Test if the videos play properly in the GraphStudioNext tool. They should use LAV Video decoder.

Do those files perhaps contain 10-bit H.264 video? The Media Foundation codecs that WMP uses do not support that.

Try this:
Codec Tweak Tool > Media Foundation > Disable for AVI and MP4

It might be a problem with the video renderer.

1) First try updating your graphics driver.
2) Disable hardware acceleration in the video decoder, in case you have enabled that.
3) Try a different video renderer in MPC-HC.
Options > Playback > Output > DirectShow video > Video Mixing Renderer 7 (windowed)

Do you perhaps have a Sony Vaio computer with an AMD Radeon graphics chip? That has a known compatibility problem with video playback on Windows 8.1 according to Sony website and various forums.

A possible solution that I found is to install the Windows 7 driver for the graphics card, using Windows 7 compatibility mode (right-click on driver installer > properties > compatibility).
