I sorry but I have no further suggestions. This is a bit too technical for me and I don't know what else could be causing it.
Maybe someone else can help you better.
Thanks anyway
one thing that can cause this is you might have to manually input your screen resolutions right click your screen make a note of the screen resolution go to your steam right click the game-properties-set launch options when the box appears type in your screen resolutions for example if your resoultion is 1280x101024 type in -w1280 (space)-h1240
Tried this solution, no change.
