EDIT:
Solved at post #7.

I'm trying to flash a different BIOS on my 3080, but I can't get to Windows when it's connected to the computer while I'm using the iGPU.
My computer keeps turning off and restarting itself with BIOS set to default.

* I tried removing overclocks and it doesn't work.
* Pulling out the card and using iGPU only works fine.
* The 3080 works fine.

This issue seems to be present when the primary adapter in BIOS is set to iGPU. Correct me if I'm wrong but that's the only way to start the computer with the iGPU?

Set the bios to use the iGPU as your primary output. If you only have the iGPU connected and no GPU installed it should default to that on auto. Some boards will boot with both enabled (w/ display connected to mobo) and it set to auto, others won't.

Depending on the board, the default behavior is to make the dGPU the primary one. If your primary adapter is set to iGPU, you should have display on the iGPU when a dGPU is installed.

Maybe a new bios available?

Also I think he's flashing because he's not getting a high enough hash rate, might be a bad idea.

Well, yes, I wouldn't recommend doing that, but it doesn't change the fact that he should be able to use both the iGPU/dGPU at the same time regardless of the reason he wants to flash the card.

EVGA does flashes on the primary adapter from their software. I've flashed old Polaris cards that were the primary adapter for mining purposes and Navi for non-mining purposes. My Nvidia 3090FE flashed as the primary adapter to enable Rebar using their software. The only time you needed to use a secondary adapter when flashing was to fix a bad flash.

Right, I recently used precision to flash my 3080. I've also flashed nvidia and amd in the past but generally shy away from flashing another card's bios onto my card unless there's ample evidence it will cause no issues. I believe that's warranty voiding as well.

I got this solved.

I have been setting the BIOS to iGPU but I should have just let it stay at PEG or whatever it's called and just activated "IDG multi-monitor" option.
That fixed it and I was able to get into Windows.

Flashing the BIOS also worked. Fixed both my hashing issues as well as the card boosting over 100mhz more in games with the new BIOS.
