- GPU driver hang
- deadlock in game code
- storage I/O bottleneck
- insufficient CPU or RAM
How to fix it
- Update GPU driver
- move game to SSD
- close background apps
- check for game-specific freeze bugs

Event ID 1002 (Source: Application Hang) means an application froze and had to be killed. The 'Not Responding' state in Task Manager triggers this event when you end the task or Windows auto-terminates it.
For games, this typically means a freeze/hang rather than a crash.
How to diagnose:
- Open Event Viewer > Windows Logs > Application, filter by Event ID 1002
- The event shows which application hung and for how long
- Check if Event 4101 (GPU TDR) appears around the same time — if yes, the GPU driver hung first
How to fix game hangs:
- Update GPU driver — driver hangs are the #1 cause of game freezes
- Move the game to an SSD — slow storage causes loading freezes
- Lower graphics settings — an overloaded GPU can cause temporary hangs
- Monitor CPU and GPU usage during gameplay — if either hits 100%, reduce settings or close background apps
- Check for game-specific freeze bugs on the game's subreddit or forums
- Disable Shader Pre-Caching in Steam — shader compilation during gameplay causes micro-freezes
- Increase TDR timeout if GPU hangs are the cause
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
