Your computer is somewhat underpowred for video editing, and OpenShot is no exception. You don't mention how much RAM you have in your computer and what type of a hard drive and how much free space you have.

but try these adjustments and see if this helps:

1. Free up as much disk space as possible.
2. Ensure your Windows operatins system updates and hardware drivers are up to day.
3. Make your "Video Preview' a bit smaller in size.
4. Make the following Cache adjustements in Edit | Preferences | Cache tab:

Let us know if this helped.
