Solutions to Fix Video Playing in Slow Motion on Windows

A while back, I wanted to play an HD video on my Windows PC, but I kept encountering a peculiar playback error. Whenever I would load the video, it would play in slow motion instead (even when the playback settings are set to default).

This made me realize that a lot of people might encounter a similar situation due to any application, video, or system-related issue. That’s why, I have come up with this complete troubleshooting guide to fix videos playing in slow motion in every possible way.

Error 1: Your System’s RAM is Insufficient

One of the most common reasons for videos playing in slow motion could be related to insufficient RAM in our system that can affect its overall processing.

Fix: Update your System’s RAM

The easiest way to fix this issue is by updating your computer’s RAM. You can either do it yourself by disassembling your syastem or can get in touch with a professional. While it might cost a bit to upgrade your system’s RAM, it would be a permanent solution and will improve its processing too.


Please note before you check your computer’s RAM, make sure you check its configuration by visiting its System Settings. Ideally, if your PC is running on 4 or 8 GB RAM, then it won’t need an upgrade and you can apply other solutions instead.

Error 2: Too Many Applications and Tasks Running in the Background

If too many applications are opened in the background, then it can also make the processing of your system slower and affect the playback of videos.

Fix: Close Unwanted Applications from Running

If your videos are playing in slow motion, then you can simply close any unwanted application or program that is running in the background. Windows users can simply press the Ctrl + Alt + Del keys at the same time to get the task manager window. Here, you can just select any application that you want to close and click on the “End Task” button.
