My Gigabyte mobo acting up

[YellowSwap]

My motherboard won't work with mixed graphic cards, if you add AMD GPU with Nvidia GPU the motherboard will start behaving abnormalities, boots and shut downs, boot and reboots, long time to boot on, all this stuffs but if I use 1-6 sets of the same graphic cards it will work perfectly, I've never seen anything like it.

What Gigabyte motherboard do you have ?
A little bit more Information would be for sure helpfull to us as we cant guess what Version of motherboard you have !
There are 100 motherboards from Gigabyte if not more    .
What OS you are using  , maybe or i guess if we get the Infos we will find the possible problem for .

Not the mobo as much as software. 

Do you run windows to mine and do nicehash?

I have some new upgraded rtx 2060 12gb evga and they only run well with each other.

I can not put the on a mobo with any other cards and get results.

And I have a dozen mobos to fuck with not just a gigabyte.

The bios on the evga card is twisted.

I suspect that this motherboard have Crossfire enabled ( two x16 slots ) that supports SLI and Crossfire, there could be an interference issue between drivers if you connect the AMD in a x16 slot and another Nvidia in the second x16 slot, this have happened to me once but knowing which type of motherboard you have would help more.

Mine works fine, I have a combined AMD and Nvdia GPUS mining together. I've put my Nvidia first and boot it, after that I shut it down and put the cards one by one, boot and reboot. Try it first with 2 cards, a single Nvdia and a single AMD.

Install Nvidia graphics cards first, then AMD graphics cards. If the BIOS firmware does not help, then select a working configuration with the maximum number of video cards.What motherboard and what graphics cards do you have?

I think you don't get what OP is saying, the Motherboard isn't even booting up once it detects that AMD and Nvidia is installed on the Motherboard, Even if both AMD driver and Nvidia driver are already installed in the Harddisk it won't boot up anyway, I can't think of anything else that a BIOS problem.
