GTX 960 not recognized by Windows 8.1 or Nvidia Driver Installer (GPU not showing up in device manager)

[keyskull]

I bought a gtx 960 that I am using to upgrade my Dell Inspiron 660 (normal, not slim). However the card is not showing up at all in device manager and no signal via vga (card came with adapter) or hdmi. (yes i plugged in the vga/hdmi into the graphics card, no signal)

When I tried to install the driver I received a "no compatible hardware found" error.

There is no setting in BIOS to disable the on-board graphics or change to the new card.

The GPU is being powered by a separate PSU as my PC only had 300w
The card requires an 8 pin pci-e cord which is plugged into the card and secondary PSU.

The card is brand new but the computer is a few years old.

I am certain none of the parts are faulty. However, I don't really have a way of checking the card in a different PC.

Specs:
MOBO Model: 084J0R
BIOS: A11 (updated)
CPU: Intel i5 3330
Operating system: Windows 8.1 (updated)
Current Graphics: Intel Integrated
Primary psu: the original PC PSU (300w)
Secondary PSU: Corsair RM 550w

For HDMI i am connecting to my TV which is a Magnavox (no idea on model number)
For VGA my monitor is an HP monitor (20 wm, Product number D2A13A)

Any help would be appreciated.
