PC Won't Boot After New GPU

I'd been having problems a few months ago with my computer - white-screen crashes, no-signal from the monitor, force shut-down not working while attempting to power-off the computer. I couldn't use it at all.

I just recently bought a new graphics card (Zotac GTX 970) to try and resolve it. For the first day it seemed to work - I finally received a signal from my PC and was able to log in, wipe and reinstall graphics drivers, and attempt to play a few games on it. It worked, for about an hour and a half before I would suddenly lose signal and have to restart.

Now, two days later after being away, I've come back to find I can't get any signal yet again from the GPU. The PC turns on - the cooling fans start up, my mobo's LED lights turn on, but I've noticed that the new GPU's fans are not spinning on start-up, while my monitor receives no signal. I have to turn off the PSU in order to force a shutdown. I plugged in the old GPU, and its fans started up - however, I don't really think going back to that one is an option.

What's going on here? Am I having a problem with the PSU, my PCI cables, or my motherboard? Faulty GPU? Or something else? Appreciate any help. Thanks.

My specs:

Processor: AMD FX-8350 CPU (8x 4.00GHz/8MB L3 Cache)
Memory: 16GB [8GBx2] DDR3-1866 ADATA XPG V2
Motherboard: ASUS M5A97 R2.0 -- AMD 970
Power Supply: 750 Watt Enermax LEPA G750-MAS 80 PLUS Gold
Graphics Card: Zotac NVIDIA GeForce GTX 970 - 4GB
OS: Windows 7

And a link to the related issue I was having earlier, if it helps:

First thing I would do is reseat the graphics card and plug back in all PCI cables back into the card.

But if you had previous issues prior to the 970 GTX it strongly suggests that the PSU is faulty.

Do you have a friends power supply to use or a multi-metre to check if the power supply is outputting enough wattage?

EDIT: Also, try resetting your BIOS back to default settings to rule out issues on the software side.
