Miniature interfase

Hi, I´m running Windows 8.1 and for some reason all options on the interface appear in miniature, I can barely read the text. Is there some option to scale the interface to appear at a normal size? I´ve tried uninstalling Blender and installing it back the with no results. Is this related to windows? or another feature on my computer?

Please help! I really appreciate your help to help me figure this out!
