21 ram dedicated to adobe premiere.

How much does that leave for the system to use?

I would suggest allowing more RAM for the system, maybe 16GB Premiere and 8 GB system, although that is not a solution your main problem.

It seems that your videos are recorded with a cell phone in VBR (Variable Bit Rate). Make a test by right-clicking the clip in the Project / Modify / Interpret Footage panel ... In this panel, set the clip to CBR (Constant Bit Rate), for example at 30 fps.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

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

If that doesn't work, try creating a new project and import the old one into it.

Many users are having issues with VFR. If the file is variable frame rate, use Hand brake to convert to constant frame rate:
