How do I restore my User Preferences>System panel? I went to User Preferences > System panel to change my viewport anti-aliasing settings, but all I see is this column:



I'm using Blender 2.78c, on Windows 10.

Here is what I'm expecting to see, screen-capped from an older version that I have installed (2.77a):



I've tried uninstalling/reinstalling Blender and updating my graphic card drivers (Geforce GTX 980).
I've also tried Loading Factory Settings without any luck.

Edit: I just opened the info panel up and I'm seeing this error, it seems like it might be relevant:

"
Traceback (most recent call last):
  File "C:\Program Files\Blender Foundation\Blender\2.78\scripts\startup\bl_ui\space_userpref.py", line 433, in draw
    userpref.addons['cycles'].preferences.draw_impl(col, context)
AttributeError: 'NoneType' object has no attribute 'draw_impl'

location: :-1
"

It seems switching to Cycles and making the Viewport Draw Mode as 'Rendered' causes Blender to crash.

Any help is greatly appreciated!
I was able to solve this by disabling the Cycles Render Engine in the Add-ons panel, this let me restore the System panel to how it should look.  



As for getting Cycles to work again now, I'll ask another question...
