What is TDR-EVENT?
Display driver stopped responding and recovered is a high-severity graphics card (GPU) issue. Timeout Detection and Recovery (TDR) was triggered because the GPU did not respond within the allocated time, forcing Windows to reset the display driver. Typical causes include unstable GPU core or memory overclock and GPU overheating under load. Work through the steps below in order.
Common Causes
- Outdated or corrupted graphics driver
- Unstable GPU core or memory overclock
- GPU overheating under load
Step-by-Step Fix Guide
-
1
Perform a clean driver reinstall using DDU
The highest-success first step is Perform a clean driver reinstall using DDU, which targets the most common trigger behind TDR Event.
-
2
Reset all GPU overclocks to defaults
Repeat occurrences typically trace back to less obvious gpu instability factors, addressed in the steps ahead.
-
3
Increase TdrDelay registry value to 8
Try "Increase TdrDelay registry value to 8" next if the issue persists — it addresses a secondary cause.
Commands & Diagnostics
reg add HKLM\System\CurrentControlSet\Control\GraphicsDrivers /v TdrDelay /t REG_DWORD /d 8 /f
Frequently Asked Questions
TDR-EVENT is most often triggered by outdated or corrupted graphics driver. Other reports point to unstable GPU core or memory overclock and GPU overheating under load as contributing factors.
"Perform a clean driver reinstall using DDU" clears up most TDR-EVENT reports by itself. The remaining steps above cover what's left.
Rated high severity — TDR-EVENT isn't immediately destructive, but recurring instances are a sign to fix it sooner rather than later.
In most cases, yes — the guide above resolves TDR-EVENT without a clean install. Treat a reinstall as the last resort, not the first move.
Yes — GPU or memory overclocking is one of the most frequent triggers for TDR-EVENT. Try resetting your GPU to stock clocks using MSI Afterburner or your OC software, then test for stability before investigating other causes.
