Mass Effect 3 won't start without any error message given

Whenever I try to start up ME3 Origin just shows this little synchronisation window and then nothing happens. The MassEffect3.exe is running for a few seconds then closes down without any message. I tried most of the solutions already brought up here like running as administrator, using Origin's repar function, reinstalling Origin and the game itself, running it in offline mode etc but nothing seems to work. Installing and older version of the graphics driver didn't work as well.
