"No signal detected" on Monitor (PC not booting when PCI-E is connected to GPU)

I've recently built my first gaming PC and wanted to see if it would work before I install my graphics card (Sapphire RX 480 8GB). Luckily, it did! But when I plugged the PCI-E cable into my RX 480 and tried to boot my computer again, the monitor said "No signal detected". I unplugged the cable from my graphics card and turned the PC on, and it worked perfectly fine. I thought this was just me, but the same thing happened to my friend (his graphics card is an Asus R9 380). I have tried doing multiple things, such as re-seating my RAM, replacing the PCI-E cable, and trying to fit it in another PCI-E slot and it still doesn't work. Could not having the current bios version and/or drivers installed yet be the issue? I was wondering if this has happened to any other person and if there was a solution to it. Thanks!

No internet yet ?, so win10 is original disc copy (not updated to latest vers ?).

Believe so. Could that be what's affecting it?

Or you haven't set the mobo bios to run off the graphics card.

How would I do that?

The Motherboard manual will have all that info on what/where to change settings.
