I was running a product launch event yesterday when PowerPoint froze while playing a video on slide 3. The laptop was running Windows 11, was offline, had no other applications open, and had handled both the slides and video normally during rehearsal. What could cause a freeze like that to happen only during the actual event, and how can I prevent or handle it next time?

Rehearsal success does not guarantee live reliability. Use the same laptop, projector, adapters, display resolution, sound system, power connection, and clicker during the full rehearsal. Disable unnecessary power-saving features, keep drivers and Office updated, and consider replacing embedded videos with links to locally tested files. Still, always prepare a PDF and video backup because sometimes the computer simply decides to stop cooperating.
For an important event, keep a backup laptop ready and have the slides and videos available in simpler formats. Export the slides to PDF or images and save the videos as standard MP4 files that can play in a basic media player. Ideally, the audio-visual team should have its own copy and be able to switch sources quickly.
There may not be a single answer after the fact. A brief storage or hardware hiccup, a driver issue, power-management behavior, or a video playback problem could all cause it. Live events follow the law of maximum inconvenience, so the important part is having a recovery plan rather than assuming the software will behave.
Embedded videos are a common source of PowerPoint trouble, even when they work perfectly during testing. Differences in display output, audio hardware, power settings, video codecs, or the presentation file itself can trigger a failure at the worst possible moment. Testing on the exact event setup is more reliable than testing only on your own laptop.
Large presentations can also become unstable over time, especially if lots of video clips have been added. File size and memory usage are worth checking.
Having a second machine with the presentation already loaded, plus a separate copy of the media, makes a huge difference when the primary computer fails.
