**Short description of error**
I am experiencing a problem, when i start Blender (2.77a/2.78b/2.78b | from .zip/.msi | from hd or from external hd) the cursor in the cmd line keeps blinking for several minutes before the Blender start-up file shows up. When i try to open a file or (for instance) try to change the tmp folder were renders are being saved it also takes a minute (at minimum) before the file browser opens. Another strange thing is that in the recent file section some file load immediately, but some others don't (also takes a minute or so). Please have a look at the video i screen captured. http://www.filedropper.com/2017-02-2416-55-59-3
I also created a system-info.txt, whats been added to this post.
I already accessed C:\Users\%Name%\AppData\Roaming\Blender Foundation\ Were i moved the complete Blender folder to the desktop. When opening Blender again all my user preferences were indeed gone but the same problems still occur.
