Nvidia control panel hangs when in surround mode

Edit: Resolved. Random symlink on my system was causing nvidia driver to install parts of itself across both my primary and secondary hard drives...

So I just upgraded to two GTX770 4gb in SLI and I've run into a very strange problem... The nvidia control panel hangs when in surround mode.

Here's where it get strange:

• Both cards work individually
• Both cards work fine in SLI (Maximize 3D Performance)
• Both cards work fine in Surround (ie. games play fine, no video issues)

It is only the control panel that locks up, and only when I'm spanning my three monitors with surround. Nothing else in my system is effected. No performance issues (yes even when in surround).

It seems to only hang when entering the following sections of the control panel: "Configure SLI, Surround, PhysX" and "Adjust image settings with preview"

It is also worth noting that the Ctrl+Alt+S shortcut to swap between the two also hangs just like the control panel.

Things I've done/checked:

• Clean driver install (both with and without HD audio)
• Voltage on +12v rail (12.193v +/- 0.001v)
• Refresh rates on monitors are all 60hz
• Various positions of monitors on cards (primary vs secondary card output, etc)
• Physically swapped cards around
• Physically relocated SLI bridge to other fingers

edit:

• Driver roll back, no change
• Motherboard BIOS update, no change

Things I've not yet tried:

• Different SLI bridge (have one coming tomorrow)

Has anyone seen/run into this issue before? I've been doing this kind of thing for near a decade (4+ years of it as professional IT support), and have never seen anything like it...
