We're trying to upgrade from the GTX 750 Ti to the GTX 1070. The video card lights up and gives video but now the computer doesn't boot. As far as we know this is the only issue.
Gives the message: "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key".
The HD we've been using is a Samsung 850 EVO.
To test it, we installed a spare HD (Samsung SSD 840) that originally booted by itself. Still no boot.
We plugged these two HD's by USB into a different PC to see if they were functional. The 850 EVO was not recognized but the SSD 840 was.
We didn't uninstall the old drivers for the 750 Ti before installing the new 1070, since most graphic card upgrades haven't had this issue.
Everything was working fine until the video card was installed. We checked all the cords to the HD and everything appears to be plugged in properly.

System specs:
Windows 10
Intel i5 3570k @ 3.4gHz
GTX 1070
EVGA 600w 80 Bronze cert 
Samsung EVO 850 500 GB
WD Blue 1 TB

huh?  the boot order got changed in the BIOS.  hit F1 or DEL or whatever to get in the BIOS.  enable "hard drive" as the first device to boot.  if that doesn't work then something happened to the HD.  also unplug the WD drive for now and see if it will boot.  some BIOS's might think it's a bootable drive.
