Fix 0xC0262116: Graphics Allocation Content Lost on Windows

You're running a game or a GPU-accelerated app—maybe Cyberpunk 2077, a Blender render, or a video encode job—and suddenly it crashes with error 0xC0262116 (ERROR_GRAPHICS_ALLOCATION_CONTENT_LOST). The screen might freeze for a second, then the app closes. This error means the graphics driver or the GPU itself lost the contents of a video memory allocation. In plain English: the data the app stored on the GPU vanished before it was used.

What Causes This Error

The culprit here is almost always a driver timeout or a GPU hang. When the display driver doesn't respond to Windows for more than 2 seconds, the OS resets the driver stack. That reset invalidates all existing video memory allocations. So the app gets back a message saying, “Hey, that memory you allocated? Gone.” The app doesn't handle this gracefully—hence the crash.

Other triggers: overclocked GPU (especially VRAM), faulty power supply causing voltage drops, or a buggy app that allocates memory incorrectly. On laptops, switching between integrated and discrete GPUs can also cause this if the app doesn't handle adapter loss properly.

How to Fix It

1. Update or reinstall your graphics driver. Use Display Driver Uninstaller (DDU) in Safe Mode to wipe the current driver. Then install the latest driver from NVIDIA, AMD, or Intel. Skip the “Game Ready” bloat—just get the standard driver. Reboot after.
2. Disable GPU overclocking. If you've overclocked the core or memory clocks, revert to stock. Use MSI Afterburner or your GPU vendor's tool. Set memory clock to default, core clock to default. Test the app again.
3. Increase TdrDelay registry value. This gives the driver more time before Windows resets it. Open Regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers. Create a DWORD named TdrDelay if it doesn't exist, set its value to 10 (decimal). Reboot.
4. Check VRAM usage. Open Task Manager Performance tab, look at GPU memory usage. If your app eats more than 90% of VRAM, reduce texture quality or resolution. Some apps have memory leaks—close and restart the app if usage climbs over time.
5. Run a GPU stress test. Use FurMark or Unigine Heaven for 15 minutes. If it triggers the error, your GPU may be unstable. Check temperatures—keep under 85°C for NVIDIA, 90°C for AMD.
6. Reinstall the app. Sometimes the app itself has corrupted config files. Uninstall it, clear leftover folders in %appdata% and %localappdata%, then reinstall.

If It Still Fails

Try these in order:

• Update Windows to the latest version—especially cumulative updates that include graphics fixes.
• Test with a different GPU if you have one. Borrow a friend's card if possible.
• Check your power supply wattage and stability. A 550W PSU for a 3070 is marginal—go higher.
• Run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to repair system files.
• If nothing works, the GPU might have hardware memory corruption. Run GPU-Z and check the memory vendor (Samsung, Micron, Hynix). Some batches of RTX 3080s with Micron memory had faulty VRAM that triggers this exact error.

This error is fixable in 90% of cases with a clean driver install and a TdrDelay tweak. Don't bother reinstalling Windows—that's a waste of time unless you've already tried everything else.
