Hey guys, so I finally scrapped enough cash to put together a new PC (mostly for art school but also for gaming on the side and mining when not in use). However on starting cgminer with various settings (from nothing to complex sets) I get the error message seen in the subject.
"cgminer -n" spits out

I saw a recommendation to uninstall nVidia's PhysX drivers, however no luck. If anyone has any ideas on what to try I would appreciate it (as I won't be in possession of a 40 GH/sec ASIC unit any time too soon

). Let me know if more information on hardware would help (I'd also be willing to switch programs, however cgminer has severed me very well in the past and I like those involved in the project). Grazie!
Edit: Not the optimal solution (as the issue was not solved) but changing to BFGMiner worked.
