Every once and a while, in the middle of the game, the game will freeze/lock up. Then crash and become 'unresponsive'. But, i'll have to turn off my computer manually then because when it comes back, my entire computer becomes screwed up. The colors are inverted, and i can only see about 1/4th of the screen, it zooms in almost.
The game used to run fine with no problems a while ago, but now this happens. I've tried uninstalling it and re-installing it through steam, it seemed to work, but it happened again.
