Most likely cause is the PSU is not powerful enough for that card so there's not enough juice to boot the system until the card is removed.

PSU wattage is not the only thing that matters, there is also the amps on the 12v rail to consider, if amps not high enough for the card the system won't work.

For a GTX 970 your PSU needs to be at least 550W and capable of supplying 30A on the 12v rail.

Also have you tried the other PCIe slots?

"Most likely cause is the PSU is not powerful enough"

That would be my guess as well.

"your PSU needs to be at least 550W and capable of supplying 30A on the 12v rail"

To expand on that a little, the PSU should also be a reputable brand name, 80 Plus efficiency certified, support active PFC, & have a decent warranty (2 yrs or more).

Please note that this is from personal experience:::
I have a Z97 motherboard (Gigabyte) that would not recognize the GTX750Ti graphics card initially. I tried many things and it would only fully boot when the graphics card was not installed. Since I have a newer i5-4690K and to get full overclock support they recommended the F7 BIOS update (came with F4), I updated the BIOS while I thought about what I might have missed (using onboard video). Of course since I am systematic, and since I made a major change, I retried the video card. Guess what???? It worked perfectly.
I believe that these Z97 motherboards were rushed out a bit fast and the original BIOS' were not fully proven in all configurations. The Devil's Canyon that I have came out a couple of months after the motherboard was released and it was supposed to support the series but it turned out that the BIOS needed updating to support it. Like the GTX750TI I have, your GTX970 I believe was also released after the motherboard was shipped so it is very possible that all you need to do is run the onboard video (or an older video card) long enough to update the BIOS to the newest one and try it again.
Of course updating BIOS' is always a risk so appropriate cautions need to be taken (I run a UPS which protects it from possible power problems).
To me it is worth the risk if you are careful since there is a reasonable possibility that it will fix your problem.

You have to be a little bit crazy to keep you from going insane.

There are PCIe configuration options in the BIOS for the Z97-a however I would certainly research them thoroughly. Any incorrect configurations would likely blue screen your computer. If that happens there is always the option of loading optimised defaults to correct it though.

To determine if there is a BIOS update for your motherboard you will first need to determine which version it is currently running and if there is an update for it.

Here is a discussion in the ASUS forums:

As always when updating the BIOS read all instructions very carefully before you proceed. Any mistake could be catastrophic.

Edit: here is an ASUS BIOS update guide on YouTube which should be very similar if not the same as your update method:

Remember to heed all warnings and if there is any doubt with what you are doing come back and ask for advice.
