No, leave the bios settings as they are.
Ok, I checked the technical specification: https://downloadmirror.intel.com/21240/eng/DZ77RE-75K_TechProdSpec05.pdf
On Page 11, section 1.1.1, table 1 (that is a lot of ones!), under "Graphics" it says this:
Support for PCI Express 3.0 x16 add-in graphics card
Note: PCI Express 3.0 is only supported by 3
rd generation Intel Core processor family processors
You have a 2nd gen processor.
It also says the same under section 18.104.22.168 on page 56 (Note).
So, I suspect the issue is compatibility issue. Too bad - that is a nice graphics card.
Also, while not part of this discussion, your processor is not supported on Windows 10.
You may want to find a 3rd gen processor that is supported on your board and bios, and try it. But, I cannot say that it would make the problem go away.
Here is a list of compatible processors for your board, just in case you are interested: Compatible Processors
Here is a comparison of 3 3rd gen processors that are compatible, plus your 2nd gen processor. ARK | Compare Intel® Products
Again, I cannot say it would work. But, if you can get one of the 3rd gen processors for a good price, it may be worth the effort.
All standard disclaimers apply.

Thank you very much to Al Hill for the information provided on the previous posts.
I just wanted to confirm the information posted previously.
The best option in this case, as it was mentioned before, is to try a BIOS update to the very latest version of the board, if after that the problem remains, then is because the video card is not compatible with the board.
Also, as you can confirm on the following link, the board is not compatible with Windows® 10:
Just to let you know, I looked for a list of tested peripherals for this board, but the information is not available, let me apologize for that.
Since this is a compatibility situation, there is not much that can be done in order to make them work together.
Any questions, please let me know.
