Game returns to desktop during launch

[Winduck]

Hello fellow kerbonauts !

I have a strange problem with my (unmodded) install of KSP. All of a sudden, the game refuses to start and crashes during the launch (every time while loading "fuel line" apparently). I haven't modified anything since the last time I played normally. Twice before that, the game crashed when I tried to load a saved craft in the VAB.

I verified the files in Steam but the bug still occurs.

Any idea please ?

Thank you in advance !

MSI Afterburner and similar programs cause the game to crash.

Thank you for your answer, however I don't have that software installed. 

Just in case, I turned off Aida64. No change. Then I turned off RivaTuner and, oddly, the game stopped crashing on start up. 

I have no explanation since I didn't make any modification, neither to the game, nor to RivaTuner. KSP just suddenly start to crash at launch, for not apparent reason.
