If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.

What are the complete computer specs, including hard drives (how many, what kind, what is on each, and how full)?

And:

Please use the free MediaInfo and post a screenshot the properties of your media in tree view:

If the file is variable frame rate, which although Adobe says it will support, many users are having issues with VFR.

Use Hand brake to convert to constant frame rate:
