When I go to /usr/local/cuda/samples/1_Utilities/deviceQuery
and execute
moose@pc09 /usr/local/cuda/samples/1_Utilities/deviceQuery $ sudo make clean
rm -f deviceQuery deviceQuery.o
rm -rf ../../bin/x86_64/linux/release/deviceQuery

moose@pc09 /usr/local/cuda/samples/1_Utilities/deviceQuery $ ./deviceQuery
I keep getting
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35 -> CUDA driver version is insufficient for CUDA runtime version Result = FAIL
I have no idea how to fix it.

The solution is to properly clean out the old driver. The exact methodology will depend on how you installed the 410.79 driver as well as how you isntalled any previous drivers or install attempts. Another possible source of error is if you installed the 410.79 driver from some non-NVIDIA resource, such as PPA.
Update your NVIDIA driver. At the moment you have the driver which only supports CUDA 6 or lower, and you are trying to use the CUDA 7.0 toolkit with it.
