflow

🔹 7. Reset BIOS to Default

Misconfigured BIOS can cause voltage or timing errors.

Steps:

  • Reboot into BIOS (press DEL or F2 at boot)

  • Choose Load Optimized Defaults or Reset to Default Settings

  • Save and exit

🔹 8. Run System File Checker

Corrupted system files can sometimes be behind this.

Run in Command Prompt (Admin):

sfc /scannow

Wait for it to finish and follow any instructions.

🔹 9. Check for Power Issues

Failing Power Supply Units (PSUs) can trigger random BSODs.

  • If you recently installed a new GPU or CPU, make sure your PSU can handle it.

  • Test with a different PSU if possible.

🔹 10. Perform a Clean Boot

To rule out third-party services or drivers:

Steps:

  • Press Windows + R, type: msconfig

  • Go to Services tab, check Hide all Microsoft services

  • Click Disable all

  • Go to Startup tab → Open Task Manager → Disable all

  • Reboot

See if the BSOD persists. If not, a startup service or driver is likely the culprit.

🛑 LAST RESORTS

🔁 System Restore

Roll back to a previous state when your PC was working fine.

🧼 Reset Windows (Fresh Install)

If nothing else works, reset Windows with:

  • Settings > Update & Security > Recovery > Reset this PC
