GA-Z77-D3H (rev. 1.0) and Nvidia Geforce GTX 1070 black screen

[Dreadnought808]

Greetings GIGABYTE!


For many years, my home-built gaming computer with the GA-Z77-D3H motherboard has been performing admirably.  Alas, last week my graphics card (Geforce 560 TI, beast of a card, still ran everything perfectly) gave up on me (or so I assume) and started showing a bunch of short, horizontal artifacts covering the screen.

I verified that everything was still fine with the old card removed- the system was working with the internal graphics, and spoiled myself with the new Geforce 1070.
After days of blood sweat and tears, I can admit- it's not working.

Power supply is a 750W so should not be the cause of the problem.  I obviously plug the monitor cable into the graphics card when installed. I've upgraded my BIOS from F8 to the latest F22. I've fully cleared my PC of any old drivers, registry leftovers and Nvidia folders.  I've tried inserting the card when no drivers are present, and when I've pre-installed the Nvidia drivers. I've tried a few different BIOS settings (standard settings, turning internal graphics off and such) It all leads to the same result: black screen.  System is Windows 10 Home (upgraded from 7)


The monitor does get recognised, and I hear the computer booting properly and making it to windows, indicated by the startup sounds.  In fact, if I let the whole process run, and then remove the card to reboot on internal graphics, I find it's actually installed the card as should be expected.  I don't even see the BIOS screen at startup, making any changes and additional attempts very time consuming, involving removing the card.

I have no second system to verify if the graphics card (both the old and the new) is in fact functioning.  My windows device manager is clean as a whistle- no conflicts or problems.  All drivers have been updated- Driver Booster tells me all is well.

I'm starting to run out of ideas.  I'm suspecting a certain combination of BIOS settings is required for this beast of a card to work.  Another possibility would be a defective graphics card (it's brand new and quite expensive) or a defective motherboard.   Any help is deeply appreciated!  My thanks in advance.

If you have no way to test things it could the be the slot too.

Hey guys,
Isn't Z68 / Z77 about the time we started seeing newer cards with BIOS' that weren't always compatible with some boards? Dreadnought808..  what CPU do you have Sandy or Ivy?

I have a 560Ti running on a Z77 Asus board.     Still going strong, but the system has always been a little quirky.     I had to remove Lucidlogix VIRTU MVP after upgrading it to 10. 

I recall EVGA putting out BIOS for many of their cards that required a flash to run in conjunction with older boards. 

F22 (wise choice) Thats as far as I would have gone as well.  Dreadnought808, you really need to test the card elsewhere to confirm its ok, and/or put another card in your boards PCIe slot to confirm all is well there too.  PITA sorry.  If your BIOS has option for different GPU Gen options and is currently set to Auto, try others as we've seen this may the difference previously.

Hi, I registered just to update this one. I was in the same boat last night, F22 BIOS and no signal with my new 1070 card. In the end, I thought what the hell and updated to the beta F23 BIOS, as I'd run out of options. Turns out this does the trick.

So if you're experiencing issues with 10xx series cards and this motherboard, go for F23 beta. Load optimised defaults and you should be in business.
