Hello SeventhSin,
Please, you're just chasing your tail here...
Now the truth is coming to light.... You are in fact testing on three different machines with various types of hardware, but as far as I can tell we don't know which architecture you're using (eg: TC -10 x86 or Tinycorepure64)?
NVIDIA GeForce GT 430
NVIDIA GeForce GT 740
NVIDIA GeForce GTX 970M
These are all fairly recent Nvidia Video cards which are not supported by either nouveau or nv drivers, these drivers are far too old, forget them.
However, In TC-10 these cards should be supported by the generic Xvesa (in TC-10 x86) and Xorg-7.7 (in TC-10 x86_64, I mean corepure64)
Additionally at least the GeForce GT 740 and GeForce GTX 970M have proprietary Nvidia driver support in TC-9 x86 and corepure64, am not sure about the 430 model
For TC-10 x86
My Geforce GTX 1060 video card at native resolution (and likely yours too) is supported by Xvesa extension
this is my onboot.lst (with personal extensions removed) which supports my Geforce GTX 1060 graphics card (without on chip i915 graphics)

For TC-10 x86_64 (tinycorepure64)
I currently use Xorg-7.7 which supports my Geforce GTX 1060 graphics card (without on chip i915 graphics) using this onboot.lst (with personal extensions removed)
