GTX boots no video to monitor, so I have a black screen

[Saddler2kx]

Question, I received a brand new PNY GTX 1070 Founders edition for my AMD Ryzen pc build though I have a question. My PC was working fine with an RX 480 and a Fire Pro V7900 video card.

I've used display uninstaller to clear the amd drivers then installed my NVidia Geforce GTX 1070, while I was installing the video drivers the PC went just went black, I reset or force restart the PC and the monitor power button turns blue though still a black screen. Switched to my FirePro V7900 2GB that is working fine. What should I do, the motherboard, cpu were purchased this month, power supply is 750W by Corsair I had since last year.. Help me did I just waste 50 bucks, since I brought this sealed second hand?

sounds like the resolution could be out of range.
do you have a different monitor or tv to test.

can you boot into safe mode and change the res?

If the GPU isn't screwed in tightly to the PCI slot would that case the issue of the monitor getting a signal (power button turning from orange to blue) though screen is black not showing video on screen..
