Also, both games use to work with SWITCH before I changed PC (I had Windows 8, now I'm running Windows 7 Professional), which is why I'm sure Magicka works perfectly fine with SWITCH (actually, it works really fine, a lot better than Skyrim. Somehow I improved a lot my FPS without lowering the graphics).
Now I'll update my video driver, but I don't think it will work. Thanks anyway for your help, I'll be waiting for you to find out something more about the quitting message.
