How to fix display problem in windows 8?

I got a Lenovo laptop (Y510) recently and installed windows 8 pro on it. I have a problem in display in most of programs. In Microsoft Office programs ribbon icons are big and are not transparent. In Abaqus the bottom part of some command windows are out of screen (They exist there, like OK and Cancel buttons, but they can't be seen in screen) and ribbon icons are bigger than usual (I have another laptop with windows 7 and can see this ions properly there). I spent the last days searching to fix this problem but it still did not solved. The recommended resolution is 1366x768 and the laptop screen is HD.
