Faulty GPU?

[TheLegendOfMart]

I have an ASUS RX570 Expedition GPU. When I turn the PC on I don't get a display output and the fans on the top don't spin but the white light next to the PCI-E Power connector shows white like it should indicating it has power.

The rest of my PC works:

Ryzen 3200G
ASUS B450M-K
16GB DDR4
2x SSD
1x HDD

If my PC works and GPU doesn't I can rule out the PSU being faulty?

Yes I did reset the BIOS, it was just flashed to allow Ryzen 3 support.

PSU is Corsair CX600. It's been running Intel Core i5 4440 same spec just less RAM fine.

It's not showing up in device manager, I booted into Windows using APU to see.

Is AMD different to Intel where I could leave the Intel HD graphics enabled and still output to PCI-E GPU?

It's not a new card no, it worked in my Intel system.

With the GPU in and APU enabled I don't get any output on the GPU nor does it show up in Device Manager. Yes I am using the right 8 pin PCI-E connector that goes into the PSU and not a molex adappter.

I've tried all that yes. The system boots with or without the GPU in. With the DVI connected to the APU on the board DVI I get windows output and the GPu doesn't show up in device manager.

If I plug HDMI into the 570 and use HDMI on monitor I get no signal.

I even tried enabling the 'hybrid graphics' setting in bios which would let me switch between GPUs.

Yes I switch from DVI to HDMI and get no signal. Even if I didn't switch the card would show up in device manager which it isnt...
