If Fortnite crashes your PC with a blue screen error (WHEA_UNCORRECTABLE_ERROR) only when joining a match, you’re dealing with a hardware-level stability issue, not a normal game crash. This problem is especially common on Ryzen CPUs paired with NVIDIA RTX GPUs, where Fortnite’s unique load pattern exposes hidden instability.
What Is WHEA_UNCORRECTABLE_ERROR in Fortnite?
WHEA stands for Windows Hardware Error Architecture. When this error appears, Windows is reporting a fatal hardware error that it cannot recover from.
Key signs this issue is Fortnite-specific:
NBA 2K26 – PlayStation 5
- Fortnite launches normally
- Menus and item shop work fine
- Blue screen happens only when entering a match
- Other games and applications run without issues
This behavior confirms the issue is triggered by Fortnite’s gameplay load, not by Windows corruption or GPU failure.
Fix 1: Disable CPU Boost (Most Effective Solution)
Ryzen 3000-series CPUs are known to crash under sudden boost spikes, especially in Fortnite.
Steps:
- Restart your PC and enter BIOS
- Find Precision Boost Overdrive (PBO)
- Set PBO = Disabled
- If available, disable Core Performance Boost
- Save changes and reboot
This fix alone resolves the issue for most players.
Fix 2: Disable XMP / DOCP Memory Profile
Even stable RAM can fail under Fortnite’s live match load.
Steps:
- Enter BIOS
- Locate XMP or DOCP
- Set it to Disabled
- Save and reboot
If this fixes the crash, your RAM overclock is unstable. You can later re-enable XMP and manually lower the memory speed.
Fix 3: Update Your Motherboard BIOS
Older BIOS versions have known instability issues with:
- Ryzen 3000 CPUs
- RTX 30-series GPUs
- PCIe communication
Steps:
- Identify your motherboard model
- Visit the manufacturer’s website
- Install the latest BIOS with updated AGESA
- Reset BIOS settings to default after update
This step is critical if your BIOS hasn’t been updated in the last year.
Fix 4: Manually Set CPU Voltage (Advanced Fix)
If disabling boost does not help, manual voltage control can stabilize burst loads.
Recommended settings:
- CPU Core Voltage: Manual
- Start with 1.25V
- Do not exceed 1.325V
This prevents voltage drops that cause WHEA errors during Fortnite matches.
Fix 5: Perform a Clean NVIDIA Driver Install
Driver conflicts can worsen hardware instability.
Steps:
- Use Display Driver Uninstaller (DDU) in Safe Mode
- Remove all NVIDIA drivers
- Install the latest driver using Custom Install
- Do not install GeForce Experience
Fix 6: Check Power Supply Stability
Sudden GPU power spikes during match loading can cause crashes if the PSU is borderline.
Recommended specs:
- Minimum 650W
- From a reputable brand
- Good transient response
If your PSU is old or low quality, replacement may be necessary.
What Will NOT Fix This Error
The following actions do not resolve WHEA errors caused by Fortnite:
- Reinstalling Fortnite
- Resetting Windows
- Running disk cleanup
- Updating drivers alone
- Changing power outlets
This is not a software corruption issue.
How to Confirm the Fix
After applying the fixes:
- Launch Fortnite
- Join multiple matches
- Monitor for blue screens
If the crash is gone, the issue was hardware instability triggered by Fortnite’s load behavior.
A WHEA_UNCORRECTABLE_ERROR in Fortnite does not mean your hardware is faulty. In most cases, it means your system needs better stability tuning, especially on Ryzen-based PCs.More Game Error Fixes
Disabling CPU boost, correcting RAM profiles, and updating BIOS resolve the issue for the majority of affected players.
