GTX 1080 not playing nice with my old mobo (Solved)

So I just purchased an EVGA GTX 1080 FE the other day, put it in my Asus P8P67, and turned my computer on. The Asus logo appears, I get the usual POST succeeded beep, but instead of starting to boot into Windows it just hangs and gives me a short, quiet beep about once a minute, which according to the manual means "VGA detected, Quick boot set to disabled, No keyboard detected" which doesn't really make sense. And I'm sure I didn't break anything because I swapped back to my old GPU and Windows came right back to life (and yes, the keyboard works), then swapped to the GTX 1080 again and got a frozen UEFI and beeping again.

Now Asus is basically ignoring me (I'd heard their customer service has gone down the drain over the years, though given that this board is years out of warranty I wouldn't be particularly surprised regardless) and EVGA is saying that seeing as I already have the latest BIOS installed, there's nothing they can think of or help with (which does surprise and disappoint me, given their good reputation and the fact that this is a brand new card).

Before I take it back to the store (and possibly take the 15% restocking fee hit), I figure I might as well check if anyone online might have any ideas as to what's going on. Any help is appreciated!

Is your system booting in straight UEFI mode, or is it in legacy/compatibility mode. It's in the blue x16 slot, right? The black one runs at x4.

I do have to mention it seems like a bit of a waste to put a 1080 in a system of that age.

Yes, it's in the blue slot, and neither UEFI mode or compatibility mode will boot - actually, I can't even get into the BIOS when the 1080 is installed as it seems the system is frozen by that point so boot mode differences may be moot.

Power supply?

(Well you could determine whether compatibility mode is enabled with the old gpu installed.) I assume you have installed the latest bios.Though it may be a bother, before I returned it as incompatible, I would run the 1080 in another system. If the card is defective, there should be no re stocking but a retail replacement of a defective product.

I've already tested it in both compatibility mode and UEFI mode. Neither works.

I briefly thought about asking around to see if anyone I know still has a gaming desktop, but then I realized that at the end of the day, regardless of whether it's actually dead or simply incompatible the card does not work with my PC, and I'm sure the store will be doing their own testing when I bring it back anyway.

You could try a BIOS reset with the 1080 in the slot. Is the power connector for the 1080 going in tightly?

Ding ding ding we have a winner!

I can't believe I never thought about this, but doing a BIOS reset while the was 1080 installed miraculously fixed the problem.

Thanks, XavierMace, VirtualLarry and deustroop :) And double thanks, Ketchup :D You guys are way better than the "technical support" staff at Asus's and EVGA's call centers :mad:
