So... I bought a Sapphire R9 270x card when I was using Windows 8.1 and everything was fine. I upgraded to Windows 10 and everything was fine still for around a week, then I started getting frequent crashes. Instead of troubleshooting the problem I just decided to go back to 8.1. The downgrade went smoothly and I kept all my stuff but when the PC rebooted after the downgrade, there was no display, just "no signal" message on my screen. I restarted a couple times and nothing happened. I plugged my HDMI lead into my motherboard socket and it worked.
So now that's where I'm stuck... My onboard graphics work. My graphics card does not. It doesn't show up in device manager. I've set BIOS to use PCI-e primarily, and even turned the onboard graphics off in BIOS, I've uninstalled and reinstalled the drivers and I've even done a fresh install of Windows 8.1 and 7 (on Windows 7 currently) to try and fix it but the PC just won't detect the graphics card.
I'm going crazy. I don't know if it's windows, the BIOS, drivers or the GPU itself. Any help would be greatly appreciated!
