I just bought a 2070 super yesterday and installed it into my computer and when I go to press the power button on my case it doesn't post but the weird thing is if I press the reset button it will post. I then went and downloaded the driver from nvidias website and restarted the computer and it made it to the desktop. I shutdown the computer and press the power button on the case and again it does the same thing and gives me a blank screen. I then switch back to my previous gtx 970 and it went back to normal and posts every time I press the power button. My question is this happening because my current set up is around 10 years old? I know the minimum required system memory is 8gb while I only have 6. I did purchase other components to build a new pc so I just wanted to test this video card to make sure it works and I don't want to have to return it if the problem is my pc and not the card itself.

Just an update if I use the hdmi port instead of the displayport it works 100% of the time from a cold boot. If I cold boot from displayport nothing posts unless I press the reset button on the computer case. This doesn't make any sense since I was using displayport on my gtx 970 previously and worked no problem. I don't think there are any recent bios updates for my motherboard as its 10+ years old
 
Edit: last bios update was in 2011 which I'm currently on. 
I've also ordered the following components below.
 
Core i7 9700K
Asus ROG Strix Z390-E motherboard
Gskill Trident RGB 8x8 16gb ram
Seasonic Prime Px 850w power supply
Corsair x570 case
Noctua NH-d15 Cromax cpu cooler

Your system may not like fast startup, which hangs waiting for the cached image to boot. but you shouldn't need a script to disable it:

Try the following:

In Control Panel ->  -> Power Options -> Choose what the power buttons do, then under the Shutdown settings section, if the box is checked then Unchek  the "Turn on fast startup (recommended)".

My previous gtx 970 used displayport and worked just fine. I just don't get why its all of a sudden happening now with the rtx 2070 super using the same output. 
I'll see how it goes once my parts come in on tuesday.

Thank you for all the help to everyone who posted in this thread. I have ordered a vesa dp8k certified displayport cable to go along with mentioned components coming on tuesday below and will give an update.

Ah yes...good old X58. The 90% solution for this is to do a cold BIOS reset. First off make sure you have all your settings saved in some manner. Shut down the system and remove power. Take out the BIOS battery, press the CMOS reset button for 30 seconds. Leave the battery out for 15 minutes. This should ensure any residual settings are erased from the BIOS.  Sometimes what happens is the BIOS does not correctly detect the new GPU and uses the old ESCD data  in the BIOS to initialize the GPU. I would also suggest, if you have not, given the age of the board, replacing the CMOS battery. Reinstall the battery with the new GPU installed and set up your system as required. Also, make sure the 3GB low gap is set.

I'm really thinking its the age of my pc as it doesn't meet the minimum system memory requirements of 8 gb while I only have 6gb is most likely the culprit. It could also be the bios like you previously stated and must not be reading the video card correctly from a cold boot and only sees it the 2nd time when I press the reset button. The 2070 super will be going into the new rig so I'm not too concerned if the problem lies in my current setup. 

 
I would also suggest you go for 32GB of memory. It's fairly cheap right now and don't go slower than 3200 C16.

Good to hear the new build is firing on all cylinders!

Enjoy it!

excellent, enjoy the new set-up !!!

Had same issue with few cards myself. Never figured it out
