Changing your DPI settings on Windows can cause all kinds of strange issues. I had a problem a few years back where my Windows 7 gaming theatre PC thing I had set up and connected to my 1080p TV wouldn't work quite right; specifically Star Wars: The Old Republic wouldn't launch, and would crash on loading. I couldn't figure out what the problem was, and googling was no help until I stumbled across the dumbest advice I'd ever seen: change the text scaling. Once I set it back to 100%, the game loaded fine. Frustrating, because at 100% I couldn't read any of the other text, which meant that if I wanted to play the game I basically had to navigate by icon and give up on reading dialogue boxes unless I wanted to sit on my coffee table instead of my couch.
