Help with GTX970

This begs the question Shane mate is the TV ok?? and even more obvious - sorry but have to ask have you got a dedicated AV channel picked out on the TV?

I would suggest reseating the GPU too and perhaps even this
SLOT CLEANING
Now as for the slots to clean them use a strip of old credit card about 1/2 inch wide nip the corners off one end - preferably round them offhold a piece of thin lint free cloth over the end dab on some form of alcohol - iso propyl alcohol (what we swab the skin with before an injection) is good and GENTLY swipe along the slots.
This can also be done for the GPU slot/s and do not forget to clean the contacts on the cards / sticks either.
It is an idea to clean the contacts on the sticks / cards while you are at it but be VERY gentle when doing this.

The next thing to look at is this
UsingHW Info PSU

Download HW Info and pick the right bit version - HWiNFO, HWiNFO32/64 - Download -(copyand paste this site into the search bar) If you do not need the runninginformation in the smaller right hand panel close it. In the left hand windowclick on the + for the individual device groupings and they will open out tothe various components.

Go on opening out further until you get to the device itself. click on it andit will highlight. In the right hand window there will be a very detaileddescription of that device as in brand, speeds model number etc etc These arevery detailed and are just what is needed for searching for drivers etc.

To getthe PSU volts you need to select the Sensor button circled in yellow in the picfor PSU testing do the same and scroll down the readout as in my pic to whereit has Nuvoton = yours might be a different section name / title. Post back apic of that please.

If you want a more definitive test see this https://www.sevenforums.com/tutorials/301799-psu-test-dc-output-voltage.html butlease only use a digital multimeter and not an analogue as they injecttypically 9v into a circuit to test and into a 3.3v or 5v rail - not a good idea!!see the partial pic of the correct sort of meter in that tutorial. details ifyou scroll down that listing.

Now a good reference article is this
Voltage Rails - Power Supply 101: A Reference Of Specifications it will explain in detail what the voltages are and functions of the PSU/
Could be something as simple as lack of power to the GPU or board.

Very odd and I would hazard a guess at the old card being faulty as I do not know of any cards that incompatible with a PSU because the PSU only delivers volts and current to all components and cannot be any different as they are governed by laws of physics.
But at least it is going:)

Hmm I would curious as to what happened if I shoved the old card into another machine and tried it but that's just me:)
