Build:
i7-3930k
16GB Corsair 8x2 1600MHz RAM
Intel DX79SI
Radeon 7950(previous card), trying to replace it with an RX480
Corsair TX750
180GB Intel 520 SSD
1TB Seagate Barracuda
Problem: After uninstalling 7950 drivers, taking out the card, and putting the RX480 in(And plugging in power/ensuring it was seated/screwing in the back), it displays random colors upon boot(colored square in the middle, scattered lines of colors on the outside). However, once it gets to the splash screen, the graphical errors stop and it displays the BIOS normally, after the BIOS ends, it displays the BIOS splash again, except with the previous graphical glitches, and eventually displays a black screen with the code 0_ in the bottom right corner.
This build is just under 4 years old and the only modification I've made is adding 8GB of RAM very recently, with no hiccups. Additionally, after reinserting the 7950, everything works fine, I think at this point its either a bad GPU(It displays the BIOS fine, so I doubt it), or motherboard incompatibility(It is a 4-5+ year old design).
Also, the mobo does post to 00(successful post), it just wont boot the OS
