To explain quickly :
I was gaming with a few friends last night, when both my monitors went black, my PC then rebooted and both my monitors still were black (no HDMI signal).
When checking my peripherals, my GPU does not appear anymore, I've contatced the company where I bought it, and they asked me to do two manipulations. First one being to manually download the latest drivers (which I just can't since it always redirects me to the Radeon Software, and since my GPU isn't recognized, it fails to download the drivers).
Second one, is to test my GPU on another PC, which will be hard to do since most of my friends got those gaming laptops.
My GPU still boots on (Sapphire logo lights up) and the fans spins.
My questions now are : how/where can I find the drivers ? (without going through the Radeon Software).
Is there anything that I can try to do in order to fix it ?
Things I tried :
Uninstalling Radeon Software, installing again (fails to download drivers since no GPU is detected)
Navigating in the BIOS (nothing relevant found)
Unplugged the GPU, gave it a nice clean, and plugged back inside the case
Here are some informations about my PC specs :
CPU : Intel i5-6500 Quad Core @3.20Ghz
GPU : Sapphire Radeon RX 470 Nitro+ 4G
Motherboard : MSI B150M PRO-VDH
RAM : Crucial DIMM DDR4 8Go (2 x 4Go)
EDIT: My bad, just noticed I mistyped my GPU type, it's a 470, not 480.
Any help is welcome, thanks in advance.
