Graphics

So here I was buying a HIS RX480, after long thinking whether i should get a RX 480 or GTX 1060.

I thought it was a simple plug but I guess not.

Inserting the RX 480 to the pci slot causes no display to be seen (I am plugging it through HDMI to a vga adapter)

I already cleaned out all the drivers from my previous graphics card which is GTX 670. Couldn't be a pci problem because I plugged my GTX 670 back in and its running just fine, same with onboard mobo gpu. (Also no display in windows safe mode)

After reading some forums from people with the issue, i tried plugging off the rx 480 so no gpu is insterted. And making the bios boot to the integrated mobo gpu. Plug the rx 480 back in, system boots fine. From there I can see in the device manager that 2 display adapters are insterted, installed the rx 480 drivers which it successfully done so.

At this point I was hopeful I fixed it since even the computer recognizes it and the drivers are all installed. So I restarted, go to bios and set it to boot primary from the PCI. But *drum roll* NO DISPLAY.

I am stumped, I don't know what to do. This is literally my first AMD card after using nvidia since the beginning, I hope there is a fix for this.

SPECS:

WINDOWS 7 ULTIMATE

PSU: VENOM RX BOOMSLANG HEMOTOXIN EDITION 700W

16 GB DDR3 RAM

MSI Z77A-G45

i5 3570k 3.4 Ghz

Welp.

Literally after i post this I can pin point the issue it's because pci gen 3 is running. It was enabled before then i switched it to disabled now it's running. But wouldn't it effect my performance greatly?

RX 480 cards are not analogue so you can't use a DVI to VGA adaptor.  The port is DVI-D if it has one.  You would need a displayport to VGA adaptor.

Your old GTX 670 has a DVI-I port as does the motherboard.

No not particularly.

I mean i am glad it's running now, but it's becoming more of an issue of curiosity why turning on pci 3 causes it not to run

(oops i meant to say HDMI to VGA)

Well I am using a samsung syncmaster SA350 with only a dvi-d and vga port, and for some reason the dvid-d port is broken and i am forced to use vga. Even though HIS provides a dvi-d to display port adapter
