I recently move my pc components over to a new case. After that everything was fine until I started playing games such as max payne 3 and dayz, Horizontal lines - partly transparent flashed on the screen. I did a little research and found that they were known as tears? They said that the problem was that the monitor refresh rate wasn't syncing with the game's fps rate. That enabling v sync will solve the problem. However it didn't. The thing is that I had no problem with tears before and nothings changed except that I moved components to a new case. What could be the problem and how can I solve it?
