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!

Regards,
Ikw

File / Load Factory Settings
In the User Preferences / System panel you can change the text size

Ctrl -middle mouse and move right-left zoom some interface parts in some windows (Outliner is an exception for some reason e.g.).

Adjust the interface’s DPI.

File > User Preferences > System > DPI

Bump it up a bit.
