WHEA_UNCORRECTABLE_ERROR is one of the more serious blue screen errors because it typically indicates a hardware problem. Here’s how to diagnose and fix it.
What is WHEA_UNCORRECTABLE_ERROR?
WHEA stands for Windows Hardware Error Architecture. This error (Stop Code 0x00000124) occurs when Windows detects an unrecoverable hardware error that it can’t fix or ignore.
Common Causes
Hardware-Related (Most Common):
- Overheating - CPU or GPU running too hot
- Overclocking instability - Unstable overclock settings
- Failing CPU or GPU - Hardware degradation
- Faulty RAM - Memory errors
- Power supply issues - Insufficient or unstable power
- Motherboard problems - Failing components
Software-Related (Less Common):
- Outdated BIOS - Incompatible with hardware
- Driver conflicts - Usually chipset or GPU drivers
- Windows corruption - Damaged system files
Why This Error Is Serious
Unlike many blue screens that are software-fixable, WHEA errors often mean:
- Hardware is failing or has failed
- The problem may get worse over time
- Data loss risk if storage is affected
- May require component replacement
Immediate Steps
Step 1: Note the Error Details
Before restarting, note any additional information on the blue screen:
- Parameter codes (like 0x00000000)
- Any file names mentioned
- When the error occurred (during what activity)
Step 2: Check for Overheating
Overheating is the most common cause:
Quick Check:
- Feel the computer’s vents - are they very hot?
- Is the fan running constantly at high speed?
- Did the crash happen during intensive tasks?
Proper Check:
- Download HWiNFO or Core Temp
- Monitor temperatures during normal use
- CPU should stay below 85°C (185°F)
- GPU should stay below 90°C (194°F)
If Overheating:
- Clean dust from fans and vents
- Ensure proper airflow around computer
- Replace thermal paste if old (3+ years)
- Consider better cooling solutions
Step 3: Disable Overclocking
If you’ve overclocked CPU, GPU, or RAM:
- Enter BIOS/UEFI (press Del or F2 during boot)
- Load Default or Optimized Settings
- Save and exit
- Test for stability
Even factory-overclocked systems can be unstable:
- MSI Afterburner - reset to default
- Intel XMP - try disabling
- AMD EXPO - try disabling
Hardware Diagnostics
Test Your RAM
Bad RAM is a common culprit:
- Press Windows + R, type
mdsched, Enter - Click Restart now and check for problems
- Let the full test complete
If errors found:
- Test each RAM stick individually
- Try different RAM slots
- Replace faulty modules
Check Drive Health
Failing storage can trigger WHEA errors:
- Download CrystalDiskInfo
- Check the Health Status
- Look for warning indicators
- If issues found, back up data immediately
Check GPU Health
Graphics card problems cause WHEA errors:
Symptoms of failing GPU:
- Artifacts (strange visual glitches)
- Crashes during games or graphics work
- Driver crashes and recoveries
- Fan running at full speed constantly
Test your GPU:
- Run FurMark or 3DMark
- Monitor temperatures and behavior
- Watch for crashes or artifacts
Check Power Supply
Insufficient power causes instability:
Signs of PSU problems:
- Random shutdowns or restarts
- Crashes under heavy load
- Burning smell from computer
- Multiple component failures
Solutions:
- Ensure PSU wattage is sufficient
- Test with a known-good PSU
- Replace if suspected faulty
Software Fixes
Update BIOS
Outdated BIOS can cause hardware errors:
- Check current BIOS version (System Information)
- Visit manufacturer’s website
- Download latest BIOS
- Follow update instructions carefully
Warning: Don’t interrupt BIOS updates. Power loss during update can brick your motherboard.
Update Chipset Drivers
Outdated chipset drivers cause WHEA errors:
For Intel:
- Visit intel.com
- Download Intel Driver & Support Assistant
- Install recommended updates
For AMD:
- Visit amd.com/support
- Download chipset drivers for your motherboard
- Install and restart
Run System File Checker
Repair Windows files:
- Open Command Prompt as Administrator
- Run:
sfc /scannow - Then:
DISM /Online /Cleanup-Image /RestoreHealth - Restart
Check Event Viewer
Find more details about the error:
- Open Event Viewer
- Go to Windows Logs > System
- Look for WHEA-Logger events
- These contain detailed hardware error information
When Hardware Replacement Is Needed
Signs You Need New Hardware
CPU issues:
- Errors occur during CPU-intensive tasks
- Temperatures normal but still crashing
- Multiple BSODs with CPU-related codes
GPU issues:
- Errors during graphics tasks
- Visual artifacts appear
- Driver crashes frequently
RAM issues:
- Memory diagnostic finds errors
- Errors at random times
- Multiple different BSOD codes
Motherboard issues:
- Multiple components seem faulty
- Errors with various hardware
- USB ports or slots not working
Professional Diagnosis
If you’re unsure which component is failing:
- Professional diagnostic tools can identify the problem
- Stress testing can reveal unstable components
- Thermal imaging can find hot spots
WHEA Errors Keep Crashing Your PC? Our Dallas technicians have professional diagnostic equipment to identify failing hardware. We test CPUs, GPUs, RAM, and power supplies to find the exact problem. Same-day service throughout DFW.
Preventing WHEA Errors
- Keep your computer cool - Clean regularly, ensure good airflow
- Don’t overclock unless you know what you’re doing
- Use a quality power supply - Don’t cheap out on PSU
- Keep BIOS and drivers updated
- Use a surge protector - Power spikes damage hardware
- Monitor temperatures - Catch problems early
Cost Considerations
If hardware replacement is needed:
- RAM: $30-150 depending on type and capacity
- GPU: $150-1500+ depending on model
- CPU: $100-500+ depending on model
- PSU: $50-150 for quality unit
- Motherboard: $100-400+ depending on features
Sometimes it’s more economical to upgrade the whole system.
