I recently tried to add a second GTX 1080 to my system. The first time, the PC booted into Windows without any problems, but the new graphics card wasn't working properly so I decided to shut it down and try again.

The second time I powered on my PC, it wouldn't boot into Windows at all. It normally takes a few seconds but after minutes of waiting, but nothing happened. During this time On this screen tried to enter BIOS and the boot menu, but I couldn't access either. The third time, I removed this new graphics card and powered on my PC exactly in the state it was prior to installation, and it still won't boot to windows and I can't enter BIOS nor the boot menu. Reset the CMOS, same thing. I've had a GTX 1080 work with a GTX 1060 in this same system before flawlessly.

Edit: I was just able to enter BIOS. I reset all settings to the factory default and tried to reboot, but I'm still stuck in the same screen. No warning lights on the motherboard or anything.

TLDR: installed second graphics card, my PC is stuck trying to boot but nothing happens, I can't enter BIOS, so I have no idea what to do.

Please advise.

Windows 10 64 bit
MSI B350 Tomahawk
AMD R7 1700
GTX 1080
EVGA Supernova G2 750 watt PSU
Samsung 850 pro SSD

Other things to look at... What is the occupancy of your boot drive vs formatted capacity? Over 80%?

Have been able to force Windows 10 to "self-repair"? I normally get it to do that by pulling the plug once it boots, it sets a state where the OS loader sees an issue and gives you the opportunity to let Windows try to fix itself or lets you load a restore point.

Everything is where it's supposed to be. I booted into Windows once with these two graphics cards, turned off the PC, and that's when the problems began. I didn't even touch anything.

Well I guess I'm left with a broken PC because I've already tried every solution to this problem online. Unlugged all USB devices, reinserted components, unplugging the hard drives, clearing the CMOS, nothing works.

I was considering doing this. Right now I'm running memtest just in case. After that I'll try to boot from USB, thanks for the suggestion.

On the splash screen there is a spinning circle indicating that it's loading, so the graphics card seems to be working. Problem is, this circle is spinning indefinitely and I can't get past the splash screen.

I booted into Hiren's because I don't have any flash drives large enough to fit Gandalf's on. I have the following options available to me: http://imgur.com/a/eek6e

What should I do next?

Edit: I ended up trying to boot into "mini windows xp" but that resulted in an error. http://imgur.com/a/bKjm3
I decided to follow the steps suggested on that screen. Restarted, tried booting into mini windows xp, same thing happens. Checking for adequate disk space? Not sure how this means, but the flash drive being used here is pretty small, 2GB. Should this be enough for the diagnostic? Next: changing video adapters? I already know that at least my first GTX 1080 worked, so there shouldn't be a problem there. As for BIOS updates, I already have the latest BIOS on the motherboard. Memory caching and shadowing: couldn't find these on my motherboard. Maybe they're not available. And then I'm not able to boot into safe mode because pressing F8 does nothing. I'm completely stumped.

Well, it does but I'm using an R7 series CPU that doesn't have integrated graphics. Unfortunately I don't have any other GPU's on hand for troubleshooting. However, I believe that this may be an issue with Windows 10 rather than hardware. It looks like the PC's actually getting stuck on the part where it loads the operating system (I turned off the full screen logo display option in BIOS and it hangs on the part where there's a windows logo and dotted loading circle, just like the one here: https://www.drivereasy.com/knowledge/windows-10-freezes-startup-solved/).

Now I'm onto something. I think that either a graphics driver completely broke that Windows installation, or Windows just broke itself somehow. It could also be a hardware problem with the SSD (maybe it got too warm?). What I do know is that the motherboard, RAM, and connectors are all fine.

I figured that this is the case because after swapping my SSD for another hard drive and installing Windows on it, the computer was able to boot into Windows just fine. First I booted with one graphics card, then with two, then I installed the graphics drivers, and voila, both are recognized by windows.

I think that my best course of action now is to clone my SSD and perform a clean installation of Windows to figure out whether it's the OS or SSD that's causing the problem, but I'm still open to other suggestions.
