PC won't boot whatsoever when graphics card is installed (long and highly detailed post below)

I am going to highlight exactly what I think caused this, and every solution I have tried, to be as absolutely clear as possible.

I am using a GTX 1070 (Gigabyte) graphics card. I have been for several months. This is installed on an MSI Z87-G45 motherboard, with an i7-4770k. I have 8gb of Corsair XMS3 RAM. I have 3 monitors. One is a DVI monitor, plugged into the 1070, the other is an HDMI, plugged into the 1070. I also have a graphics tablet monitor, which was plugged in via HDMI to the motherboard, not the 1070, due to me not having a displayport adapter at the time (the 1070 only has one HDMI port). This setup worked fine, as my motherboard had a feature that allowed screens to be run from both the 1070 and the motherboard seamlessly and simultaneously.

However, today, I decided to update my graphics drivers. This are the latest drivers as of the time of writing. Partway through the installation, the screens went black - a standard short term effect when installing graphics drivers. However, they stayed black. I left them for about 20 minutes or more. Eventually, I gave up, and force shut down my PC with the power button.

Since then, the computer will not work properly with the 1070 installed. When completely removed and unplugged, and one monitor plugged into the motherboard directly, the computer boots (I'm typing with it now).

However, when I plug the graphics card in, a series of events happen depending on which order I do things:

With the 1070 plugged into the PCI Express port and its power connectors, with the HDMI to the monitor plugged into it, it gets past my BIOS screen (slightly slower than I would expect), before loading the Windows 10 loading screen. Either the Windows logo disappears, leaving just my cursor and the loading dots, or the screen is completely blank, or completely blank with only a cursor. I have tried typing in my password, pressing CTRL+ALT+DELETE, and moving the mouse (the cursor does move). I can't get past this stage.

With the 1070 plugged in to the PCI express port and its power connectors, with the HDMI plugged into the motherboard, not the card, it doesn't even show my BIOS screen. Just blank. This happens even if the card is placed into the PCI express port without its power connectors.

When I place the 1070 into a different PCI Express port, it boots to an extremely low resolution login page, before going to a black screen. Nothing interacts with this screen, and when I shut down it just reverts (seemingly permanently) to the stages above.

When I try placing a different graphics card (an old 770 in this case that was working fine) the same happens - low resolution login screen, black screen, stages above.

I have tried resetting the CMOS on my motherboard by removing the button cell battery with the PC unplugged, pressing the power button (PC is still unplugged), placing the button cell back in after a few minutes, restarting PC with it plugged in. I know this worked as the date and time in the BIOS had reset to factory settings (00:00:00).

When in my PC without the GPU installed, I've uninstalled Geforce experience and all drivers I could find. Notably, I couldn't find my actual display drivers to uninstall - just sound, 3D, physx, etc were in the uninstall menu.

So far I have not had the chance to plug my 1070 into another PC. I would not like to do this unless I know that PC would be safe (I don't want to mess up a friends' PC).

By the way, all my files that I'm currently working with are backed up onto a 128gb USB 3 memory stick. I am certain this is not drive failure, as both my SSD and secondary 1tb hard drive are currently working when the GPU is not plugged in.


Sorry for the long post. Please help, I'd really like to be able to use my computer properly again. Having only one monitor running off old integrated Intel graphics is highly restricting.

Any help would be much appreciated. If there's any more information I can provide please let me know.
 
I have the same issue with my 1070 as well. Something I tried, which worked is booting into safe mode, opening 'Device Manager' and uninstalling your graphics card in Display Adapters, I am not a tech guy but this seemed to have worked for me, but as soon I reinstall the 1070 graphics my monitor would turn off and windows will boot into 'Looks like windows didn't boot properly'. So I am also stuck on this part so if anyone can know the issue please help me out too.
 
You can try to preflash the vga BIOS. But before doing that, try to uninstal your driver by any of the tools out there which provide complete uninstall, then reinstall the driver (you can try with an older one) and check if it is still the same. If it is, try to preflash bios. Make sure to back it up before doing so, and to download the correct bios version for your card.
 
I found a solution but it's a pretty major one. I used the PC reset option whilst in safe mode, keeping my personal files but wiping all software and data preferences. This is the only thing that worked for me.
