Fixing Computer Freezes When Launching Games in Full Screen

Your PC freezing when a game goes full screen is frustrating but usually fixable. The culprit is often one of several common issues. Follow this step-by-step guide to identify and resolve the problem.

1. Check System Resources

• RAM: Close background apps before launching. Low memory causes freezes.
• Overheating: Monitor CPU/GPU temperatures. Clean dust from fans and consider reapplying thermal paste.
• Disk Space: Ensure at least 15-20% free space for swap files and game assets.

2. Update or Reinstall GPU Drivers

• Download the latest drivers directly from NVIDIA, AMD, or Intel.
• If updates don't help, perform a clean installation using tools like DDU (Display Driver Uninstaller).
• Temporarily disable non-essential drivers (audio, etc.) to test for conflicts.

3. Eliminate Software Conflicts

• Antivirus/Firewall: Add the game as an exception or temporarily disable protection.
• Background Apps: Close unnecessary programs (browsers, Discord, Steam Overlay).
• Overlay Software: Disable Discord, GeForce Experience, Steam Overlay, and similar tools.

4. Test Hardware Health

• RAM: Run Windows Memory Diagnostic or MemTest86.
• Storage: Check SMART status and run chkdsk for drive errors.

5. Game-Specific Tweaks

• Update the game to the latest patch.
• Lower graphics settings (resolution, textures, shadows).
• Verify game file integrity via the launcher (Steam, Epic, etc.).

Recommended Troubleshooting Order

1. Close apps, check RAM and disk space.
2. Update GPU drivers.
3. Disable overlays and antivirus temporarily.
4. Reduce in-game settings.
5. Verify game files.
6. Run hardware diagnostics.

If the issue persists, share your system specs and the specific game on community forums (like r/techsupport or the game's subreddit) for targeted help.
