Step 1: Check Hardware Connections Carefully
The WHEA error often happens because of hardware issues. So, the first step is to check inside your system.
- Turn off the PC and unplug all power cables.
- Open your CPU cabinet slowly and safely.
- Remove RAM, SSD, graphics card, and all internal parts.
- Wait for at least two minutes before reconnecting them.
- Place all parts back in the correct slot firmly.
Loose or dusty components can trigger this error. If you recently installed new hardware, remove it. New RAM, SSD, or GPU might not be fully compatible. This may cause hardware conflict and crash your system.
Also, check your system fans and temperature. Overheating can lead to serious blue screen issues. If the cooling fan is not working properly, replace it. Keeping your system cool helps prevent WHEA errors.
Step 2: Check Disk Health Using CHKDSK Tool
Disk errors can also cause WHEA crashes. Use the CHKDSK tool to scan and repair them.
- Open the Start menu and type Command Prompt.
- Right-click on it and choose Run as Administrator.
- In the black window, type this command:
chkdsk /r - Press Enter and allow the scan to start.
The scan may take time depending on disk size. It checks for bad sectors and tries to fix them. Once done, restart your computer to apply changes.
Step 3: Test RAM Health Using MemTest86
Faulty RAM is a major cause of WHEA errors. Windows Memory Diagnostic may miss some problems. So, use a better tool called MemTest86.
- Visit the official MemTest86 website.
- Download the ISO file and create a bootable USB.
- Restart your system and boot from the USB.
- Let the test run for at least two full passes.
If errors appear during the test, your RAM is faulty. You may need to replace it to avoid blue screens.
Step 4: Check and Update System Drivers
Faulty or outdated drivers are another reason for WHEA errors. You must check for driver problems and update them.
Method A: Use Device Manager
- Open the Start Menu and type Device Manager.
- Look for any yellow warning icons on devices.
- Right-click and select Update Driver.
Method B: Use Windows Update
- Go to Settings > Windows Update > Update History.
- Check if any updates failed or are pending.
- Install all available driver updates.
Method C: Use Driver Updater Tools
- Use tools like Driver Booster or Snappy Driver Installer.
- These tools scan and update all drivers automatically.
- Always download such tools from official websites.
Step 5: Stop CPU Overclocking and Reset Power Settings
Overclocking your CPU or GPU increases performance. But it can make your system unstable and cause WHEA errors.
To reset CPU usage manually:
- Go to Control Panel > Power Options.
- Select Change plan settings for High Performance.
- Click on Change advanced power settings.
- Expand the Processor power management tab.
- Set Minimum processor state to 99% or lower.
This change reduces pressure on the CPU. It helps avoid blue screens caused by overclocking.
Step 6: Reset BIOS Settings to Default
Overclocking is often enabled in BIOS settings. Resetting BIOS can remove all performance tweaks and restore stability.
- Shut down the PC and restart it.
- Press the BIOS key (F2, DEL, F10 – depending on your PC).
- Once inside BIOS, find the option to Load Optimized Defaults or Reset to Default.
- Save and exit BIOS.
This will remove all overclocking changes from BIOS.
Step 7: Update BIOS Firmware (Advanced Fix)
If BIOS is outdated, it may not support new hardware well. Updating BIOS can fix WHEA errors permanently.
- First, install CPU-Z tool and check BIOS version.
- Note down your Motherboard Model and BIOS version.
- Visit your motherboard brand’s official website.
- Search for your model and download the latest BIOS update.
- Format a USB drive and copy the BIOS update file.
- Reboot your system and enter BIOS again.
- Choose the option like EZ Flash, Q-Flash, or M-Flash depending on your motherboard.
- Select your USB and run the BIOS update.
Warning: Be careful while updating BIOS. Don’t turn off your PC during the update. This process is risky if not done properly.
Step 8: Check Windows Updates and History
Sometimes, failed Windows updates can trigger the WHEA error.
- Open Settings > Windows Update > Update History.
- Look for any failed or incomplete updates.
- Reinstall or re-download the updates if needed.
Also, avoid using the system if updates are being installed in the background. Restart your system after every update.
Step 9: Reset Your Windows System (Last Option)
If nothing works, resetting Windows may be your only solution. This process restores system files without changing your personal files.
To reset Windows 10:
- Go to Settings > Update & Security > Recovery.
- Click Get Started under Reset this PC.
- Choose Keep my files to save personal data.
To reset Windows 11:
- Go to Settings > System > Recovery.
- Click on Reset PC and select Keep my files.
This will reinstall fresh Windows system files. It will remove damaged drivers, faulty settings, and broken updates.
Tip: Always back up important files before a reset.
Step 10: Tips to Prevent WHEA Error in Future
- Avoid overclocking unless fully necessary.
- Keep BIOS and all drivers updated regularly.
- Clean your system inside to remove dust and heat buildup.
- Use a cooling pad or better fans for gaming laptops.
- Run full system scans every month using built-in tools
The Bottom Corner
Fixing the WHEA Uncorrectable Error can help your system go crash anytime. But with the right steps, you can fix it easily. Start by checking hardware, then fix disk and RAM issues.
Update drivers, reset BIOS, and avoid overclocking. Reset Windows only when nothing else works. Follow these tips and enjoy a stable Windows experience.
