VLC crashes / freezes / BSODs my computer
VLC doesn't do that. Normal apps shouldn't be able to cause issues like these to operating systems.
Culprit is usually bad device driver (for example display adapter driver, soundcard driver, chipset driver, network adapter driver etc.) or broken hardware.
If you still cannot trace out the problem then try resetting VLC Settings by the following procedure:
If you can start VLC, go to Tools -> Preferences and then press Reset Preferences. Save to reset and save VLC settings.
Remember to restart VLC after that to make sure changes are enabled.
If you can't start VLC, go to %appdata% folder and delete vlc folder from there.
