Fix OBS Studio on Windows: Black Screen, No Audio, Crashes
Try the quick fixes below. Start from the top and test after each change. If you only need the installer, grab it here:
Black screen (Game/Display Capture)
- Laptops (hybrid GPU): Assign OBS to the high‑performance GPU (Windows → System → Display → Graphics → Add OBS → High performance).
- Match capture: Use Display Capture for desktop apps, Game Capture for fullscreen games. For DX12 titles, try Window Capture or borderless windowed mode.
- Disable overlays: Turn off Discord, Steam, GeForce Experience, Xbox Game Bar overlays, and other hook‑based tools.
- Run as admin: Right‑click OBS → Run as administrator.
No audio (mic/desktop)
- Settings → Audio: Confirm devices and Sample Rate 48 kHz. Avoid duplicates in Advanced Audio Properties.
- Windows defaults: Check Sound → Output/Input defaults and levels; disable Exclusive Mode in device properties if needed.
- Monitoring: Use Monitor and Output for mic checks; ensure the correct track is selected for streaming/recording.
Encoder overloaded / High CPU
- Switch to NVENC (new), QSV, or AMF if available.
- Lower x264 preset (e.g., veryfast → superfast) or reduce Output (Scaled) Resolution.
- Drop to 30 FPS and close background tasks.
Crashes or freezes
- Update GPU drivers (clean install if issues persist).
- Temporarily remove third‑party plugins; update to latest OBS.
- Disable overlays and run OBS as administrator.
- Review Help → Log Files for crash details and conflicts.
Quick test checklist
- Create a new Scene and add Display Capture + Mic.
- Hit Start Recording for a 30‑second test; review video and audio levels.
- If stable, try Start Streaming to a private/unlisted target.
