Bug check 0x000001E4 (VIDEO_DXGKRNL_SYSMM_FATAL_ERROR) is a fatal crash in Windows' DirectX Graphics Kernel system memory manager. This is the component that manages how the GPU and system share memory.
This BSOD is directly related to GPU operations and is more common on newer Windows versions.
How to fix it:
- DDU clean install GPU driver — this is the most important step. Boot into Safe Mode, run DDU, install the latest stable driver
- Disable any GPU overclock, including memory overclock — VRAM instability directly causes this
- Make sure Windows is fully updated — Microsoft patches DXGK components through Windows Update
- Disable Hardware-Accelerated GPU Scheduling: Settings > System > Display > Graphics > Change default graphics settings
- Run OCCT VRAM test to check for GPU memory errors
- Try an older GPU driver if the crash started after a driver update
- Check GPU temperatures — overheating can cause VRAM instability
- If the BSOD persists across multiple driver versions and Windows is updated, the GPU VRAM may be failing
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
