Going to boot into Windows, uninstall all Radeon stuff, restart and reinstall, but other than that I've just no idea what to do. Connected to GPU via two cables and not just one shared 6+2. PSU: Corsair something something modular 750W. RAM: 16 GB, unsure of brand and model but obviously DDR4. Help please.ĬPU: Intel 6700K I think.? Should have checked when I got into Windows I guess. I've no idea how to fix this or even what's wrong. Upgraded BIOS that way just now, nothing's changed. If I plug in HDMI (not tried DVI for this but I assume that works too) into the integrated motherboard HDMI port and unplug power to the Vega card I get signal and can boot to Windows just fine. The fans spin for a few seconds when powering on the computer, then stop. It has a small light to indicate it gets power from the two 6+2 pins required and both are on. The red LEDs on it go slowly on and off when computer is on. Only got around to plugging it in yesterday, expecting it to not be too difficult to get running.

I used to play on an RX 480 (as per title) and got a Vega 56 during Black Friday ( ).

Vega 56 fans not spinning
