Hi guys,
I'm having trouble setting up a PC with both a GTX 1080 and an RTX 3090 Ti. I've tried various solutions but the 1080 boots with a code error 43 in Device Manager, while the 3090 Ti works fine with code 45 but doesn't function at all. After disabling its enable, it's still working. The monitor shows nothing. I've tested different drivers, reinstalled Windows, checked the PSU, motherboard connections, and more. Could anyone suggest a solution?
I'm open to any ideas you might have.

It's challenging to utilize two distinct Gen cards from the same maker. What is the reason behind this approach?

Because I have multiple monitors and a 1080p display, it might seem tricky, but some users manage it easily by simply connecting the cards.

How do you transmit the power-on signal to the second PSU?

Wire the two pins of the 24-pin connector. I just power on this PSU before the other and then press the power button.
I understand this GPU is designed for more than one monitor, but for some reasons I might face a situation with five monitors, which this GPU can't manage. Even though it seems useless, I really want to be able to use the 1080p resolution.

I think the drivers are causing a lot of issues because different hardware versions are competing for dominance, and then they fail due to conflicts. You might try removing all Nvidia drivers with DDU, install the 3090Ti along with its drivers, restart and check if it works. Then try installing the 1080 without any drivers and see if Windows installs them automatically.

It's what I'm attempting at the moment. The main issue is that the 3090ti isn't functioning properly. Once the system starts up in Windows, it shows for a short time before stopping after some delay or when I press the keyboard keys (though I'm not sure about that). The drivers are set up specifically for the 3090.
