Full screen kills the game dead.

Started the game, then switched to full-screen, and it started dying in agony. The screen flickers constantly between a blank screen and fleeting glimpses of my desktop, so I don't even have enough time to kill the process. I have to restart to be able to do anything on the computer. It looks like it's locked in a vicious struggle for control of the resolution with windows, 'cause I can see the cursor changing sizes every half a second or so- but it never settles.
That's on Windows 8.1 with Intel integrated graphics.
I've uninstalled and reinstalled three times, also ran a registrly cleaner, but every time I start the game it tries to go to full screen and keeps failing like that.
I'm looking for an .ini file or maybe a registry key I might have overlooked. It must be storing that fullscreen=1 (or sth) value somewhere.
Haven't played the game almost at all and spent way too much time trying to find the setting. A bit sad now
